Platformio-vscode-ide: Could not start PIO Home server: Error: timeout。

[chenjingyuanku]

When I upgraded to version 0.8.2, I was unable to open PIO HOME.
I removed %HOME_DIR%/.platformio/penv folder and restart IDE.
It's useless.
I have tried reinstalling, but it still prompts "Could not start PIO Home server: Error: timeout。"

Please open PIO IDE Terminal and type pio home, do you see any errors?

It seems that you have old version of Python in a system. Please navigate to OS Control Panel and remove ALL Python installation, then remove %HOME_DIR%/.platformio folder. Restart IDE.

The problem is solved，thank you so much!

Are there any other workarounds without removing other Python installations?

[ivankravets]

@withkittens
Please provide an output from system Terminal cmd

echo %PATH%
echo %PYTHONPATH%
python --version
pip --version
pip list

[withkittens]

%PATH%:

C:\ProgramData\Oracle\Java\javapath;
C:\Windows\system32;
C:\Windows;
C:\Windows\System32\Wbem;
C:\Windows\System32\WindowsPowerShell\v1.0\;
C:\Program Files\Git\cmd;
C:\Program Files\dotnet\;
C:\Program Files\Go\bin;
C:\Program Files\LLVM\bin;
C:\Program Files\CMake\bin;
C:\Program Files (x86)\GNU Tools ARM Embedded\7 2017-q4-major\bin;
C:\Program Files\GNU MCU Eclipse Windows Build Tools\bin;
C:\Users\withkittens\.cargo\bin;

%PYTHONPATH% is undefined. Thus, python and pip are not found (I've ran commands under Integrated Terminal of VS Code).

I do have an installed Python (3.6.2 under C:\dev\Python36) but it isn't in PATH.

This is an error in my case:

I will be happy to provide any other info that would be useful.

@withkittens I've just removed all Pythons from VM, install Python 3.6.4, then started PIO IDE and all works good.

Could you remove ALL Pythons, install Python 3.6 again and restart PIO IDE? Also, don't forget to remove "C:\Users\withkittens.platformio"
