Pipfile.lock contains \u0000 characters and installation fails

[BramVanroy]

Issue description

Installing a pipenv based on a requirements.txt file (below) in Python 3.6.4 (also tried 3.6.7) on Windows 10 64x fails. Upon investigation it seems something goes wrong with the hashes where the first hash is a sequence of \u0000.

Expected result

A successful installation.

Actual result

Traceback (most recent call last):

pip: error: Arguments to --hash must be a hash name followed by a value, like --hash=sha256:abcde...

When investigating the Pipfile.lock, I found that the first hash is just a sequence of \u0000 (full file below in the logs):

"kiwisolver": {
            "hashes": [
                "\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000",

                 ...
            ]
}

Trying pipenv lock --clear did not solve the issue. This also happened with the packages pandocfilters and send2trash. I even tried a full Python reinstallation.

Steps to replicate

Using Python 3.6.4 as a base, install the following requirements.txt file:

opencv-python
jupyter
matplotlib
pandas
numpy
pillow
scipy
tqdm
scikit-learn
scikit-image
seaborn
h5py
ipykernel
bokeh
pickleshare

Both for Powershell and CMD I get

Active code page: 850

But to be honest I have no idea what that means.

I'm also having this issue. I create a fresh virtual environment using python 3.6 under Anaconda distribution, latest version of pipenv, and then when I try to install django I get the similar result when attempting:

pipenv install django

I get the following error:

after doing so, I get an error installing pytz package dependency due to an incorrect has value, inspecting the hash in the pipfile lock and it's the following:

I've tried all the same things.

Have you figured this out since your last posting?

[BramVanroy]

@nkabram No, I never found a fix for this, unfortunately. It is a very prominent issue especially when installing files from URLs rather than PyPi. (E.g. CUDA specific versions of a package such as torch.)

[BramVanroy]

From what I have tested, #3298 fixes this. I tried this on two different Windows 10 machines with Python 3.6 and 3.7, installing the requirements.txt from the OP as well as installing other hardware-specific packages and that seems to work fine now. (Locking is still very slow, though.)

Side note: I think that in-between when the problem first started (OP) and today, I may have updated pip. In any case, the issue seems solved for pip 19.0.3 and pipenv 2018.11.27.dev0.

A colleague of mine is hitting the same issue simply installing flask with pipenv on windows.

pipenv install flask

but no errors happens on my computer (with the same hardware, same environment)

We both have pip-19.1.1 and pipenv-2018.11.26 (lastest on pypy).

There is a release plan for a fixed version of pipenv ?

Are you also on Windows? Is the default encoding the same for both systems? I have a feeling that this can be the issue.

As you can see in the post before yours, the problem was fixed in a recent branch ere on Github. Pypi lags behind a bit, so try installing from source.

[webartoli]

We are both on windows, and we have the same default encoding on Windows Os and Python.

In the next days we will try to install pipenv from source in the host that is showing the issue

Installing pipenv from source I'm hitting different problem.
