Problems cloning MathJax-src repo

Created by: ghost

I am looking to clone the MathJax source repo and I am running into errors when compiling with TypeScript.

I ran npm install, npm update and tried updating Node and npm, but I still get the following errors when trying to run npm run install:

ts/a11y/sre-node.ts:25:15 - error TS2451: Cannot redeclare block-scoped variable 'require'.

25 declare const require: (name: string) => any; ~~~~~~~

../node_modules/@types/node/globals.d.ts:222:13 222 declare var require: NodeRequire; ~~~~~~~ 'require' was also declared here.

Found 4 errors.

npm ERR! code ELIFECYCLE npm ERR! errno 2 npm ERR! mathjax-full@3.0.1 compile: npx tsc npm ERR! Exit status 2 npm ERR! npm ERR! Failed at the mathjax-full@3.0.1 compile script. npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

The log file: 2020-02-26T21_05_03_551Z-debug.log

Since I believe that the current commit should most likely compile, I think I must have something wrong with my versions of TypeScript or whatever, but I already checked it using npx tsc -v and it was the same as listed in the devDependencies.

I would really appreciate some help here, since I am actually really keen on getting into MathJax and extending it for my purpose.
