virtualenv -p python3.5 namevenv

The answer is in English. https://stackoverflow.com/questions/34271982/install-python3-venv-module-on-linux-mint When python-venv is installed, the Ubuntu index should be introduced Python♪ In this case, it's python3. 4.Codesudo apt-get install python3.4-venvThereafter, there are no described errors.

There was a mistake in the team.virtualenv oscar There was a oscar folder in this folder, deleted it.

It turned out to be too easy. The Russian name of the Docupier's folder has been obsessed.

First, venv is often used in sales, including even in low-cost hostings, and it will be used by no one on the designated server.And how to turn the apps is a big subject. Someone's using docker-containers or something. In the simplest case, there's a package of plus requirements.txt, because there's a way to point out the library versions you need. venv is good for making an environment for each project. Otherwise, switching from the project to the project would require a reset of the library versions.

You can just build a nginx (apache or other web server) to make this file a static one.

Every virtual environment has a small violin to activate, Anaconda probably wrote its own in PATH, so the team activate in the terminal just activates the environment. Anaconda3♪ To circumvent the activation crypt, which specifically relates to the desired environment by recruiting:D:\CODE\Python\Django\myCMS\Scripts\activate

The error arises because no head file has been found (Modules/LDAPObject.c:18: fatal error: sasl.h: No such file or directory) necessary for the compilation of python-apld( https://pypi.python.org/pypi/python-ldap ) Some python packages contain parts of the packages implemented on C and therefore need to be compiled. However, because of possible incompatibility, pypi does not have pre-compiled linux packages and the compilation should be carried out in the car.Installation of appropriate headlines can be usedsudo apt-get install libsasl2-devIt might also be necessary to establish a python-dev and libldap2-dev.sudo apt-get install python-dev libldap2-devAbout requirements.txt, this file just keeps a list of addictions. It may become a problem if it contains an incorrect name/version of the package or if the package(s) is missing from the pypi.

Don't use it. sudo pip To put Pitton in the system files. Ubuntu system packages should be managed by an appropriate package manager, for example through apt-get client of the line team. Important systems utilises can depend on the system python, so they can stop working if you break your Piton installation.For your user, you can use --user Opium:$ python3.4 -m pip install --user virtualenv -U Make sure ~/.local/bin folder on the way$PATHis.We could use the rig without the installation. http://virtualenv.readthedocs.org/en/latest/installation.html ♪

Ubuntu 14.04 No official python3-pygame Package, so the next step is to use PPA, for example https://launchpad.net/~thopiekar/+archive/ubuntu/pygame recommended for https://askubuntu.com/a/97721/3712 $ sudo apt-get install -y software-properties-common && # для add-apt-repository sudo add-apt-repository -y ppa:thopiekar/pygame && # где взять python3-pygame sudo apt-get update -y && # обновляем список пакетов sudo apt-get install -y python3-pygame # ставим After that. python3 -c 'import pygame' The team has to work.Attention: PPA may contain whatever their authors want -- put your fear and risk on. Unless the virtual environment works and the environment does not work, either the environment is created for another Piton version or the virtualenv does not include system packages (--system-site-packages (option) -- re-establish the environment.

Try this:# -*- coding: utf-8 -*- import os, sys, site site.addsitedir('/var/www/myproject/env/lib/python3.4/sitepackages') sys.path.append('/var/www/myproject/env/bin') sys.path.append('/var/www/myproject/src/myproject') os.environ['DJANGO_SETTINGS_MODULE'] = 'myproject.settings' virtualenv = os.path.join('/var/www/myproject/env/', 'bin', 'activate') try: exec(compile(open(virtualenv).read(), virtualenv, 'exec'), dict(file=virtualenv)) except: pass from django.core.wsgi import get_wsgi_application application = get_wsgi_application()

It is not the worst practice to googling the entire text of the error. In this case,error: command 'gcc' failed with exit status 1 A lot of stackoverflow discussions will help to understand what's going on, and councils likesudo apt-get install python-dev sudo apt-get install libevent-dev It's probably gonna solve all the problems.

tk - standard lib, so it doesn't need to be set up in a virtual environment. ♪ tk Work, the python has to be assembled with certain constructions.In ubonte, a package can be installed instead of a bulkhead. python-tk/python3-tk

