This problems has been solved since v1.14

The site module provides site.PREFIXES that is the key information I need to fix this problem. See __init_.py.

The workaround

After pip3 install peforth if peforth makes "file not found" error on your Ubuntu, the solution is: manually copy all files in ~/.local/lib/site-packages/peforth to ~/.local/lib/python3.5/site-packages/peforth then it will work. Do this again for an upgrade.

Description

On Windows 10 after pip install peforth the package of 7 files (so far) are all in one folder :

Volume in drive C is Windows
 Volume Serial Number is ACE4-3690

 Directory of c:\Users\hcche\AppData\Local\Programs\Python\Python36\Lib\site-packages\peforth

2017-10-11  08:32            63,728 peforth.f
2017-10-09  09:49            20,715 peforth.selftest
2017-09-25  09:38            20,392 projectk.py
2017-10-11  10:08             6,202 quit.f
2017-10-11  11:24                20 version.txt
2017-10-11  12:14             4,443 __init__.py
2017-10-09  09:49               233 __main__.py

On Ubuntu Linux, they appear in different folders:

.py files are in ~/.local/lib/python3.5/site-packages/peforth
    __init__.py  __main__.py  projectk.py

other files are in ~/.local/lib/site-packages/peforth
    peforth.f  peforth.selftest  quit.f  version.txt

that makes a file not found problem because __init__.py expects data files at the same folder where it is. I didn't find an acceptable solution but a workaround which is simply to manually copy all files in ~/.local/lib/site-packages/peforth to ~/.local/lib/python3.5/site-packages/peforth then peforth will work fine.

Records of my studies

None of the below findings work, either don't they meet the needs of peforth or that I can't handle the correct path things of Linux. Anyone know of the correct method to get the two paths please let me know or modify the init.py directly for Ubuntu or other Linux.

OK py:~ import distutils.sysconfig as config; push(config)
OK constant config
OK config dir . cr
['BASE_EXEC_PREFIX', 'BASE_PREFIX', 'DistutilsPlatformError', 'EXEC_PREFIX', 'PREFIX', '__builtins__', '__cached__', '__doc__', '__file__', '__loader__', '__name__', '__package__', '__spec__', '_config_vars', '_findvar1_rx', '_findvar2_rx', '_imp', '_init_nt', '_init_posix', '_is_python_source_dir', '_python_build', '_sys_home', '_variable_rx', 'build_flags', 'customize_compiler', 'expand_makefile_vars', 
'get_config_h_filename', 'get_config_var', 'get_config_vars', 'get_makefile_filename', 'get_python_inc', 'get_python_lib', 'get_python_version', 'os', 'parse_config_h', 'parse_makefile', 'project_base', 'python_build', 're', 'sys']
OK

from distutils.sysconfig import get_python_lib>>> print(get_python_lib())

It will get you both dist-packages and site-packages folders. If the folder is not on Python's path, it won't be doing you much good anyway.

import sys; print [f for f in sys.path if f.endswith('packages')]
Output (Ubuntu installation):
['/home/username/.local/lib/python2.7/site-packages', '/usr/local/lib/python2.7/dist-packages', '/usr/lib/python2.7/dist-packages']
