Error ... Cannot find package 'visitor-as'

[mattjohnsonpint]

Steps to reproduce:

• In a new empty directory, create a new AssemblyScript project .
• Run npm run asbuild - it should compile without error
• Run npm install json-as
• Modify asconfig.json to add "transform": ["json-as/transform"] to the existing options section
• Run npm run asbuild again - it fails with:

Tried manually installing with npm install visitor-as --save-dev, but that gives:

It does work if I use --force, but I shouldn't have to do that.

Not sure if this is a problem with as-json, or with visitor-as, or both.

Thanks.

To clarify, if I use --force or --legacy-peer-deps, it adds visitor-as to the devDependencies section correctly, but future calls to npm install (such as on a fresh clone of my project repo) still fail with the same message.

As a workaround, this seems to do the trick:

{
 "dependencies": {
     "json-as": "^0.5.65"
  },
  "devDependencies": {
    "assemblyscript": "^0.27.14",
    "visitor-as": "^0.11.4"
  },
  "overrides": {
    "assemblyscript": "$assemblyscript"
  }
}

With that override, now my npm install works without giving an error.

Got it. Yeah that's just how NPM works sometimes and is a problem with visitor-as' deps

[JairusSW]

Resolved. Json-as now ships with its own visitor
