為何退出這個venv，執(zhí)行pip install MySQLdb 卻又可以了

如果你報的錯是這個

 Retrying (Retry(total=4, connect=None, read=None, redirect=None, status=None))
 after connection broken by 'ReadTimeoutError("HTTPSConnectionPool(host='pypi.or
g', port=443): Read timed out. (read timeout=15)",)': /simple/mysqldb/

你可以嘗試加大超時時間

pip --default-timeout=100 install MySQLdb

個人建議換源(清華)，速度也會加快

pip install --index https://mirrors.ustc.edu.cn/pypi/web/simple/ virtualenv

包名稱錯了。

在可以導入 MySQLdb 的環(huán)境中，通過 MySQLdb.__file__ 屬性可查出包名。

一般使用 pip install mysqlclient 安裝該模塊，而 windows 系統(tǒng)一般下載二進制安裝文件，省去編譯過程。

請參考 https://github.com/PyMySQL/my...
