配置mac环境变
# Load pyenv automatically by adding
  
       # the following to ~/.bash_profile:
  
      
   export PATH="/Users/admin/.pyenv/bin:$PATH" 
 
        eval "$(pyenv init -)
 
更新升级pyenv
 
pyenv update
 
 
 
 
pycharm指定python 版本
 
 
pyenv virtualenv 3.5.2 app
 
 
- 创建之后的目录结构为
☁  .pyenv  pwd
/Users/jerry/.pyenv
☁  .pyenv  tree -d -L 4

26 directories- 在PyCharm中为工程选择Project Interpreter
 PyCharm->Perferences->Project->Project Interperter
在弹出窗口中,点左下角的+号,add local,然后输入路径 /Users/jerry/.pyenv/versions/3.5.1/envs/new-env-3.5.1/bin/python -> 点击OK即为工程设置好相应环境的python解释器了。
