🐞 Problem

In the contributor guide here, the flit command (flit install --symlink) doesn't work on my machine and get a strange error.

Traceback

💡 Possible solutions

  • Following this particular error message from the traceback, it seems that pyproject.toml has ipywidgets versions mentioned twice in the same file. I am not sure if this causes a problem but removing any one of them solves the error.
ERROR: Double requirement given: ipywidgets>=7.0 (from -r /tmp/tmpagk2oy8crequirements.txt (line 20)) (already in ipywidgets>=7.6 (from -r /tmp/tmpagk2oy8crequirements.txt (line 2)), name='ipywidgets')
  • Using flit install --symlink --deps=develop also fixes the error without changing pyproject.toml.

So something similar might be needed? I am not sure if this is really an issue for its just on my machine so just wanted to report it here.

Thanks!

I see that we are giving inconsistent versions for ipywidgets. This fixes the issue:

$ git diff
diff --git a/pyproject.toml b/pyproject.toml
index 06875342..4e6cd073 100644
--- a/pyproject.toml
+++ b/pyproject.toml

     "isort",
     "jupyter-client",
     "jupytext",

marking it as easy :) Any newcomer, please go ahead and make a pull request directly, no need to ask for permission.
