tool.poetry.dependencies -> from github fails with runtimeError

[MisterBianco]

• I am on the latest Poetry version.

• I have searched the issues of this repo and believe that this is not a duplicate.

• If an exception occurs when executing a command, I executed it again in debug mode (-vvv option).

• Kali linux: Linux kali 4.18.0-kali2-amd64 Add support for private indices #1 SMP Debian 4.18.10-2kali1 (2018-10-09) x86_64 GNU/Linux

• Poetry version: 12.10

[tool.poetry.dependencies]
python = "^3.7"
toml = "^0.9"
scapy = {git="https://github.com/secdev/scapy.git", branch = "master" }

Issue

After a really long hang at:

Virtualenv boop-py3.7 already exists.

[MisterBianco]

If I change scapy to:

scapy = {version="^2.4"}

It works as expected, but I need the master branch for a recent commit...

Unfortunately, there is no way for Poetry to retrieve the version of the package from this line: https://github.com/secdev/scapy/blob/master/setup.py#L58

Poetry tries its best to retrieve the information it needs but sometimes it's just not possible without executing the setup.py which Poetry tries to do by executing python setup.py egg_info but it seems to fail for you, likely because setuptools does not exist in your virtualenv, and thus Poetry falls back on AST parsing.

I think if you do poetry run pip install setuptools before trying to install again it should work.

[MisterBianco]

I guess I will chuck it up to an issue with scapys setup file and call this resolved. I shall just wait for them to do a release. Thanks

I installed setuptools by poetry add --dev setuptools, but this error still happens. Problem is this line

pytype = { git = "https://github.com/google/pytype.git", branch = "master" }
