Python 2.7 : LookupError: unknown encoding: cp65001
Question:
I have installed python 2(64 bit), on windows 8.1 (64 bit) and wanted to know pip version and for that I fired pip --version
but it is giving error.
C:UsersADMIN>pip --version

six.text_type().join(characters).encode(encoding)
LookupError: unknown encoding: cp65001
Note : The same command works fine for python 3. I have uninstalled both and installed again but still no success.
Answers:
First of all you need to upgrade your pip.
You can do this in Windows by:
python -m pip install -U pip
Then go manually to your script folder, enter command line from that folder (you can do this by clicking shift + right mouse button -> Open console window), and then you should use one of this commands.
pip -V
pip --version
This will result in
pip 7.1.2 from c:python27libsite-packages (python 2.7)
If you still have trouble, you can try to remove your current Python PATH, and add a new one to Python 2.7.
The error means that Unicode characters that your script are trying to print can’t be represented using the current console character encoding.
Also try to run set PYTHONIOENCODING=UTF-8
after execute pip –version without reloading terminal if everything going well add PYTHONIOENCODING
as env variable with value UTF-8
. See How to set the path and environment variables in Windows article to get info how to add Windows variable.
NOTE: For PowerShell use $env:PYTHONIOENCODING = "UTF-8"
Also you can try to install win-unicode-console with pip:
pip install win-unicode-console
Then reload your terminal and try to execute pip --version
However you can follow suggestions from Windows cmd encoding change causes Python crash answer because you have same problem.
