I tried to install a package with yarn earlier today and I got this

yarn install
yarn install v1.9.4

does anybody know how to fix this? My network seems to be okay, not slow at all.

It happens with every package I tried.

}

Also a quick note: npm i works fine - only yarn is having issues

I had the same issue and solved by following steps:

Run the terminal command

  1. Clean npm cache
  2. npm cache clean --force
  3. set http_proxy=
  4. Set https_proxy=
  5. Yarn config delete proxy
  6. Npm config rm https-proxy
  7. Npm config rm proxy
  8. Restart your terminal
  9. yarn
  10. Yarn –network-timeout 100000

Restart your terminal.

it worked for me.

If you are using WSL for linux just add the current ip domain in: C:\Windows\System32\drivers\etc\hosts e.g:

104.16.21.35    registry.yarnpkg.com

i had a different error, but the same network connection issue. i read through this thread: https://github.com/yarnpkg/yarn/issues/15

and ended up uninstalling/reinstalling node/npm which fixed my issue. maybe there's something wrong with your node installation too?

It may be the library was originally using npm instead of yarn. In my case I had to install everything with npm instead of yarn. I removed the yarn.lock file and then:

npm install

proxy in bash env caused my same problem.

after running cmd unset HTTP_PROXY HTTPS_PROXY ALL_PROXY, fixed this problem.

I got this as well.

I ran yarn install --no-lockfile and it worked, so I deleted the node modules again and deleted yarn.lock. It looks like a bug in yarn, because yarn wasn't having issues in previous versions of my application.

I had the same network retrying issue when I used yarn install, simply using yarn worked for me.

I have tried a lot:

  • npm clean cache
  • yarn clean cache
  • yarn config delete proxy
  • yarn config delete https-proxy
  • yarn config delete registry
  • yarn install --network-timeout 1000000

finally it works!

In my case, there was a hidden file .npmrc that had the registry pointed to a location in another private network, which my network did not have access to. Once, I commented out the private network related entries in this file, yarn install started working. Also, yarn-error.log was generated, that had this information.

here's what worked for me:

brew reinstall node

brew reinstall yarn

npm cache clean --force
 && yarn cache clean
 && yarn config delete proxy
 && yarn config delete https-proxy
 && yarn config delete registry

then RESTART immediately.

retrying few times worked out for me on similar issue.

Check your internet speed / strength of connection. I had this problem while I was on a spotty public wifi. Noticed that it was a different package that threw the error each time I tried. And once I got faster / more stable internet this problem went away. (The packages were too large for my poor connection).

The below worked for me

Set following values on terminal

set http_proxy=

set https_proxy=

I had a similar problem when building in node container. Not exactly as in question, but probably it will help someone. Option --network=host was the solution in my case.

docker build --network=host --progress=plain .

yarn install --network-timeout 1000000

is not useful for me.


but when i use this command

npm config rm proxy 
npm config rm https-proxy

solve my issue

it worked!
