Is your package.json valid?

[theBstar]

@ljharb .Yes it is. Here is my package.json generated with npm init -y
{ "name": "rock", "version": "1.0.0", "description": "", "main": "index.js", "scripts": { "test": "echo \"Error: no test specified\" && exit 1" }, "keywords": [], "author": "", "license": "ISC" }

I am having the same issue when I try to create a new angular project using ng new, the console throws the error: Unexpected end of JSON input while parsing near ''

[bilel-tlili]

Im' facing the same problem, when i try to install any package it throws the error Unxpected end of JSON ....

[rajkumarGosavi]

Me too. I tried changing the registry and cleaning cache but none of it works

[bilel-tlili]

it was a network issue and now it's resolved by just connecting on another network

[theBstar]

Still facing the issue, where yarn just works fine.
Unexpected end of JSON input while parsing near '...\nwsFcBAEBCAAQBQJdik/' while installing yarn and babel

[jdmarshall]

I am setting up a proxy server trying to fix this issue for some of my coworkers with crap bandwidth while stuck at home. None of the commentary I can find anywhere has anything other than the workaround, which is to run:

npm run cache clean -f

which I highly suspect may be no more effective than "wait couple of minutes and try again"

[jdmarshall]

I notice that pacote has been substantially re-implemented, but hasn't been picked up yet by npm.
I'm curious if that would fix this problem.

npm 7 only ships with node 16 right?

That's a lot of people out in the cold for a very, very long time.

[ljharb]

@jdmarshall it also ships with node 15. But anyone with node 10+ can npm install -g npm

[jdmarshall]

I have to get every single one of my coworkers and the ops team to upgrade npm on every machine where our code runs, builds, or is developed. What 'anyone' can do is practically irrelevant in this kind of conversation. See also "you can use GC in C"... only if all of my coworkers and every library we use also agree to do it.
