Question

我使用自制软件安装了virtualenv和virtualenvwrapper，但是当我尝试source virtualenvwrapper.sh时出现以下错误

Traceback (most recent call last):
  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/runpy.py", line 162, in _run_module_as_main

virtualenvwrapper.sh: There was a problem running the initialization hooks. 

If Python could not import the module virtualenvwrapper.hook_loader,
check that virtualenvwrapper has been installed for
VIRTUALENVWRAPPER_PYTHON=/usr/local/bin/python and that PATH is
set properly.

我的.bash_profile看起来像这样：

export PATH=/usr/local/bin:$PATH
# virtualenvwrapper
export WORKON_HOME=$HOME/.virtualenvs
export VIRTUALENVWRAPPER_PYTHON=/usr/local/bin/python
export VIRTUALENVWRAPPER_VIRTUALENV=/usr/local/bin/virtualenv
source /usr/local/bin/virtualenvwrapper.sh

我有一台运行Sierra的Mac（10.12.4）。

任何帮助表示赞赏！

Answer 1

如果将来有人发现这有用，那么对我有用的是安装conda而不是virtualenv。

无论出于何种原因安装conda后，virtualenv也开始工作了。

Answer 2

我通过自制软件安装了\ir和python 2.

对我来说有用的是通过添加macOS 10.12.6来确保自制的python位于$PATH env变量的系统python前面。

export PATH="/usr/local/opt/python/libexec/bin:$PATH"的相关部分如下所示：

.zshrc

我从公式文档中得到了这个想法：

## Python
export PATH="/usr/local/opt/python/libexec/bin:$PATH"  # homebrew python 2 in front of the system one
export WORKON_HOME="$HOME/Virtualenvs"
source /usr/local/bin/virtualenvwrapper.sh

我怀疑bash是一样的。
