Informations

• Qiskit Aer version: master branch
• Python version: 3.12.0
• Operating system: Ubuntu 22.04.3

What is the current behavior?

I am just trying to install the library from the master branch in order to contribute with a PR, but this happens:

...
  error: subprocess-exited-with-error

  × python setup.py egg_info did not run successfully.

      To avoid accidental inclusion of unwanted files or directories,
      setuptools will not proceed with this build.

      If you are trying to create a single distribution with multiple packages
      on purpose, you should not rely on automatic discovery.
      Instead, consider the following options:

      1. set up custom discovery (`find` directive with `include` or `exclude`)
      2. use a `src-layout`
      3. explicitly set `py_modules` or `packages` with a list of names

      To find more information, look for "package discovery" on setuptools docs.
      [end of output]

  note: This error originates from a subprocess, and is likely not a problem with pip.

Steps to reproduce the problem

I am simply trying to build qiskit-aer from source following this guide. The step which fails is:

pip install -r requirements-dev.txt

and gives the output provided below. I also tried re-installing with:

 pip install --use-pep517 -r requirements-dev.txt

But this happens:

...
  error: subprocess-exited-with-error

  × Preparing metadata (pyproject.toml) did not run successfully.

What is the expected behavior?

I am expecting to have a clean installation of the developer dependencies.

Suggested solutions

Sincerly have no idea, I tried everything but the problem seems related to the code probably.

Same issue on Mac M2

hello, did you get any solution for this ? I am dealing with the same problem of installation

@Anoushka55 I didn't. Nobody answered to this issue right now.
