如何将 virtualenv 添加到路径 [英] How to add virtualenv to path

问题描述

我试图找出为什么我的 virtualenv 和/或 virtualenv 包装器 - 使用 pip 安装，使用 homebrew - 找不到.我认为这是因为它没有添加到我的 PATH 中:

I am trying to find out why my virtualenv and/or virtualenv wrapper - installed using pip using homebrew - cannot be found. I think it's because it's not added to my PATH:

$ which virtualenv
$ 

和:

$ virtualenv someDir
$ -bash: virtualenv: command not found

我使用 homebrew 安装了 pip，使用 pip 安装了 virtualenv，没有问题.我尝试重新安装 virtualenv，但这也不起作用.我如何知道要添加到 PATH 的路径?只是 virtualenv.py 似乎安装到的路径?好像是:

I installed pip using homebrew, and virtualenv using pip, without problems. I tried reinstalling virtualenv, but that did not work either. How do I know what path to add to PATH? Just the path that virtualenv.py seems to be installed into? That seems to be:

/usr/local/lib/python2.7/site-packages/virtualenv.py

我还找到了本指南，其中暗示了这一点:

I also found this guide, which suggests this:

$ ln -s ../Cellar/python/2.7/Frameworks/Python.framework/Versions/2.7/bin/virtualenv virtualenv

然而，它并不能帮助我运行 virtualenv.我使用的是 Mac OSX 10.7.5 (Lion).

However, it does not help me run virtualenv. I am on Mac OSX 10.7.5 (Lion).

推荐答案

对于几乎所有简单"安装过程，我自己似乎是规则的例外.出于某种原因，这是一个与路径相关的问题:

It seems that I myself am the exception to the rule for almost all 'simple' installation procedures. For some reason, it WAS a path related issue:

我跑了brew info python，输出了很多信息.在底部我发现了这个:

I ran brew info python, which outputted a lot of information. At the bottom I found this:

Executable python scripts will be put in:
/usr/local/share/python
so you may want to put "/usr/local/share/python" in your PATH, too.

我将它添加到 /etc/launchd.conf 和 ~/.bashrc 中的 PATH 中，瞧:

I added that to my PATH in /etc/launchd.conf and ~/.bashrc and lo and behold:

$ which virtualenv 

告诉我:

"/usr/local/share/python/virtualenv"

我仍然不知道为什么我无法在网上、任何地方找到任何指向正确方向的指示?pip install virtualenv 是否应该添加到 PATH 本身?如果是这样，为什么不在我的系统上?为什么@bibhas 明确告诉我这不是路径问题?

I still don't know why I couldn't find any pointers in the right direction, online, anywhere? Is pip install virtualenv supposed to add to the PATH itself? If so, why not on my system? Why did @bibhas tell me explicitly it was not a path issue?
