pip 修改源

python -m pip install --upgrade pip  
pip config set global.index-url https://mirrors.cernet.edu.cn/pypi/web/simple

默认配置: C:\Users\Administrator\AppData\Roaming\pip\pip.ini 

[global]  
index-url = https://mirrors.cernet.edu.cn/pypi/web/simple

pip install时 报错提示"module 'lib' has no attribute 'X509_V_FLAG_NOTIFY_POLICY'"

  File "/usr/lib/python3/dist-packages/OpenSSL/__init__.py", line 8, in <module>  
    from OpenSSL import crypto, SSL  
  File "/usr/lib/python3/dist-packages/OpenSSL/crypto.py", line 1553, in <module>  
    class X509StoreFlags(object):  
  File "/usr/lib/python3/dist-packages/OpenSSL/crypto.py", line 1571, in X509StoreFlags  
    NOTIFY_POLICY = _lib.X509_V_FLAG_NOTIFY_POLICY  
AttributeError: module 'lib' has no attribute 'X509_V_FLAG_NOTIFY_POLICY'

临时解决: 重命名crypto.py可临时解决

mv "/usr/lib/python3/dist-packages/OpenSSL/crypto.py" "/usr/lib/python3/dist-packages/OpenSSL/crypto.py.bak"
