在Ubuntu系統下安裝django時,終端下輸入:
root@ubuntu:/home/fanzhh# pip3 install django
出現如下錯誤:
pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available.

原來是下載速度太慢了,所以就切換到國內鏡像:
pip國內的一些鏡像
阿里雲 http://mirrors.aliyun.com/pypi/simple/
中國科技大學 https://pypi.mirrors.ustc.edu.cn/simple/
豆瓣(douban) http://pypi.douban.com/simple/
清華大學 https://pypi.tuna.tsinghua.edu.cn/simple/
中國科學技術大學 http://pypi.mirrors.ustc.edu.cn/simple/
修改原方法:
可以在使用pip的時候在後面加上-i參數,指定pip源
pip3 install django -i http://pypi.douban.com/simple
很快就下載成功了
如需指定需要安裝的庫requirements.txt
pip3 install -r “/home/admin/$APP_NAME/conf/requirements.txt” -i “http://mirrors.aliyun.com/pypi/simple” --trusted-host “mirrors.aliyun.com” && \ #通過阿里雲鏡像安裝三方庫
