python -ImportError: No module n

确保正确设置了PYTHONHOME环境变量。

如果PYTHONHOME指向无效的位置或您要运行的其他Python安装，您将收到此错误。

试试这个：

C:\>set PYTHONHOME=C:\Python27C:\>python

用

setx PYTHONHOME C:\Python27

将其永久设置为后续命令提示符

快速解决方案：设置PYTHONHOME和PYTHONPATH并在PATH上包含PYTHONHOME

例如，如果您安装到c：\ Python27

set PYTHONHOME=c:\Python27

set PYTHONPATH=c:\Python27\Lib

set PATH=%PYTHONHOME%;%PATH%

Windows:

setPATH="path\to\Clarisse";%PATH%

setPYTHONPATH="path\to\Clarisse\python";%PYTHONPATH%

Linux:

export PATH="path/to/Clarisse/":$PATH

export PYTHONPATH="path/to/Clarisse/python":$PYTHONPATH

export LD_LIBRARY_PATH="path/to/Clarisse":"path/to/Clarisse/python":$LD_LIBRARY_PATH

macOS:

export PATH="path/to/Clarisse/":$PATH

export PYTHONPATH="path/to/Clarisse/python":$PYTHONPATH

export DYLD_LIBRARY_PATH="path/to/Clarisse":"path/to/Clarisse/python":$DYLD_LIBRARY_PATH
