Problem with setting python extensions in vscode

I had written earlier, but didn't find how to fix this, i've tried to build in TOML cpython and PyO3:
1)cpython
Compiling cpython v0.6.0
error[E0425]: cannot find value PYTHONSYS_ENV_VAR in this scope C:\Users\2020.cargo\registry\src\github.com-1ecc6299db9ec823\cpython-0.6.0\build.rs:28:32

2)PyO3: Compiling pyo3 v0.13.2
error: failed to run custom build command for pyo3 v0.13.2

Caused by:
process didn't exit successfully: C:\Users\2020\RUSTprojects\trburcor\target\debug\build\pyo3-8786ed9dcaa55a08\build-script-build (exit code: 1)
--- stderr
Error: "Python 3.x interpreter not found"
The terminal process "C:\WINDOWS\System32\cmd.exe /d /c cargo build" terminated with exit code: 101.
These errors from vscode, what i've tried:
Created Py environment and run in terminal pypyint-env\Scripts\activate.bat
Then this work, but only in terminal.
Further I enter ctrl+shift+p -> python env-> choose one. Still error.
Tried in setting.json indicate path to py interpreter.Still error.
Cpython also as above you see...
