1. 前言

2. 问题说明

Mac默认系统的python2,而我自己用的是brew安装的python3

下面是我安装过程中出现的问题

  1. 安装virtualwrapper,打开终端,输入如下的命令
pip3 install virtualenv
pip3 install virtualenvwrapper
  1. 在配置文件~/.bash_profile中添加代码
# Settings for virtualenvwrapper
export WORKON_HOME=$HOME/.virtualenvs
source /usr/local/bin/virtualenvwrapper.sh
  1. 让配置生效
source ~/.bash_profile

这时,出现了如下问题:

/usr/bin/python: No module named virtualenvwrapper
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/bin/python and that PATH is
set properly.

3. 原因分析

从报错信息VIRTUALENVWRAPPER_PYTHON=/usr/bin/python and that PATH is set properly.这一句话来看,是环境指向python2的路径,所以我们只需要将这个环境变量修改为python3的路径即可。

4. 解决办法

  1. 打开配置文件
vim ~/.bash_profile
  1. 在配置文件中添加一行代码
export VIRTUALENVWRAPPER_PYTHON=/usr/local/bin/python3
  1. 让配置生效, 大功告成
source ~/.bash_profile
