# -*- coding: utf-8 -*- error

scloudyy commented 8 years ago

When type # -- coding: utf-8 -- on the top of buffer in each file error will occur, and cursor can hardly move. When type #!/usr/bin/env python3 will also make this error.

Do you use rope_py3k?

jorgenschaefer commented 8 years ago

Hello, and thanks for the report! This is a bug in Rope when using Python 3. You will have to use the rope_py3k package instead of the rope package if you use Rope with Python 3. Does this help?

scloudyy commented 8 years ago

Thanks for your quick reply . So how can I change rope to rope_py3k? just

pip uninstall rope
pip install rope_py3k

?

jorgenschaefer commented 8 years ago

That should work, yes. Also restart Elpy (M-x elpy-rpc-restart)

Lacking further updates, I assume this problem is solved. Please do not hesitate to open a new issue if you have any further problems.
