buildozer master cannot work from within venv / bootstrap ios-deploy fails because of nested virtualenv when trying to install pure-Python dependencies.

[cederom]

Versions

• Python: 3.11.9.
• OS: macOS 14.5 Sonoma ARM64.
• Buildozer: bd1d530fbe1e7f025a2085947f2fa5cf8ba15f40 (master).
• kivy-ios: master and v2024.03.17.
• ios-deploy: master and 1.12.2.

Description

• Buildozer release 1.5.0 (2023-01-28) can work from within virtualenv.
• Buildozer master cannot work from within virtualenv (fails at ios-deploy dependencies bootstrap).
• No matter if ios-deploy and kivy-ios uses release or master.
• Please run buildozer outside of a virtualenv instead is not possible on all platforms where package is not available or system modification is not possible.
• This is a serious regression.

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by switching back to a branch.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -c with the switch command. Example:

  git switch -c <new-branch-name>

Or undo this operation with:

  git switch -
