How to Fix Python Fatal error: Py_Initialize: Unable to get the locale encoding [Solved]

Updated on September 1, 2017

I had successfully compiled Python3.5 from source. But when I execute ‘python3.5‘ command, I get an error message as “Fatal Python error: Py_Initialize: Unable to get the locale encoding. ImportError: No module named encodings“.

Here’s the complete error message:

# python3.5
 Fatal Python error: Py_Initialize: Unable to get the locale encoding
 ImportError: No module named 'encodings'
 Current thread 0x00007ff41bf46700 (most recent call first):
 Aborted (core dumped)

What could be the problem?

python module error


The problem might be due to multiple Python installations on your machine and the command ‘python3.5‘ might be referring to libraries that belong to a different version of Python. Well, there could be another reason – the command ‘python3.5‘ is not able to find PYTHON installation path. The below lines will be a good try for this error:

# export PYTHONHOME=/usr/local/lib/python3.5/
# export PYTHONPATH=/usr/local/lib/python3.5/

Note: Make sure to set the correct installation path of Python3.5.

Now, try invoking python3.5 and it should work.

# python3.5
Python 3.5.0 (default, Nov 6 2015, 16:57:04)
[GCC 4.4.7 20120313 (Red Hat 4.4.7-11)] on linux
Type "help", "copyright", "credits" or "license" for more information.

  1. Didn’t work for me, (linux). Can you remove that [Solved] from the header – it is misleading.
