Blockly version 8 won't compile with TypeScript without skipLibCheck

[Johnny Oshika]

I'm running Blockly in a headless environment and compiling my project with TypeScript. Since upgrading from blo...@6.20210701.0 to blo...@8.0.1, my project won't compile unless I ask my compiler to skip type checking all of my libraries by adding "skipLibCheck": true to my tsconfig.json.

Here's the error message:

If I add "skipLibCheck": true, then everything compiles fine, but then I lose type system accuracy with all of my other libraries.

I created a simple repository to demonstrate this problem: https://github.com/johnnyoshika/blockly-typescript-libcheck

How is everyone else overcoming this problem?

That screenshot of the error messages is hard to read, so here it is again:
