@freakboy3742: This was caused by the environment variable PIP_REQUIRE_VIRTUALENV, which I guess you have in your shell startup files. Chaquopy passes pip the --isolated option to make it ignore environment variables, but this doesn't get passed through to the recursive copy of pip that's used to build PEP 517 environments.

In this case you do appear to be in a virtual environment, but my guess is that when you started the Gradle daemon, you were in a different environment with a different version of Python. On macOS at least, subsequent invocations of Gradle don't update the daemon's environment (gradle/gradle#12905 and gradle/gradle#10483). So when you did this build with Python 3.10, it located the python3.10 executable using your original PATH, which is the copy in /Library/Frameworks, not in your virtual env.

The fix is to pass through the --isolated option to the recursive pip process. This is definitely a candidate for submitting to upstream pip.

[freakboy3742]

Nice catch. Your analysis of my setup is dead on - I have PIP_REQUIRES_VIRTUALENV in my .zshrc, and when I hit this problem, I was moving between projects, so the virtual environment was different. A Python version change between projects is entirely probable, although I can't recall the specifics.

Creating a new venv worked for me. While activated, I saw the same activation requirement error. Since recreating worked, I will blame renaming the venv directory after init for pip's failure to detect the venv.

As the venv documentation says, venvs are "Not considered as movable or copyable" – or renamable.
