Issue description

Running pipenv install --verbose failed.

Expected result

Expected a virtual env to be set up, a pipfile created, and no errors to pop up.

I'm getting the same error. Looking forward to someone smarter finding a resolution

jasoncammarata · 2020-06-01T00:10:58Z

I found a workaround, but I'm not good enough with computers/python/virtual environments to know why it works.
From Terminal:

Download virtualenv (if your pip install of pipenv didn't already)
Create a virtual environment in virtualenv --> look online for instructions
once inside the virtualenv go to the folder you want your pipfile
pipenv install [python_package]
Should create the pipfile and lock files. Then exit the virtual environment
Navigate to the folder for your project with pipenv files
type pipenv shell. This should create a virtual environment within the pipenv construct.

roshansivakumar · 2020-06-13T22:40:28Z

i've got the same error, anything to resolve it?
Though pipenv install in a created virtaulenv works with no issues like jasoncammarata mentioned.
Why is that?

vincentclaes · 2020-06-22T17:18:29Z

this issue still persists on win10 with python 3.8.3 and pipenv 2020.6.2

I have solved this by reverting to

pip install pipenv==2018.11.26

madnoh · 2020-07-12T10:15:50Z

Windows 10, Python 3.8.3, pipenv 2020.6.2

I managed to solve this by typing in the full path to the python.exe:

pipenv install --python="C:\Users\my_name\AppData\Local\Programs\Python\Python38\python.exe"

Viola! Virtual environment created.

leehanchung · 2020-07-17T04:19:36Z

Still getting the same error with full path to python.exe.

Windows 10, Build 20161
Miniconda Python 3.7.4
pipenv 2020.6.2

pipenv install --python="C:\Users\Han\Miniconda3\python.exe"

Pipfile:

[[source]]
name = "pypi"
url = "https://pypi.org/simple"
verify_ssl = true

[dev-packages]
pytest = "*"
v = {editable = true,version = "*"}

[packages]
numpy = "==1.19"
tensorflow = "==2.2"
pillow = "*"
requests = "*"
nltk = "*"
matplotlib = "*"

[requires]
python_version = "3.7"

Insigna2020 · 2020-07-24T13:36:29Z

I ended up having to specify Python version on pipfile in order to work with 3.8

[requires]
python_version = "3.8"

vijay532 · 2020-08-10T07:21:00Z

where is pipfile located ?

vijay532 · 2020-08-10T07:24:32Z

where is pipfile located ?

@vincentclaes thanks issues has been solved..

mracette · 2020-08-19T20:46:38Z

I am also seeing this error on OSX 10.14.6, with pipenv 2020.8.13:

Pipfile:

[requires]
python_version = "3.7.6"

pipenv install --dev --python $(pyenv root)/versions/3.7.6/bin/python

Finally,
AttributeError: 'NoneType' object has no attribute 'url'

sigtot · 2020-08-25T09:56:36Z

Did you ever find a solution to this @mracette ?

Edit: I had mracette's exact same error message, but was able to resolve it by reverting to pipenv==2018.11.26. It appeared in version pipenv==2020.4.1b1 which is the first release after the 2018 one.

mracette · 2020-08-25T14:18:11Z

@sigtot I also had to revert to 2018.11.26

ryanjdillon · 2020-10-01T12:46:09Z

@sigtot pip-tools and run of-the-mill venv? 😄

Zalarian · 2020-10-02T17:00:48Z

I am getting this too. Is there any specific reason as to why this is happening? Does it use the PATH / PYTHONPATH env variable?

I had multiple versions of python installed, along with trying out chocolatey and this error just appeared one day. Probably after I upgraded it. I went through, uninstalled every listed version of python, reinstalled 3.8.6 at system-level and still got this error. Uninstalled that and used chocolatey to install 3.8.6 and, yet again, still popped up.

I'm not sure if somehow my environment variables got messed up with the multiple versions and chocolatey, but I thought it would have been fixed with an uninstall/reinstall.

gaochuwuhan · 2020-10-03T13:00:41Z

I also got that error!!! Centos enviroment makes no sense as well.. have tried 2 computers under pipenv&pyenv,same message

dixanms · 2020-10-11T22:53:17Z

as others have stated, resolved downgrading to pipenv 2018.11.26_4

create file pipenv.rb with content of https://raw.githubusercontent.com/Homebrew/homebrew-core/fd7578b01f869570c0748a4e0ba54e064870e91d/Formula/pipenv.rb
run
brew uninstall pipenv
brew install ./pipenv.rb

ArunSharma93 · 2021-01-06T11:03:18Z

Running pip3 install pipenv==2018.11.26 in terminal solved the below issue for me

AttributeError: 'NoneType' object has no attribute 'url'

PatrikWiklund · 2021-01-22T15:30:23Z

I went in to "pythonfinder.py" where the error occurs, and commented out the sorting of the python version list. Felt comfortable doing it because of the comment.

So from:
# This list has already been mostly sorted on windows, we don't need to reverse it again path_list = sorted(versions, key=version_sort, reverse=True)

to:
# This list has already been mostly sorted on windows, we don't need to reverse it again # path_list = sorted(versions, key=version_sort, reverse=True) path_list = versions

This solved it for me.

Systemcluster · 2021-01-22T15:33:27Z

@PatrikWiklund I created a PR to filter out None results before the sorted call as well.

Cosmicoppai · 2021-02-24T14:54:02Z

This solved it for me.

After implementing above solution, I'm getting the Value Error "Unable to find t64.exe in package distlib"(despite the existence of t64.exe)

JadJabbour · 2021-03-28T14:17:37Z

run it with "--three"

pipenv --three

azmek · 2021-04-10T11:33:18Z

run it with "--three"

pipenv --three

Thanks JadJabbour
This worked for me
ex: pipenv --three install django~=3.1.0

screwt · 2021-06-22T07:08:12Z

Same error on win10 pipenv==2021.5.29 installing 2018.11.26 makes pipenv work as expected.

R30B · 2021-06-25T19:29:56Z

Same error i encountered but when i used pipenv --python 3.8 it worked.I hope it helps....

kevillion · 2021-07-07T19:51:02Z

Workaround for pipenv 2021.5.29:
specify your version of python when running pipenv for the first time:

pipenv --python 3.9.5
pipenv install

If you don't know your version of python:
python --version

All previous versions of pipenv appear to run as expected.

EudesSerpa · 2021-09-19T20:34:42Z

I solved it by adding: C:\Users\Username\AppData\Roaming\Python38\Scripts and C:\Users\Username\AppData\Roaming\Python38\site-package to environment variables.

georgik · 2021-11-03T08:53:43Z

The issue is still present in Windows Python 3.9.7 installed from Microsoft Store, pipenv, version 2021.5.29
@kevillion workaround solved the problem.
