Meet an error when installing paddlehub

Hi developer,

When I use the latest pip to install paddlehub as follow !pip install --upgrade paddlehub

I meet the following problem,

Installing collected packages: visualdl, rarfile, easydict, paddlehub
ERROR: Exception:

Hi，I think maybe some files in wheel have chinese characters in their filenames. What if you execute 'pip install visualdl' ? If you can install this package successfully, try 'pip install --upgrade paddlehub' again.

Thanks for the response, I meet the similar error installing that package. I tried the following method searched from internet, but still not working, the same error occur.

!export PYTHONIOENCODING=utf8
!export LC_ALL=C
!pip install --upgrade setuptools

Is there any chinese character in your path ? If you can not install any package, maybe some problems happen in your environment. Check something like your username, etc.
