Python:pip 尝试安装到/bin 目录

Question

我用brew install python安装了python

which pip
/usr/local/bin/pip

我的 PYTHONPATH 显示 /usr/local/lib/python2.7/site-packages/

但是，当我尝试使用 pip 安装某些东西时，它会进入 /bin/ 目录，如下所示。我想把东西安装到 /usr/local/lib/python2.7/site-packages/。我该如何解决？

pip install virtualenv

$ pip list
pip (1.5.6)
setuptools (5.4.2)

$pip show setuptools

因此 pip 已经将基本包安装到 site-packages 中。但是，运行完全相同的 pip 来安装 virtualenv 会尝试安装到/bin/。

我在尝试安装 virtualenv 和 flask 时遇到了同样的问题。结果我的主目录中有一个 .pydistutils.cfg 文件。我记得不久前把它放在那里作为安装其他东西的解决方法。删除此文件后，运行 pip install 继续按预期工作。
