Odd "MODULE_NOT_FOUND" out of nowhere

[deluca-mike]

slopp was working perfectly fine, then just did a reinstall/upgrade of another unrelated package with yarn, and now this:

$ yarn precompile
yarn run v1.22.10

$ solpp --no-flatten --defs configs/definitions.json --output eth/contracts/library.sol eth/pre-contracts/library.sol
internal/modules/cjs/loader.js:883
  throw err;
  ^

Error: Cannot find module 'antlr4/index'

Using node 14.15.1

npm install does seem to fix this. yarn install breaks it.

Despite solpp 0.11.2 specifying antlr4: ^4.7.1 yarn is pulling [email protected] which seems to have made changes that break solpp (in how it was being imported).

~~Will try upgrading yarn.~~

Confirmed. Installing solpp with yarn is busted. Use npm.

Thanks for flagging this. I pinned the version of antlr4 to ~4.8.0. Should be fixed in 0.11.3!
