Calling Setup.py in Ubuntu 20.04 does not work

[PythonQTMarlem]

Hello,

I have created a Setup.py file:

import os
import sys
from setuptools import setup


setup(name='PQT-Texteditor',
      version='1.0',
      description='Barrierefreier Texteditor der plattformunabhängig ist',
      author='Markus Lemcke',
      author_email='info@marlem-software.de',
      url='https://www.marlem-software.de',
      install_requires=['PyQt5'],
     )
	 
chmod +x setup.py
python3 setup.py install

I got the following error message:
error: can't create or remove files in install directory

The following error occurred while trying to add or remove files in the
installation directory:

[Errno 13] Permission denied: '/usr/local/lib/python3.8/dist-packages/test-easy-install-3247.write-test'

The installation directory you specified (via --install-dir, --prefix, or
the distutils default setting) was:

/usr/local/lib/python3.8/dist-packages/

Perhaps your account does not have write access to this directory? If the
installation directory is a system-owned directory, you may need to sign in
as the administrator or "root" account. If you do not have administrative
access to this machine, you may wish to choose a different installation
directory, preferably one that is listed in your PYTHONPATH environment
variable.

For information on other options, you may wish to consult the
documentation at:

https://setuptools.readthedocs.io/en/latest/easy_install.html

Question:
What does this error message say? What do I have to do so that I can run the setup.py file on Ubuntu?

@PythonQTMarlem
Just from reading what it says: you don't have permission to write into /usr/local/lib/python3.8/dist-packages/test-easy-install-3247.write-test. Either runs as a user who does and wishes to install there, or follow the suggestion of --install-dir ... to specify where you want it installed.

?

[PythonQTMarlem]

thank you.
This directory /usr/local/lib/python3.8/dist-packages/test-easy-install-3247.write-test can call:
/usr/local/lib/python3.9/dist-packages/test-easy-install-3247.write-test
/usr/local/lib/python4.0/dist-packages/test-easy-install-3247.write-test
and so on.

I think i have to look to --install-dir to define this in setup.py

@PythonQTMarlem Just to add to @JonB /usr/local is not writeable by non root users. If you want to install there you have to use sudo.

[PythonQTMarlem]

@jsulm Thank you.
You think: sudo python3 setup.py install
Right?
Do you know where I find Code Examples?

[jsulm]

@PythonQTMarlem Code examples for what?
To use sudo you just do

sudo ./Setup.py

[jsulm]

@PythonQTMarlem Yes, but python3 should not be necessery if you have

#!/usr/bin/env python3

as first line in setup.py and if setup.py is executable.

#!/usr/bin/env python3

sudo python3 setup.py install works. Thank you.

The #! / Usr / bin / env python3 doesn't always work. But that's the next topic I'm going to deal with.

Look forward to reading what you say about that not working :)

Executable bit not set? :-)
