pip:找不到激活的virtualenv(必填) [英] pip: Could not find an activated virtualenv (required)

问题描述

我正在尝试在mac osx 10.8.3上安装virtualenv和/或virtualenvwrapper

I am trying to instal virtualenv and/or virtualenvwrapper on a mac osx 10.8.3

最近两天我一直在和python战斗.最终，我能够使用brew安装python 2.7.4.在我使用easy_install安装virtualenv之前.然后，我尝试将其卸载，以使我的计算机处于与我的一位同事相同的状态.也许我成功卸载了它，也许没有成功.我不知道如何测试.现在我应该使用-

I have been fighting with python for the last two days. Finally I was able to install python 2.7.4 using brew. Before I had virtualenv installed using easy_install. Then I tried to uninstall it, trying to get my computer in the same situation as the one of my colleagues. Maybe I uninstalled it with success, maybe not. I don't know how to test it. Now I am supposed to install virtualenv using -

pip install virtualenv

但这给了我-

Could not find an activated virtualenv (required).

pip install virtualenvwrapper给出完全相同的输出.

pip install virtualenvwrapper gives exactly the same output.

另外变量:PIP_RESPECT_VIRTUALENV为空:

echo $PIP_RESPECT_VIRTUALENV

我该如何解决这个问题?

How can I solve this issue?

谢谢

推荐答案

打开您的~/.bashrc文件，查看是否存在该行-

Open your ~/.bashrc file and see if this line is there -

export PIP_REQUIRE_VIRTUALENV=true

这可能是造成麻烦的原因.如果存在，将其更改为false并运行-

It might be causing the trouble. If it's there, change it to false and run -

source ~/.bashrc

如果没有，请从终端运行export PIP_REQUIRE_VIRTUALENV=false.

If not, run export PIP_REQUIRE_VIRTUALENV=false from terminal.

注意:如果当前用户的根目录中使用的是.bash_profile而不是.bashrc，则所有操作均相同.

Note: everything works the same if you have .bash_profile instead of .bashrc in your current user's root directory.
