[resessh]

🐛 The bug
Requiring @nuxtjs/composition-api/package.json causes an error.

🛠️ To reproduce
Steps to reproduce the behavior:

1. Install nodejs >= 12.7.0 and @nuxtjs/composition-api@latest
2. Launch node
3. run require('@nuxtjs/composition-api/package.json')
4. See error

$ node
Welcome to Node.js v12.18.0.
Type ".help" for more information.
> require('@nuxtjs/composition-api/package.json')
Uncaught:
Error [ERR_PACKAGE_PATH_NOT_EXPORTED]: Package subpath './package.json' is not defined by "exports" in /Users/resessh/src/github.com/resessh/repro-error/node_modules/@nuxtjs/composition-api/package.json

🌈 Expected behaviour
No error

ℹ️ Additional context
https://github.com/nodejs/node/issues/33460 is relevant discussion over this issue. This behavior is very surprising and the workaround is to add package.json to exports.

@resessh Happy to add. Out of curiosity, what's your use-case?

[resessh]

@danielroe I'm sorry for lack of my use-case. This repo reproduce the problem I'm having trouble with.

There seems to be two problems. One is 'requiring package.json fails', and the other is 'no exports fields for nodejs' .

[resessh]

@danielroe I created a PR and it really solves this problem. Could you check it?

Let me know if that doesn't solve your issue.
