Failed to start electron app using pnpm

Bug Description:

I'm using pnpm as package manager and an error occurs when starting electron app. I have checked that all extensions are using the same version and created a minimal reproduction, can anyone help me? Thanks in advance.

Steps to Reproduce:

1. checkout this repo
2. run pnpm i && pnpm start:electron

Additional Information

• Operating System: macOS 11.4
• Node Version: 16.15.0
• Theia Version: 1.32.0
• PNPM Version: 7.18.0

@holazz thank you for the discussion, we don't officially support pnpm as a package manager (we support yarn) but if you want to troubleshoot the error occurs when multiple versions of theia-extensions are being used.

With yarn we could perform:

$ yarn theia check:theia-version

or

$ yarn why @theia/core

To identify what extension(s) is/are being pulled at different versions.

Gotcha! Thank you for the detailed explanation.
