Ubuntn下Django开发问题总汇(不定期更新)

１、使用：sudo apt-get update　，错误描述：E: Repository 'http://dl.google.com/linux/chrome/deb stable Release' changed its 'Origin' value from 'Google, Inc.' to 'Google LLC'
N: This must be accepted explicitly before updates for this repository can be applied. See apt-secure(8) manpage for details.

解决：改用　sudo apt update

２、pip ，错误描述：Traceback (most recent call last): File "/usr/local/bin/pip", line 7, in <module> from pip._internal import main ModuleNotFoundError: No module named 'pip._internal'

  解决：$:   wget https://bootstrap.pypa.io/get-pip.py --no-check-certificate　或者　curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py

　　　$: 接着运行命令，给python2安装pip，命令：python get-pip.py；　给python3　安装 pip3 ，命令：python３ get-pip.py
