Operating System: Elementary OS Loki
Yarn version: 1.5.1
node version: 8.9.4

PROBLEM:
After update yarn to version 1.5.1, I can't install my project dependencies because yarn is not able to finish the installation process whereas if I use npm I don't have any problem.

The following message is always shown by yarn:

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

I don't know why but the registry response time is increasing.

Any help with this?

[telco2011]

I've checked with windows 10 environment as well and it happens the same situation. I can't use yarn to install my project dependencies.

[jschlieber]

Same probleme here....

[cwonrails]

Same issue.

[waptik]

is it a common problem for windows 10 users? 'cause i'm facing this same issue for some time now

[johpol]

Just want to add that I'm seeing this issue as well with Windows 10.

Try yarn config delete proxy - source

[waptik]

@wilfreddenton it didn't work for me.

[esetnik]

I have the same issue

[SEAPUNK]

yarnpkg registry is running really slow right now, occasionally erroring out with haproxy_service_unavailable

[esetnik]

Confirmed this is a npm outage https://status.npmjs.org/incidents/27bg84btqp7r

[jschlieber]

I don't think this issue is or was related to an npm outage...

[anilshrish]

This worked for me:

yarn install --pure-lockfile --proxy http://<proxy-address>:<port>

[azatakmyradov]

@anilshrish That worked for me, too. Thanks.
