Virtualenv-Python 3-Ubuntu 14.04 64位 [英] Virtualenv - Python 3 - Ubuntu 14.04 64 bit

问题描述

我正在尝试在Ubuntu 64位14.04上为Python 3安装virtualenv.

I am trying to install virtualenv for Python 3 on Ubuntu 64bit 14.04.

我使用以下命令为Python3安装了pip:

I have installed pip for Python3 using:

pip3 install virtualenv

，一切正常.现在，尽管我尝试使用virtualenv命令来实际创建环境，并得到未安装的错误(我想是因为我尚未为Python 2安装它，而这正是它要使用的内容)

and everything works fine. Now though I am trying to use virtualenv command to actually create the environment and getting the error that it is not install (i guess because I haven't installed it for Python 2 and that is what it is trying to use)

如何为Python 3使用virtualenv?我已经搜索了文档，但是看不到它说了什么.

How do I use the virtualenv for Python 3? I have searched the documentation but can't see where it says what to do.

推荐答案

我在OS X上的开发环境中遇到了同样的问题，我可以通过简单地调用virtualenv和目标目录的路径来创建Python 3虚拟环境. .您应该能够通过以下两种方式之一创建Python 3.x虚拟环境:

I had the same issue coming from development environments on OS X where I could create Python 3 virtual environments by simply invoking virtualenv and the path to the target directory. You should be able to create a Python 3.x virtual environment in one of two ways:

1. 从PyPi($ pip3 install virtualenv)完成安装virtualenv，然后从命令行将其作为模块调用:

1. Install virtualenv from the PyPi as you've done ($ pip3 install virtualenv), then by calling it as a module from the command line:

$ python3 -m virtualenv /path/to/directory

使用 venv 模块，您可以通过apt-get. (请注意，Python 3.3是引入此模块的时间，因此此答案假定您至少正在使用该模块):

Use the venv module, which you can install through apt-get. (Note that Python 3.3 is when this module was introduced, so this answer assumes you're working with at least that):

$ sudo apt-get install python3.4-venv

然后，您可以使用以下方式设置虚拟环境

Then you can set up your virtual environment with

$ pyvenv-3.4 /path/to/directory

并使用

$ source /path/to/directory/bin/activate
