python Could not find a version that satisfies the requirement pymysql (from versions: none) ERROR: No matching distribution found for pymysql
使用pip安装pymysql出错;Could not find a version that satisfies the requirement cryptography (from pymysql) (from versions: ) No matching distribution found for cryptography (from pymysql)
今天使用pip安装pymysql时出现如下错误:
Could not find a version that satisfies the requirement cryptography (from pymysql) (from versions: )
No matching distribution found for cryptography (from pymysql)
使用pip安装其他模块时也可能出现上述错误,主要原因是网络的问题,需要使用国内的镜像源来加速,比如豆瓣源
因此命令可以使用:
pip install pymysql -i http://pypi.douban.com/simple/ --trusted-host pypi.douban.com
或者
pip3 install pymysql -i http://pypi.douban.com/simple/ --trusted-host pypi.douban.com
即可成功安装。
