Pip使用virtualenv将软件包安装在错误的目录中 [英] Pip installs packages in the wrong directory with virtualenv

问题描述

在OS X上使用Python 3.7 然后我设置了一个虚拟环境

With Python 3.7 on OS X I set up a virtual environment then

    $ source venv/bin/activate
    $ pip install numpy
    $ which pip 
pip is /Users/me/PycharmProjects/Test1/venv/bin/pip
(venv) 

但不是将其安装在虚拟环境中，而是将numpy安装在

But rather than installing in the virtual environment numpy is installed in

/usr/local/lib/python2.7

和numpy没有出现在pip list

通过Python下载或brew安装的Python均会出现问题.

The issue occurs with both Python installed via the Python download or via brew.

可能的设置可能导致该软件包安装在错误的位置.

What possible settings could be causing the package to be installed in the wrong location.

推荐答案

回答我自己的问题.

有一个看不见的

~/.config/pip/pip.conf 

文件.包含以下几行:

[global]
target = /usr/local/lib/python2.7/site-packages

该文件已有几年历史，所以我不确定它是如何到达的，但是删除它可以解决问题.

This file was a few years old, so I'm unsure how it got there but removing it resolved the issue.
