Problem with exports

[pauldraper]

I'm not sure what the nature of the problem is, but the @rollup/pluginutils package won't resolve.

npm init
npm i @rollup/[email protected]

Node.js succeeds:

require.resolve('@rollup/pluginutils');

.../node_modules/@rollup/pluginutils/dist/cjs/index.js

enhanced-require fails:

require('enhanced-resolve').sync(process.cwd(), '@rollup/pluginutils');

Error: Package path . is not exported from package .../node_modules/@rollup/pluginutils (see exports field in .../node_modules/@rollup/pluginutils/package.json)

What is version? No exports https://github.com/rollup/rollup-pluginutils/blob/master/package.json

[pauldraper]

See install command; version is 3.1.0.

https://github.com/rollup/plugins/blob/master/packages/pluginutils/package.json

(And enhanced-resolve version is 5.8.3.)

[alexander-akait]

Oh, by default enhanced-resolve is loading only default or node conditionals (because we don't know nothing about esm/commonjs, because it is programmatic usage), but no default and no node in package.json, we strongly recommend always add default (but maybe out of scope your abilities), you can use:

require('enhanced-resolve').create.sync({ conditionNames: ["require", "node"] })(process.cwd(), '@rollup/pluginutils');

Excellent that worked. Thanks for the fast help!

I don't know enough to say what is "at fault" but for my case, I am looking to match Node.js require.resolve (I'm not bundling for a browser or anything).

The main problem when you use require.resolve Node.js known that you in commonjs, so can use require, but when you use programmatic API we don't known about it
