Click on “Report a Problem”. It should auto-open a github issue text for you that contains the full stack trace. Either post a new issue with that window directly or post the output here. Otherwise we can’t tell what exact error you’re having.
Edit: The log is saying something about Python 2.5… This version is ancient. PlatformIO is supposed to install its own Python3 interpreter… maybe bootstrapping fails though. Do you really have Python 2.5 installed on your computer?
Thanks. I was able to install the PlatformIO extension now. I had some python 2.5 installation residues in my PATH variable and although the installer installs its own python, python seems like it has to be there before the python package is installed. So I think the installation process should be independent of python at all or it should be changed to work with all pythons that could be present on a system.
It cannot be demanded from a user to change his or her system configuration
just for installing the PlatformIO extension.
