Problems following "development of this repository" about simple

[otamachan]

Thanks for your feedback.
I fixed the README somehow.

But from your error message, it seems that setuptools is not installed.
Could you provide me the information about your development environment(OS, Python version)?

Also, I'm just wondering, how does this project track different ros-releases, melodic/noetic/etc?

Actually it does not track the ros releases. All the packages are built from source(github) specified by this yaml file. I keep it to point the latest versions as much as possible, but it's independent of ros releases.

Hi, sorry for the delay. We use pyenv to install our Python versions, and typically use Python 3.7.8 on Ubuntu Linux 18.04 or 20.04. I do not have setuptools installed, is that a requirement? Sorry, that's not true, I do have it installed:

$ pip install setuptools
Requirement already satisfied: setuptools in ./env/lib/python3.7/site-packages (50.3.0)

Following steps from git clone in a clean directory work for me (Ubuntu18.04, pyenv 1.2.15).
https://github.com/rospypi/simple#development
Could you try this and copy/paste the errors again?

git clone https://github.com/rospypi/simple.git
cd simple
git submodule update --init --recursive
pyenv local 3.7.5
virtualenv -p python3 dev
. ./dev/bin/activate
pip install --extra-index-url https://rospypi.github.io/simple/ -e rospy-builder/
rospy-build build -d any
rospy-build build -d linux --native
rospy-build index --local any --local linux index

ok, thanks, I found the problem. We don't use virtualenv, we use Python's built-in venv module.

this: python -m venv dev will result in the error I posted about above. When I switch to the virtualenv -p python3 dev command, it worked fine. I didn't have virtualenv installed, so I needed to add it. When I installed virtualenv, it worked fine.

Digging deeper, I found I could make it work with python -m venv dev, I think by uninstalling wheel and then reinstalling it with cache disabled:

pip uninstall wheel
pip install --upgrade --no-cache-dir wheel

So I guess unrelated to the repo, but its working now, thanks!

Ah I see. Thank you for your confirming!
