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
- 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
- 让配置生效:
source ~/.bash_profile
- 再试一下,大功搞成!!!
