Vite gets stuck trying to resolve spdx-license-ids package during build

[praneetloke]

Hi, I am not sure if this is a bug with Vite or Rollup. spdx-license-ids and spdx-exceptions packages only provide JSON files, Vite hangs indefinitely after having failed module resolution for those packages. For example, I installed a package (@pulumi/pulumi) that installs spdx-license-ids transitively. Vite fails with:

[commonjs] Failed to resolve entry for package "spdx-license-ids". The package may have incorrect main/module/exports specified in its package.json.

The closest issue describing what I think is happening is #247. I added an index.js file that simply exports the index.json via module.exports in each of the offending packages locally in node_modules. Vite was then able to complete the build successfully. What is the right way to fix this? Should I open a bug report here?

Here's my env info:

Anyone?

Hello!

I hit the same issue, and the problem can be fixed by adding the "main" field to the package.json of the offending module. I have created some PRs to solve the problem.

jslicense/spdx-license-ids#29
jslicense/spdx-exceptions.json#8

For now it is possible to get around it by using my forks,

  "dependencies": {
    // ...
    "spdx-exceptions": "git+https://github.com/henriiik/spdx-exceptions.json.git",
    "spdx-license-ids": "git+https://github.com/henriiik/spdx-license-ids.git"
  },
  "overrides": {
    "spdx-exceptions": "$spdx-exceptions",
    "spdx-license-ids": "$spdx-license-ids"
  },

@henriiik thank you for creating those PRs! Also Happy New Year to you!

Hey! No problem! An update on this is that one of the PRs I made was closed since apparently it relies on a fallback in nodes module resolution algorithm. I have created an issue here in vite instead. #6350

if anybody is getting this error in webpack, ensure there's 'json' in resolve.extensions in your webpack config
eg.

 resolve: {
    extensions: ['.js', '.ts', '.jsx', '.tsx', '.css', '.json'],
  },
