Cannot compile components

[ilnur-slv]

I am trying to compile components using this documentation
https://docs.mathjax.org/en/latest/web/webpack.html

I do:
npm install
npm run compile
node .\components\bin\makeAll

I get a lot of errors:

Webpacking \src\a11y\assistive-mml
node:events:368
throw er; // Unhandled 'error' event
^
Error: spawn npx ENOENT

syscall: 'spawn npx',
path: 'npx',
spawnargs: [ 'webpack', '--json' ]
}
Command failed: node C:\Code\MathJax-src\components\bin\pack

I used different versions of node (10, 14, 16).

What am I doing wrong?

It looks like the call that is trying to run npx webpack is failing with a file-not-found error. It may be that npx isn't installed (it should be installed when you install npm, but I see some reports that it isn't with Windows). If you perform

npx webpack --version

does that give you an error message abut npx, or do you get the webpack version?

If you get an error, you may need to install that yourself via

npm install -g npx

See if that helps.
