Pyinstaller can't find package importlib_metadata

I created a new poetry project.
main.py:
import importlib_metadata
PACKAGE_NAME = 'try_pyinstaller'
def get_version():
version = importlib_metadata.version(PACKAGE_NAME)
return version
def main():
version = get_version()
print(version)
if __name__ == "__main__":
main()
when I run pyinstaller with:
pyinstaller --onefile --name main try_pyinstaller\main.py --clean
i get the error:
C:\Users\micha\voltfang_software\tests\python\try_pyinstaller\dist>main.exe
Traceback (most recent call last):
File "importlib_metadata\__init__.py", line 381, in from_name
StopIteration
During handling of the above exception, another exception occurred:

importlib_metadata.PackageNotFoundError: No package metadata was found for try_pyinstaller
[2576] Failed to execute script 'main' due to unhandled exception!
The wierd thing is when I just change variable in version = importlib_metadata.version(PACKAGE_NAME) to version = importlib_metadata.version('try_pyinstaller') it works totally fine. Same environment, nothing else changed. Just put the hardcoded string in.
is this a bug or am I doing something wrong?

The answer to this question can be found here:
https://github.com/pyinstaller/pyinstaller/issues/7399
In short:
If you use importlib_metadata.version('try_pyinstaller'), PyInstaller's bytecode scanning can infer that metadata for try_pyinstaller needs to be collected. If you use a variant with non-literal argument, importlib_metadata.version(PACKAGE_NAME), it cannot do that, and you need to explicitly instruct it to collect metadata via --copy-metadata try_pyinstaller.

Need help installing pyrate for Python on Windows 10, getting error message

I need help installing pyrate. I have Windows 10 and installed python 3.9.2 and am trying to install pyrate by following the instructions from:
https://github.com/mess42/pyrate
I have followed the install instructions up until the fourth and final command, which is 'pip install [-e] .'. After entering the command I get the following error message:

Can someone please help. Thanks.

You need to type either
pip install .
or
pip install -e .

-e means edit mode,
and it is optional that's why it is written in square brackets as [-e].
If you want to edit the module as you use pip install -e . otherwise go for pip install .

Some python packages require other ways, for example, the POT package requires a specific C++ compiler to install. Make sure you read the entire instructions and have everything you need. Another thing that works for me if you have all the requirements and you are running Linux like me, you can just simply lead your terminal to where the file is and just run for example python package.py and it installs. Hopefully, this helped you and you can install your package.

Python external on Azure ImportError No Module Found

If i locally run my code with python main.py, then this error occurs locally. If i run it with python3 main.py, it works as expected. I suspect my azure app service is not running the correct version of python, however, it is set to python 3.4

UPDATE
So I went to the debug console in kudo and i ran python
-m pip install --upgrade -r d:\home\site\wwwroot\requirements.txt.
Here is the error
ERROR: b"'xslt-config' is not recognized as an internal or external command,\r\noperable program or batch file.\r\n" ** make sure the development packages of libxml2 and libxslt are installed ** Using build configuration of libxslt
One of the requirements is Pillow which requires libxml2 and libxslt. I've tried using wheels however, I've had no success.
UPDATE II
I tried to install virtualenv since it does not exist and I receive a permissions error.
UPDATE III
I ran this command
D:\home\python364x64>python -m pip install newspaper3k
I test everything locally, and it works perfect. I push and receive this error below.

Per my experience, we have no permission to modify D:\home environment.
So , It's better to use python extension. Please follow the steps in this case: Azure Flask Routes Not found and use command python -m pip install newspaper to install additional packages in python extension.
Please make sure the package you want to install must match with version of python extension. Otherwise, it will throw error as follows.
Hope it helps you.

Install Pyicu in python 3.x

How can I resolve this? Help me pls.

You can download a corresponding whl file from Unofficial Windows Binaries for Python Extension Packages
For example, the latest version (as of Jan 13 2019) for your 64-bit Windows and Python3.7 version is PyICU‑2.2‑cp37‑cp37m‑win_amd64.whl
Then open the Windows Powershell console as Administrator, cd to the directory where you put the whl file and execute the following command:
python -m pip install .\PyICU‑2.2‑cp37‑cp37m‑win_amd64.whl
or (if you already have a previous PyICU version installed)
python -m pip install -U .\PyICU‑2.2‑cp37‑cp37m‑win_amd64.whl

For the record:
My system (Win 10, 64 bit, python 3.8) gave me the exact same error message.
The solution was to install the 32-bit version of the PyICU whl file, not the 64 bit version.
