安装python模块是报错Requirement already satisfied: pymysql in c:python27libsite-packages (0.9.2) Requirement already satisfied: cryptography in c:python27libsite-packages (fr om pymysql) (2.3.1)

问题：

安装pymysql时报错

Requirement already satisfied: pymysql in c:python27libsite-packages (0.9.2)
Requirement already satisfied: cryptography in c:python27libsite-packages (fr
om pymysql) (2.3.1)

解决办法：

复制报错路径，加--target=路径  pymysql 再次安装即可

C:Userslenovo>pip.exe install --target=c:python27libsite-packages pymysql
Collecting pymysql
