Linker Error: failed to parse ESP-IDF/components/esp_event/linker.lf (VSC-237)

[armandr]

while I'm able to easily build and flash the hello_world sample from idf command prompt, the VS Code Extension gives the following error:

failed to parse C:/Users/r/esp/ESP-IDF/components/esp_event/linker.lf

This is a fresh install of VSCode, and the extension.

• OS Name & Version: Win 10
• VSCode Version: 2019
• ESP-IDF Version: 4.0
• Python Version: 3.7 (whichever is installed by the idf)

Additional context
prior to this, I was getting errors about missing python packages Pyserial and pyparsing. These are present when I open the IDF command prompt but not in a regular cmd.exe, so I pip installed them.

I don't think, that this error is related to the vscode plugin.
The cmake/ninja fails, not the handling of output.
Maybe you set some variable wrong

Please follow our issue template, which specify the necessary information we need to understand your issue.

Have you set up the extension following steps detailed in https://github.com/espressif/vscode-esp-idf-extension#how-to-use ?

Try to delete the build directory and build again, I dont know why, but it works!

[brianignacio5]

Since the error and information shown by the user doesn't seem to be an issue with ESP-IDF extension for Visual Studio Code, we are closing this.

Uninstall pyparsing and reinstall its version 2.2.0 will solve the problem
pip uninstall pyparsing
pip install pyparsing==2.2.0
There are a version conflict between the internal python at $HOME.espressif\python_env\idf4.2_py3.8_env\Scripts\python.exe and system's python
