How to specifiy path when using pdb in emacs?

问题

I am trying to use pdb in emacs. I need to change path to PYTHONPATH=lib. But when I typed

Run pdb (like this): PYTHONPATH=lib pdb ./pychess.

Emacs gives me an error saying the file PYTHONPATH=lib isn't found. How do I specify path when running pdb in emacs? In terminal PYTHONPATH=lib pdb ./pychess runs fine, but not in emacs.

---

Oh I got it just type PYTHONPATH=lib emacs when launching emacs. Not sure about changing path after launching though...

回答1:

you can try to set the environment variable with in the emacs (say putting in .emacs or using M-:) like this

(setenv "PYTHONPATH" "lib")
