yarn run firefox fails in Fedora 24

[andreicristianpetcu]

yarn run firefox used to run a few weeks ago in Fedora 24 but now it fails.
Here is the stack trace

$yarn run firefox                                                                                                                                                 yarn run v0.17.10
$ node bin/firefox-driver --start 
/home/andrei/Dev/debugger.html/debugger.html/bin/firefox-driver.js:31
  let binary = new firefox.Binary();

It also fails with ndenv's nodejs.

Two small mentiones:

• I use Firefox Nightly;
• It works manually;

Strange, this looks like a gecko driver bug.

The create session is the tell for me

Perhaps file there as well

@tromey do you run fedora 24? Would you mind trying this?

[tromey]

First I got:

warning fsevents@1.0.15: The platform "linux" is incompatible with this module.
info "fsevents@1.0.15" is an optional dependency and failed compatibility check. Excluding it from installation.

Doesn't seem to be fatal.

Other than this it all worked for me. I had to uninstall the Fedora node and instead install the nodejs package from the nodesource repository.

[andreicristianpetcu]

@tromey It still does not work for me. I fetched the latest sources from debugger.html, I have nodejs package installed and not node. I also get the warning you are mentioning while running yarn install.

[jasonLaster]

@andreicristianpetcu I know this is a big ask, but mind re-installing node v7 from nodesource?

[jasonLaster]

closing this now as this is likely a node issue. Lets re-open it if something new comes in

[andreicristianpetcu]

I installed latest node with ndenv. I have v7.3.0 and it still failed. It's ok to close it.

[jasonLaster]

hmm, @andreicristianpetcu weird. mind trying this for node 7.x- https://github.com/nodesource/distributions#installation-instructions

Also, perhaps try getting node 7.0. maybe 7.3 is broken :/

[jasonLaster]

closing, but lets keep talking here if you find something.

[andreicristianpetcu]

To be honest, I have a good workaround and I do not have much interest in troubleshooting this. If it bugs other people then it might be important but for now it is not.
