Shortly:
When I use “pip uninstall proto” to uninstall my module “proto”, an "AttributeError:‘EggMetadata’ object has no attribute ‘isdir’ "occurs.
Longly:
Just as the ex46 says, I create my own project named “prototype”, the directory tree is like below:
prototype/
bin/
hello.py
docs/
proto/
__init__.py
ex45a.py
ex45b.py
tests/
__init__.py
proto_test.py
setup.py
Notes: The ex45a.py and ex45b.py are the games I wrote in ex45 and they work well. The hello.py is just a print function with shebang line.
And the config in setup.py is:
config = {
'description': 'proto',
'author': 'andrew',
'url': 'URL to get it at.',
'download_url': 'Where to download it.',
'author_email': 'My email.',
'version': '0.3',
'install_requires': ['nose'],
'packages': ['proto'],
'scripts': ['bin/hello.py'],
'name': 'proto'
}
The test result is good. Then I use “python setup.py install” command in terminal, the proto module gets installed successfully and it will show up in the “pip list” command output.
However when I use “pip uninstall proto”, an AttributeError occurs as below:
It seems that the EggMetadata didn’t involve the location information so the “isdir” attribute is null.
While I searched in the documents, I find that in pip documentation v22.0.4:
pip is able to uninstall most installed packages. Known exceptions are:
* Pure distutils packages installed withpython setup.py install, which leave behind no metadata to determine what files were installed.
According to the distutils documents, my above “proto” module is exactly a pure distutils package, and I install it with “python setup.py install”, so I just can’t uninstall it with pip.
Here comes my question, how can you guys uninstall your module with pip since we do the similar things?
My environment:
Mac OS Montery v12.3.1; bashell; python3.7; distlib v0.3.4; pip v22.0.4; setuptools v60.10.0
