Download fails when behind SSL inspection corporate proxy

Installation fails due to UNABLE_TO_GET_ISSUER_CERT_LOCALLY. I am behind a corporate proxy that does SSL inspection (with our own certificate authority), so I am not unused to this type of error. However, I have configured npm correctly:

PS C:\Users\ltheisen\git\facility-report-viewer-ui> npm config get cafile
C:\cygwin64\etc\pki\ca-trust\extracted\pem\tls-ca-bundle.pem

Along with the proper proxy settings:

PS C:\Users\ltheisen\git\facility-report-viewer-ui> gci env: | findstr proxy
http_proxy                     http://gatekeeper-w.mitre.org:80
https_proxy                    http://gatekeeper-w.mitre.org:80
no_proxy                       .mitre.org,.portal.local,localhost,mm206678-pc,mm206678-pc.mitre.org,127.0.0.1

And it works for normal installs. It seems like your install.js respects the https_proxy environment variable, but ignores the cafile setting. I’m not really surprised as it is an npm config and your code is built to work with npm/yarn/…, but I need a way to provide your installer with my CA file.

Steps to reproduce

Tell us about your environment:

• Puppeteer version: 0.13.0
• Platform / OS version: Windows 10 Enterprise
• URLs (if applicable):
• Node.js version: v9.3.0

What steps will reproduce the problem?

Please include code that reproduces the issue.

1. npm install --save-dev puppeteer

What is the expected result? Puppeteer gets installed.

What happens instead?

PS C:\Users\ltheisen\git\facility-report-viewer-ui> npm install puppeteer --save-dev

> puppeteer@0.13.0 install C:\Users\ltheisen\git\facility-report-viewer-ui\node_modules\puppeteer
> node install.js

@lucastheisen the tip-of-tree puppeteer is published to npm as puppeteer@next. Could you please give it a try?

npm install --save puppeteer@next

[lucastheisen]

@aslushnikov , it works:

PS C:\Temp\puppeteer> npm install --save puppeteer@next

> puppeteer@1.0.0-next.1515463970965 install C:\Temp\puppeteer\node_modules\puppeteer
> node install.js
