I was trying to create a React app for my personal project, but then this error pops up whenever I'm in the middle of downloading react-dom. I see several people facing this issue, so I think this is a problem with npm itself. Please help us.

[PolybitRockzz]

I found a quick fix. Don't know why it worked, but if you're on Windows, fixing the problem is as simple as going to the Control Panel > Uninstall a program, then selecting Node.js and clicking Repair. It works!

[sunshu]

Update npm to the latest version fixed my question

[woody-li]

Same error, already repair Node.js.

I think we have many reports of the same so these should all be duplicates.

Afaik this is resolved by force-clearing the cache and upgrading / updating to the latest npm version.

Hi. thanks for this note it was helpful:

I'm not going to give you too many details basically because I will probably give you wrong or not related information but I solved this issue that in my case it was related with this specific package as a dependency: amplify-cli (npm intall --save amplify-cli)

This is what happened

• I removed the package.
• I upgrade npm
• I tried to install amplify-cli with save again then I got the ERR! cb() error

Details:

• I had installed this package before (as I said)
• I had installed this dependencies: graphql and ins>@types/grapthl</ins (I cannot tell if it was a mistake install those)
• I remove them, then ran npm install --save amplify-cli and the install worked fine (this package was the one giving me the ERR! cb() error message)

I understand this errors are specific, but maybe it could be helpful if this thing about @types/ is the problem

Important

Now I'm in a nightmare called Try npm install @types/graphql if it exists so take you time and think twice if you're gonna do that 🙅🏽 I cannot remember how did I solve this before

Solved

Jesus! that was horrible.. The only way I could solve that try to intall bulls~~ was restarting the container after npm install --save but I did it before without restart and it did not work.. I cannot imagine if it is a problem with VScode, angular, npm, cache.. you name it. Luck for me it was a container

[hamzakilic]

I got same error. and FIXED IT. I was trying to dockerize a nodejs project with a docker file. and package.json. on my ubuntu machine there is no problem, but on CI/CD machine (centos,debian) almost fails to dockerize

Tried Steps:

• clear node_modules
• updating node version
• updating npm version
• centos
• debian
• docker with different versions
• lots of configuration (npm install fetch-retries, timeouts ....)

My problem:

My problem was at TCP level. some of the TCP connections to registry.npmjs.org was returning RESET. with tcpdump I saw that if npm install fails cb() never called, I got TCP RESET packets from registry.npmjs.org ips. if npm install success, then no TCP RESET from registry.npmjs.org ips. I dont know why TCP RESET occurs. big network problem

My Solution: I putted registry.npmjs.org behind of an NGINX proxy on K8 and changed dockerfile npm install ====> npm install --strict-ssl=false (because nginx will return a default ssl)

docker build -t tag myproject --add-host registry.npmjs.org:nginxip . (redirect all npm install trafic to your nginx)

below is the sample K8 ingress

apiVersion: v1
kind: Namespace
metadata:
  name: gitlab
  labels:
    app.kubernetes.io/name: gitlab
    app.kubernetes.io/part-of: gitlab

apiVersion: v1

  name: npm-service

Hi! I got this error when I was running npm install node -v v14.16.0 npm -v 7.10.0

I solved this problem by updating my npm

[HomyeeKing]

the only suck thing I know is that the warning message of npm publish is indirect and not clear when you have not verify your email, just tell that they haven't verified the email, not something like security policy thing and package version problem...

Hello, I ma receiving this error while using WSL2 Ubuntu 20.04. I have installed node and npm via nvm. I am trying to run npx create-react-app projectname but I keep running into the issue. I am not sure what is causing it as I have the latest version of both npm and npx. Any assistance on this would be very helpful. Thanks.
