If you'd prefer that conda's base environment not be activated on startup, 
   set the auto_activate_base parameter to false: 

conda config --set auto_activate_base false

Thank you for installing Miniconda3!

• 如果报错NoWritablePkgsDirError: No writeable pkgs directories configured.需要对文件夹进行权限的分配

pip install遇到"No space left on device"

• 原因：linux出现tmp空间满的情况解决

• 可用pip config set global.cache-dir ./tmpbak/ 或 pip install … --no-cache-dir
