User friendly error messages, when running subcommands (bin missing, access error etc) about args

[Siilwyn]

Hi @ntwcklng, just discovered args and I love the balance it strikes between features and simpleness. The implicit relation between the command definition and how the command binary file is called was the only confusing part for me. I think this will also be confusing for (potential) new contributors to a project using args. Instead of needing to npm link would you consider changing the command API to accept a path to the command? This would make the linking unnecessary and the relation explicit.

I don't understand, this is from package.json of lib catalog

  "bin": {
    "catalog": "dist/cli/bin/catalog.js",
    "catalog-start": "dist/cli/bin/catalog-start.js",
    "catalog-build": "dist/cli/bin/catalog-build.js"
  },

it uses args and this fails

$ ./node_modules/.bin/catalog build
/myproject/node_modules/args/lib/utils.js:317
      throw err;
Error: spawn catalog-build ENOENT

But if I had catalog build in scripts of package.json adn do npm run nameOfTheScript it will work.

as the lib has all this commands in bin section of packge.json all this binaries will be in ./node_modules/.bin/ so why can't args find catalog-build?

see interactivethings/catalog#408

Hey @safareli does this fix your problem: #46 (comment)

[safareli]

bin part of package.json is set up properly (see my last comment) not sure how npm link can help, as I just did npm i catalog and after it i expect running ./node_modules/.bin/catalog start to just work.

[ntwcklng]

Ah okay, i assumed you've pulled it from github for developing.
Why whould you run ./node_modules/.bin/catalog start instead of catalog start?

[safareli]

As it's installed locally as dependency of another project. so it's in package.json#dependencies and i do npm i and catalog is installed in ./node_modules/catalog and as it has bin in it's package.json there is also binary files in ./node_modules/.bin/.

[ntwcklng]

Can you share the repo or want to debug? Help is appreciated.

[safareli]

sure,

here you can see I have this script "start": "catalog start", If I do npm run start it works fine,
but if i do ./node_modules/.bin/catalog start it fails.
