Pipenv: Unable to install package in container

[sijis]

I was troubleshooting an opened bug (https://github.com/pypa/pipenv/issues/1639) that I seem to have run into. In trying to reproduce it, it seems like i bumped into another issue.

This looks similar to the closed https://github.com/pypa/pipenv/issues/1441 issue, however, the command virtualenv --python=python3 myenv did not error out as anticipated in the comments.

Expected result

I expected to see a Pipfile and Pipfile.lock in the /tmp/test1 directory.

Actual result

Saw the strack trace above.

Well, i know one way to solve this.

[sijis]

Don't use Docker? :)

I got past the initial error hacking this:

         self.write_toml(data, 'Pipfile')

Now i'm trying to bypass the next hurdle

My suspicion is that there assumptions that python and pip will be available but that may not be necessarily the case.

[kennethreitz42]

can you try again with the latest version?

[kennethreitz42]

pip and virtualenv should always be available within a virtualenv, yes.

Why is “virtualenv location” empty?

It still seems to hold true. The Virtualenv location: is still blank. However, i noticed a slight difference in error depending on where i execute python3 -m pipenv ....

To add. I do not get the error and everything succeeds if i also install python2 dnf install python2.

[kennethreitz42]

We fixed this in the most recent release.

[techalchemy]

I know what’s up here

[techalchemy]

@sijis can you try installing pipenv from pip install -e git+https://github.com/pypa/pipenv.git@bugfix/venv-location#egg=pipenv

[sijis]

That worked!

I did do pip3 vs pip in the command you provided.

Hopefully I'm not hijacking this issue, but I think the case where a Pipfile needs to be created has a problem.

[techalchemy]

don't use --system to create pipfiles, dependency graphs can only be resolved in an isolated environment

[techalchemy]

also don't use --system to install single packages, this is meant to be disabled but is accidentally allowed

[darkfeline]

Should there be a release before closing this bug? As I understand it, the final bug fix has not been released yet, although it has been submitted.

[techalchemy]

@darkfeline thanks for your comment, our source control workflow follows a pretty standard workflow. Fix gets merged, issue gets closed. Issue closure isn't tied to release schedule.

[cmac4603]

I am still seeing this issue on python:3.6 docker. Is there a fix released, or a quick fix a user can do?

I am tring to install dependencies, but even a pipenv shell from fresh doesn't seem to work for me.

[techalchemy]

@cmac4603 you can't run pipenv shell before you've ever installed anything. I don't see how your issue relates to this one, please either include all relevant details or open a new issue.

[cmac4603]

I think I actually have a vague idea why this is happening. It is basically the same as the /bin/python path problem, and is probably related to system encoding. I don’t have any interest in digging into this, however, as I do not use Docker at all. I can probably point you where to look if anyone is interested. Just hit me with an email of ping me on PySlackers.

looks to me like the issue is that you are trying to do this from / and you never made an app directory which breaks things, we just need a better error message

Can you explain exactly what the resolution here is supposed to be? I tried adding

WORKDIR /app/ into my dockerfile, but when I tried to install the dependencies with pipenv using a requirements.txt file, it said the folder was not found.

Here's what my folder set up is:

rlittles@rlittles-linux1 (/home/rlittles/git_projects/pixel-mask-gen) (158018408-automate-bad-pixel-mask-generation) $ tree

├── test
│   ├── __init__.py
│   └── test_script.py
└── TODO.md

and here's my Dockerfile:

FROM python:3

WORKDIR /app/

ADD script.py /

RUN pip install pipenv

RUN pipenv --three

RUN pipenv install -r app/requirements.txt

CMD ["pipenv", "run", "python3", "app/script.py", "app/config.yml"]

The way I run my script locally is just python3 script.py config.yml, and my dependencies are stored in the requirements.txt file. How do I follow your instructions to be able to:
1) Initialize a virtual environment in Python using pipenv
2) Install the already-defined dependencies listed in requirements.txt

so that I can use pipenv to execute my Python script in the virtual environment.

Thanks in advance.

In docker containers, you are not intended to deploy a requirements.txt file or to use a virtual environment. Since a docker container is an isolated environment itself, you no longer need the extra layer of isolation.

You need to start by converting your requirements.txt to a pipenv environment locally in order to generate a Pipfile.lock -- please see the documentation.

Based on the Dockerfile it seems like you are just getting started with both docker and pipenv at the same time -- you need to ADD each file that will be needed in the docker container, including a Pipfile.lock and your entire application. See the docker documentation for help on docker keywords, but you'll need to find a tutorial on deploying python applications in docker containers for more general guidance.

The WORKDIR command changes your directory inside the container. so if you then pipenv install -r app/<something> when you have already set WORKDIR /app/ you are not likely to be successful, since you are asking pipenv to install /app/app/<something>.

Once you have docker and pipenv working independently, you should then read pipenv documentation on deploying system dependencies which includes a bit of information about what you want to pass inside a docker environment.

Thanks for being patient and giving a thorough explanation! I was able to get my Docker file running correctly independent of pipenv. Unfortunately I am not able to use pipenv locally due to issue #2125 but that is a separate topic and so I will not address it on this thread.

I'll make sure to review the documentation for docker that you recommended, and thanks again for the help.