If you're not familiar with the intruding, I strongly recommend that you study it. I'll compare this tool to the end of the answer.It works as a group of files to the directory (e.g.: env/and then modified the variable environment PATH Adding a prefix to the user directory bin (e.g.: env/bin/) An exact copy of the binary python or python3 It's scattered in this directory and Python programmed to search for a library on this route first, in the director of the environment. This instrument is not part of the standard library Python, but is officially blessed. https://www.pypa.io/en/latest/ ♪ Units activated, you can put boxes into virtual space using pip♪ https://github.com/yyuu/pyenv used to insulate python versions. For example, you'd like to test your code for Python 2.7, 3.6, 3.7 and 3.8, then you'd need a decision to switch between them. After activation, to a variable environment PATH Added ~/.pyenv/shimswhere Python team matching files are locatedpython♪ pip) It's not a copy of Python's crew, but special violets who decide for the summer what Python's version to launch, based on the basis of PYENV_VERSION- removable environment or .python-version-File or ~/.pyenv/version file. pyenv also facilitates downloading and installation of several Python versions using the team pyenv install♪ https://github.com/yyuu/pyenv-virtualenv is a flame pyenvfrom the same author pyenv and makes it easy to use pyenv and virtualenv at the same time. However, if you use Python 3.3 or above, pyenv-virtualenv I'll try to start. python -m venvif available, otherwise virtualenv♪ You can use it. virtualenv and pyenv together, without pyenv-virtualenvif you don't need a convenient function. https://pypi.python.org/pypi/virtualenvwrapper - it's a set of extensions to virtualenv (See. http://virtualenvwrapper.readthedocs.io/en/latest/ ) You have teams like this. mkvirtualenv♪ lssitepackages and in particular workon different catalogues virtualenv♪ This tool is particularly useful if you need a few catalogues. virtualenv♪ https://github.com/yyuu/pyenv-virtualenvwrapper - it's a flame. pyenv the same author, for easy integration virtualenvwrapper Total pyenv♪ https://pypi.python.org/pypi/pipenv - to eat.

It distinguishes this instrument from virtualenvwhere the directory is usually located in the project file. pipenv for use in the development of Python applications (as opposed to libraries). Alternatives pipenvlike https://pypi.org/project/poetry/ which I will not list here, as this issue concerns only packages with similar names.Standard librariespyvenv (not confused with https://github.com/yyuu/pyenv From the previous part, it's a crypt from Python 3, but https://docs.python.org/dev/whatsnew/3.6.html#id8 because there were problems (not to mention a confused name). Python 3.6+, exact equivalent - python3 -m venv♪ https://docs.python.org/3/library/venv.html - it's a Python 3 package you can start with help. python3 -m venv (although for some reasons some distribu distributives are a separate package, such as python3-venv Ubuntu/Debian). He serves the same purpose as that. virtualenvbut only has multiple functions ( https://virtualenv.pypa.io/en/latest/ ) virtualenv still more popular than venvespecially since the first one supports both Python 2 and 3.

I didn't answer the comment. Let's go.The problem could have arisen from the installation of several packages, for example:pip install -r requirements.txt and one of them made a mistake. It happens often at the wrong place. or lazy developers, when the environment is moved from windows to linux. And the vinda packages are on the list of addictions.It was that the packages were wrapped up, but not installed and through. pip freeze Don't see them.What can be done:Take a look pip'apython -m pip cache list If my guess is correct, the sheet will contain all your bags. They can be removed from the cash or separately.python -m pip cache remove And repeat the installation of the packages separately or already, which does not want to be installed https://pip.pypa.io/en/stable/cli/pip_cache/ I don't know what I'm saying.And an additional option. From the requirements.txt remove the conflicting package, repeat the installation without it. And then he's the only one who's ever been screaming.Naturally, all manipulations with an active virtual environment

No, a virtual environment will not be created by itself.Repository cloning is no more than a file operation, oa is not dependent on either the operating system or the verbal sophth.The creation of a virtual environment is closely linked to the installed python and affects the configuration of the comp - in blatant words, when VENV is established, certain libraries are placed in certain folders.In fact, cloning and everything that comes to the compilation - interpretation - assembly is different processes.I'd do that: I'm inclined, and manually created a viral environment.

He doesn't have to download anything after he activated it.conda activate ./myenv Piton's on herll.python app.py python.exe finds itself in myenv. It's only necessary from inside. virtualenv shell I' binarys. numpy I can only launch anacon of console. Check the Piton version:python --version Where the improvised libs are:import sys print(sys.path) Although if it's not anaconda, try to redesign the path like this, Set ./.vscode/settings.json so:{ "python.pythonPath": "myenv\\python.exe" "terminal.integrated.shell.windows" : "C:\\Windows\\system32\\cmd.exe", "terminal.integrated.shellArgs.windows": [ "/K","activate.bat" ] } Then the right button of mouse on the launch squeak and Run Python File in Terminal. So I started anaconda (venv) projects until the numpy pyd stopped loading, now everything through shell. It's possible to automate after shell activated (or through cmd or through settings.json)- Circumstances by the right button of mouse on the launch violin and Run Python File in Terminal. Everything works. PS. It happens that even after that, I didn't see that the virtual environment was in another folder, rebooting, asking for the same interpreter (as in settings.jsonson) and putting the same into works, I guess.

I see a problem with my modest experience in the event that a number of projects are being developed/implemented in this car. Each project is linked to its versions of piton and libraries. They're not always compatible with bagos. As a result, every renovation and installation of the new library will touch all the projects in the car, not just one for which you're updating something. Because of the buck, or that some function has changed or redesigned, you may suddenly stop running any of the projects that use the library.

I feel like the interpreter doesn't find a python3 in this environment and takes it out of here (maybe you have some piton versions). Try it.py test_function.py orpython test_function.py I'd write in the commentary, but the carmas are still missing.

Python 3 is a very good vein, so you can just.../home/t/wf/env/bin/python -m idlelib Not only if she's not even there. But when the console works, it should work.The environment can also be challenged by PYTHON_PATH.
