Yarn - There appears to be trouble with your network connection. Retrying

问题

I have been trying to do the quickstart guide for react native, but kept getting this error

There appears to be trouble with your network connection. Retrying...

My connection works just fine.

回答1:

This happens when your network is too slow or the package being installed is too large, and Yarn just assumes it's a network problem. Try increasing Yarn network timeout:

yarn add <yourPackage> --network-timeout 100000

回答2:

I got this issue because I was working within my company internal network and proxy needed to be set.

$ yarn config set proxy http://my_company_proxy_url:port
$ yarn config set https-proxy http://localhost:3128

example $ yarn config set https-proxy http://proxy.abc.com:8080

Simple working solution (right way of doing it):

Looks like yarn was trying to connect via a proxy. The following worked for me:

npm config rm proxy
npm config rm https-proxy

回答4:

Could be that your network speed is too slow and timeout is relatively short, you can set yarn install --network-timeout=30000
If you still have the error, could be solved by proxy, vim ~/.yarnrc and add useful proxy setting.

回答5:

Turning off "real time protection" with windows defender fixed it for me.

Sucks but it appears the checks are too much for yarn to handle.

回答6:

Deleting the yarn.lock file and rerunning "yarn install" worked for me.

回答7:

Could be a proxy issue. Run the command below to delete the proxy.

yarn config delete proxy
