Can't build antlr4ng

[kaby76]

Just did a clone and trying to build antlr4ng. I'm getting a compilation error.

$ node --version
v21.7.1
03/15-08:23:49 ~/temp/antlr4ng
$ npm run build

> antlr4ng@3.0.3 build
> tsc && npm run build-cjs && npm run build-mjs

I have the latest of node and tsc for Windows 11.

I assume you have installed the dependencies. I see these errors when I have no node_modules folder.

I assume you have installed the dependencies.

What dependencies? Can you add to the project.json dependency tests or requirements so that the build can output what I need to install? Otherwise I have no clue. (Commenting out above source to get past compilation errors, I now get this.)

$ !npm
npm run build

> antlr4ng@3.0.3 build
> tsc && npm run build-cjs && npm run build-mjs

> antlr4ng@3.0.3 build-cjs
> npm run build-bundle -- --outfile=dist/index.cjs --format=cjs

> antlr4ng@3.0.3 build-bundle
> esbuild ./src/index.js --main-fields=module,main --bundle --target=esnext --keep-names --outfile=dist/index.cjs --format=cjs

'esbuild' is not recognized as an internal or external command,
operable program or batch file.

Right after cloning the repo run npm i in its root folder to install the dev dependencies. It's so common in TypeScript projects, I haven't documented that 🙂

[mike-lischke]

I have now added a chapter with the build instructions to the readme file.

Fixed with instructions in readme.
