Spyder Launch Error

When I run spyder on command line, I got error message like below.

I have tried

1. Reinstall using "pip install spyder"
2. Reinstall using "conda install spyder"
3. On the command line "spyder --reset"

Version Information(

• Spyder Version: 3.0
• Python Version: 2.7.12
• Operating system: Ubuntu 14.04
• Anaconda Version : 4.2.0

How do I fix it. If you give me some ideas, I can really appreciate for this.

Thanks.

@eunsoo, as was asked on #3127, could you please include the output of running

printenv

in a terminal (i.e. in bash or zsh :-) For some reason, a non-ascii character (perhaps Hangul) has crept in.

If you can switch to Python 3, that might turn out to help, as Python 3 is generally better with non-ascii characters.

@mariacamilaremolinagutierrez, please work on this one. To reproduce it, please create a conda environment with all Spyder dependencies in a directory with non-ascii chars (e.g. /tmp/añño), and run Spyder from it.

I think that would reproduce this problem, but if not, please let me know about it :-)

@ccordoba12 I was not able to reproduce the error, I was trying several configurations. But only until now I realized all this time I was using python 3.5, so I am going to install it again with python 2.7

[ccordoba12]

Ok, thanks :-)

[mariacamilarg]

I was able to reproduce it by naming the conda environment with a non-ascii character:

I will find out later today how to fix that

[ccordoba12]

This means that Python itself doesn't even work when installed in a non-ascii dir on Unix systems, but that's not directly related to the original problem :-/

We'll discuss about this in our meeting, please work on your other issue instead :-)
