Traceback (most recent call last):
File "test.py", line 2, in <module>
import pandas
ImportError: No module named pandas

But if I import from package path to make sure it detects Pandas library, I got this error message

解决办法：
[/code]

export LANG="it_IT.UTF-8"
export LC_COLLATE="it_IT.UTF-8"
export LC_CTYPE="it_IT.UTF-8"
export LC_MESSAGES="it_IT.UTF-8"
export LC_MONETARY="it_IT.UTF-8"
export LC_NUMERIC="it_IT.UTF-8"
export LC_TIME="it_IT.UTF-8"
export LC_ALL="it_IT.UTF-8"

I'm also enabled 

Set locale
environment variables on startup

 in the terminal preferences.
