git dependencies in pip don't install on Windows

Open johnc44 opened this issue 7 years ago • 4 comments

Description

I'm not able to use git/ssh based dependencies using PIP and SAM.

Using a git dependency in my requirements.txt file like this: git+ssh://[email protected]/myaccount/example.git

When running sam build from a Windows command prompt, it gives an error like thi: AssertionError: name 'c:\users\johnc\appdata\local\temp\pip-req-build-puwxrmxy\.git' doesn't start with prefix 'c:\users\johnc\appdata\local\temp\pip-req-build-puwxrmxy\'

Steps to reproduce

From a Windows 10 command prompt:

  1. sam init -r python3.6 -n git-dependencies
  2. Edit requirements.txt and add in a git dependency: git+ssh://[email protected]/myaccount/somethingorother.git
  3. sam build

Observed result

Expected result

Should have installed dependency from git.

Additional environment details (Ex: Windows, Mac, Amazon Linux etc)

  1. OS: Windows 10
  2. sam --version:0.15.0
  3. python version: 3.6.7
  4. pip version: 19.0.3

If I run from Ubuntu WSL then it installs OK. (But not if I use "--use-container", but then that never works for me from WSL anyway).

It also doesn't work from Windows if I add "--use-container" in which case I get:

Error: PythonPipBuilder:ResolveDependencies - Command "git clone -q ssh://[email protected]/myaccount/sample.git /tmp/pip-req-build-1n5kwnr1" failed with error code 128 in None

Is doing this sort of thing supported with "--use-container"? (If not, I can maybe raise it as a feature request)

From Windows, installing using pip directly works, i.e. like this: pip install -r src\requirements.txt -t .aws-sam\tests

So I know that the requirements file is good, and that Windows, git and pip are playing nicely together.

this is definitely frustrating and is something we need to look into. But as a workaround i would suggest building a wheel of your git dependency locally, and sticking it in your requirements.txt.

sriram-mv avatar Apr 24 '19 16:04 sriram-mv

Thanks, @TheSriram for the reply. Sorry it took me so long to respond, but I needed to find time to play about with your suggestion.

Am I right in thinking that you are proposing:

  • Build my package as a wheel
  • Copy the wheel alongside my lambda
  • Add a relative path to the wheel in requirements.txt.

I tried this. My setup is something like:

mylambda
    packages/samplelibrary-1.0-py3-none-any.whl
    src/
        requirements.txt (containing one line: "packages/samplelibrary-1.0-py3-none-any.whl")
        main.py
    template.yml

This does work OK if I use "sam build". However, it does not work if I use "sam build --use-container". I also tried moving the packages into "src" but that also doesn't work with --use-container because the relative path is based on where I run the command from, not relative to requirements.txt. (Not that I particularly want to do it that way anyway).

At the moment, I don't need --use-container but I don't want to start building things that won't work with it because we might find at some point that we do start using a dependency that needs to be built that way.

Digging around in the error some more, it does look like this is a pip problem.

pip download -r requirements.txt --dest temp - this throws the same error as I described above.

However, pip install -r requirements.txt --dest temp - this works fine.

I'll be honest, I've never used pip download so not sure why one should work and not the other.

(Found pip issue: https://github.com/pypa/pip/pull/6436)

This should fix half of the issue, but won't address the problem of it not working with "--use-container".

johnc44 avatar Apr 30 '19 09:04 johnc44

Having same issue. Would be interested if there was a work around. We do use the --use-container flag
