找不到windows 10 python串行模块，但pip安装pyserial已通过

Question

C:\Users\antvai01\Linux\host\tests>python -m pip install pyserial
Defaulting to user installation because normal site-packages is not writeable
Requirement already satisfied: pyserial in c:\users\antvai01\appdata\roaming\python\python37\site-packages (3.5)

我甚至从源码上手动安装了pyserial，仍然存在同样的问题。有什么想法吗？

Answer 1

它正在安装到非默认位置：

Defaulting to user installation because normal site-packages is not writeable
Requirement already satisfied: pyserial in c:\users\antvai01\appdata\roaming\python\python37\site-packages (3.5)

此位置可能不在您的PYTHONPATH中。

我想看看为什么你的正常站点包文件夹是不可写的
