python35&&python27在windows启动时报错解决方案

Posted 2020-06-23

cmd>python3

 Fatal Python error: Py_Initialize: unable to load the file system codec
ImportError: No module named ‘encodings‘

Current thread 0x00001f28 (most recent call first): 

 

cmd>python2

No modules named XX

 

 

原因：环境变量更改后造成的问题。需要修改环境变量增加一些路径：

 

%python35%

D:\Program Files\Python35\Scripts\;D:\Program Files\Python35\;D:\Program Files\Python35\Lib;D:\Program Files\Python35\Lib\site-packages;D:\Program Files\Python35\DLLs

 

%python27%

D:\Program Files\Python27\;D:\Program Files\Python27\Scripts;D:\Program Files\Python27\Lib;D:\Program Files\Python27\Lib\site-packages;D:\Program Files\Python27\DLLs

 

在环境变量中增加之后完美生效
