Cannot uninstall 'certifi'. It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall.

你期待的结果是什么？实际看到的错误信息又是什么？

然后在使用pip list 查看安装的环境是时发现一个也没有安装成功

(active_env) [root@localhost Crm_Project]# pip list

找到原因了，发现跟命令和环境没有关系

补充日志：

THESE PACKAGES DO NOT MATCH THE HASHES FROM THE REQUIREMENTS FILE. If you have updated the package versions, please update the hashes. Otherwise, examine the package contents carefully; someone may have tampered with them.
    certifi==2016.2.28 from https://pypi.doubanio.com/packages/db/60/1ed0106bde7b14b363b15b17cc308aad93ba57d3582570f3ad7180ae0fae/certifi-2016.2.28-py2.py3-none-any.whl#md5=409448ee124f3159d912e4e155b034b0 (from -r requirements.txt (line 3)):
        Expected md5 409448ee124f3159d912e4e155b034b0
             Got        cf44bfe940b61be89ea6c82dc04f44e6

是更新时，校验值不一样导致的

解决方法：

在requirements.txt文件中删除certifi==2016.2.28就可以了
