[英]Error message for virtualenvwrapper installed with homebrew on Mac Sierra
I installed virtualenv and virtualenvwrapper using homebrew, but am getting the following error when I try source virtualenvwrapper.sh
我使用自制软件安装了virtualenv和virtualenvwrapper,但是尝试source virtualenvwrapper.sh
时出现以下错误

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.
My .bash_profile looks like this: 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
I have a mac running Sierra (10.12.4). 我有一台运行Sierra(10.12.4)的Mac。
Any help appreciated! 任何帮助表示赞赏!
I've got macOS 10.12.6
and python 2 installed via homebrew. 我已经通过自制软件安装了macOS 10.12.6
和python 2。
What worked for me was to make sure that homebrew python is in front of the system python in $PATH
env variable by adding export PATH="/usr/local/opt/python/libexec/bin:$PATH"
. 对我有用的是,通过添加export PATH="/usr/local/opt/python/libexec/bin:$PATH"
确保自制python在$PATH
env变量中位于系统python的前面。
The relevant part of my .zshrc
looks like this: 我的.zshrc
的相关部分如下所示:
## 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
I've got this idea from the formula documentation: 我从公式文档中得到了这个主意:
» brew info python
python: stable 2.7.13 (bottled), HEAD
# (...)
==> Caveats
This formula installs a python2 executable to /usr/local/bin.
If you wish to have this formula's python executable in your PATH then add
the following to ~/.zshrc:
export PATH="/usr/local/opt/python/libexec/bin:$PATH"
# (...)
I suspect for bash it is the same. 我怀疑bash是一样的。
