Yarn add hangs building fresh packages for Puppeteer

[Srutherford2407]

Yarn Version 11.12.3

Bug with package install. Running yarn add puppeteer and it hangs on fresh package install never finishing. This is the only package I am having an issue currently.

Run yarn add puppeteer

What is the expected behavior?
Package should install, I need this package for QA UI automation on a project

Please mention your node.js, yarn and operating system version.
Node version 10.13.0 running on a Mac

I installed the same package on OSX Sierra, Node 10.13.0, Yarn 1.12.3 and it worked for me.
It was slow though... it took ~25 seconds on a Macbook Pro i7.

That step is running puppeteer's custom install script, so it might not be completely up to yarn.

---

I think you could check the output by running this script manually by running:

yarn add puppeteer --ignore-scripts
cd node_modules/puppeteer
yarn exec node install.js

It looks like it actually downloads Chromium, so if that download hangs for some reason, then it could hang all of the yarn install.

It is so slow today, every time I run yarn install or yarn add some-package in my monorepo I have to wait about 5 minutes...

Would be nice to show this progress during yarn add or yarn install

What Building fresh packages doing ? Can I get the info about time spending like --har options ? It takes really long time in my project, like hundreds seconds .

Besides making there be a clearer indicator of the download, it would also be nice if it better cached the download - i noticed when I was on a slow internet connection earlier today that every time I ran yarn install without updating the puppeteer version, it still took forever to run that build script; if it's really just downloading Chromium then I'd expect that that download would be cached. But maybe that's an issue for the puppeteer repo.

I've encountered this issue - installed Chromium manually (outside of the terminal). Then I've run it again and it's now stuck at this -

installed Chromium manually (outside of the terminal)

This doesn't matter. puppeteer will always download chromium on it's own, since it cannot know where to look for a locally installed version 🤷‍♂️

$ yarn exec node node_modules/puppeteer/install.js
yarn exec v1.19.1
Downloading Chromium r686378 - 110.2 Mb [====================] 99%

Always hangs at 99% here

I have to wait for this long, any workaroud please?

After a heavy debugging session turns out the end event never gets called. The end event of the response from the HTTPS request to download that zip file.

When I check on the file system, the zip file is there and can be uncompressed manually. Just the pipe hangs when running the installation.

if i install prject dependencies it via yarn install it stuck also at puppeteer

and i see no processbar
who i can enable it to see at least the processbar with a yarn install (i not use yarn add ...)

[rally25rs]

The "Downloading Chromium" step is part of Puppeteer's custom install script. This is not under yarn's control. Yarn just spawns their install script as a child process, then waits for that process to exit.

Please track this issue on Puppeteer's issues page.

if puppeteer would log something, then it would be visible via yarn install?

the problem here i is that there is no progressbar visible

Was having same problem, but clearing yarn cache worked for me.
yarn cache clean && yarn install
