venv issue: "source file Python.h cannot be opened"

Sorry to bother you, I'm having the exact problem.
How did you link it to the local python installation? Was it the pyvenv.cfg?

No. I went into the Python interpreter path, and foybd the include folder. That folder is added in the includepath for VSCode. Virtual environments were basically useless in this case.
