問題描述
執行pip install 發現以下報錯：
Could not fetch URL https://pypi.org/simple/requests/: There was a problem confirming the ssl certificate: HTTPSConnectionPool(host='pypi.org', port=443): Max retries exceeded with url: /simple/requests/ (Caused by SSLError(SSLEOFError(8, 'EOF occurred in violation of protocol (_ssl.c:1123)'))) - skipping
看報錯描述，猜測是https證書校驗問題，最簡單的解決方案是使用http鏡像地址，步驟如下：
1、創建pip組態檔
查看組態檔路徑：
C:\Users\Loren\PycharmProjects\pythonProject\venv\Scripts>./pip.exe -v config list
For variant 'global', will try loading 'C:\ProgramData\pip\pip.ini'
For variant 'user', will try loading 'C:\Users\EchatDev\pip\pip.ini'
For variant 'user', will try loading 'C:\Users\EchatDev\AppData\Roaming\pip\pip.ini'
For variant 'site', will try loading 'c:\users\echatdev\pycharmprojects\pythonproject\venv\pip.ini'命令會輸出各個級別的pip組態檔路徑，這里選擇全域配置'global'，找到C:\ProgramData\pip\pip.ini檔案，如果沒有則創建，
2、配置鏡像地址
打開pip.ini，添加鏡像配置：
[global]
index-url=http://mirrors.aliyun.com/pypi/simple/
[install]
trusted-host=mirrors.aliyun.com這里使用的阿里云的鏡像地址，相對速度比較快，需要添加trusted-host，
配置完成之后，重新執行pip install即可成功，
