Installation with pip in Python 3.9 - cppcheck_junit is not recognized as an internal or external command, operable program or batch file about cppcheck-junit

[johnthagen]

Edit: I am using the global py launcher that is installed by default on Windows. It is a convenient way to use multiple Python versions without having to worry about which program is python in the path: https://www.python.org/dev/peps/pep-0397/. If python is correctly pointing to Python 3, you could also run python -m venv venv as the first step below.

@ncook-hxgn cppcheck_junit uses setuptools to install a console entry point into the Python environment in which it is installed. I think perhaps that the way you installed it on Windows with --user perhaps didn't get it into Windows PATH. I've not tried installing this globally on Windows before like this.

A good practice is to use virtual environments: https://docs.python.org/3/tutorial/venv.html

Please try this:

> py -m venv venv
> venv\Scripts\activate
(venv) > python -m pip install --upgrade pip
(venv) > python -m pip install cppcheck_junit
(venv) > cppcheck_junit --help
usage: cppcheck_junit [-h] input_file output_file

Converts Cppcheck XML version 2 to JUnit XML format.
Usage:
	$ cppcheck --xml-version=2 --enable=all . 2> cppcheck-result.xml
	$ cppcheck_junit cppcheck-result.xml cppcheck-junit.xml

positional arguments:
  input_file   Cppcheck XML version 2 stderr file.
  output_file  JUnit XML output file.

optional arguments:
  -h, --help   show this help message and exit

Whenever you have that venv virtual environment activated the cppcheck_junit tool will be in the PATH. This also keeps cppcheck_junit isolated from other tools you may want to install in the future.

@johnthagen it works perfectly when installed from 3.9's pip, when there's no cruft from a previous attempt in Python 2.x.

I will look into venv, I think it will probably save us a lot of headaches. I've avoided it for now because there's not a great need for it my this particular case, but it's something I think I need to know about and I can see how it would save me some hassle in the future - thank you for enlightening me to that :)

Further, I see the python file, but no .bat or .cmd wrapper. Possibly this is just a documentation issue..

C:\>where /R C:\python39 cppcheck_junit
C:\Python39\Lib\site-packages\cppcheck_junit.py

C:\>

Indeed, using the full path to cppcheck_junit.py works - 🥳 - but this is a little unwieldy. Possibly pip should have put site-packages on the path. Is this a pip bug/config error?

New machine: installed Visual Studio's Python 3.9 and no other pythons. No Pip. (╯°□°）╯︵ ┻━┻

OK I guess I will install Python like a normal person 😁
