vscode-ccls does not compile

I am trying to compile a local version of vscode-ccls by downloading the git repo. I tried the following:

$ git clone https://github.com/MaskRay/vscode-ccls.git $ cd vscode-ccls $ npm install $ npm run build

Exepcted behavior: the extension successfully compiles

Actual behavior: I get the following errors:

$ npm run compile

> ccls@0.1.29 compile
> npx tsc -p ./

Found 12 errors.

I get the same errors if I just open up vscode in the cloned repo and pressing (per the instructions at https://github.com/MaskRay/ccls/wiki/Visual-Studio-Code)

Versions of tools I am using:

$ npm -v
8.6.0

$ node -v
v16.14.2

$ code -v
1.66.1
8dfae7a5cd50421d10cd99cb873990460525a898
x64

I can see how to fix most of these errors by changing the imports, but I wanted to make sure I am not doing anything wrong.
