Steps to replicate

I was working on a project after updating windows and I wanted to test my configuration so I did
> pipenv --rm to delete my current environment. When I tried to use > pipenv install --dev I got that error.
I have already tried reinstalling pipenv and python and deleting all my site-packages.

It once let me create an environment in c:\\users\\ale, but not in other directories. I also tried > pipenv -support, but it failed at getting the python installations with the same error as always.
I again tested removing the environment and performing a > pipenv install but this time it failed.

After some testing I removed the Pipfile and Pipfile.lock in c:\\users\\ale and >pipenv install worked again but only in that directory as creating an empty folder in the desktop or other directories and executing pipenv install always fails with the same traceback.

Can you help test if pep514tools works on your machine?

[alejmolinas]

Yes, pep514tools works on my machine

>>> import pep514tools as pt
>>> list(pt.findall())

These are not the same issue. Please fill out the full issue template.

I have a very similar issue using a fresh installed python 3.6 and also tried a fresh 3.7 on my windows 10 system:

I have no clue how to fix that.

[Pierek]

Anyone still having this problem in 2018.11.26 version? I'm performing the same steps as @alejmolinas

[govind-singh-repo]

@Pierek , I was facing almost the same error, It was caused due to reinstall of python (removal of other python versions). I just tweeked it by:

( replace C:\mapps\python3.8\ to where your python is located )

in file

C:\mapps\python3.8\Lib\site-packages\pipenv\vendor\pythonfinder\_vendor\pep514tools\_registry.py

change def getattr to by commenting the last return AttributeError ...

    def __getattr__(self, attr):
        if attr.startswith('_'):
            return object.__getattribute__(self, attr)

        if attr == 'value':
            attr = ''

        key = self._attr_to_key(attr)
        try:
            return self._d[key]
        except KeyError:
            pass
        except Exception:
            raise AttributeError(attr)
        print("Some error occured, continuing anyway ...", self._d, attr)
        # raise AttributeError(attr)

I guess we can revert the code back to original after single installation, since once I installed a pipenv the error was resolved
