问题
I am trying to setup python 2.7.6 on my windows 7 machine (python 3.3.3 was installed first). When selecting the project interpreter after adding it in settings-project interpreter, I get this error
File "C:\Python33\Lib\site.py", line 173 file=sys.stderr) ^ SyntaxError: invalid syntax
When initially adding the python 2.7 interpreter in the settings page (as compared to adding the virtual environment above), it gives this error message
Cannot setup python SDK at C: .... . The SDK seems invalid.
I also get a similar error when adding any virtual env based on that interpreter.
I've added the python27 paths in the Paths box as in the picture, but it seems to be looking at the path set in windows. If I have to change that, doesnt that defeat the point of being able to select multiple interpreters?
Any help would be greatly appreciated.
回答1:
I made a really silly mistake: I was messing with PYTHONPATH instead of PATH. I added both PYTHON33 and PYTHON27 to my PATH and it worked.

Try adding these commands before you run your UI
set PYTHONHOME=C:\Python33
set PYTHONPATH=C:\Python33\lib
