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

2. 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

3. 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.

原因分析

从报错信息中 VIRTUALENVWRAPPER_PYTHON=/usr/bin/python and that PATH is set properly. 这一句话来看,是环境指向了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。

解决办法

  1. 打开配置文件 vim ~/.bash_profile 在配置文件中添加一行代码:export VIRTUALENVWRAPPER_PYTHON=/usr/local/bin/python3
  2. 让配置生效:source ~/.bash_profile
  3. 再试一下,大功搞成!!!
