electron error: symbol lookup error, undefined symbol about nightmare-heroku

[causztic]

@ubuntugod did you try my buildpack instead as it has an updated electron version? https://github.com/causztic/heroku-electron-buildpack

I was able to run electron with nightmare with the updated version.

I am able to get it working on heroku by updating the electron-install-buildpack's electron version to be the same as Nightmare.js's. I have made a pull request on their repo
benschwarz/heroku-electron-buildpack#2

You can also give my fork a try and see whether it works for you.

@oscarmorrison This is what I get after deploying https://github.com/oscarmorrison/nightmare-heroku:

• nightmare queueing action "goto" for http://blog.oscarmorrison.com/nightmarejs-on-heroku-the-ultimate-scraping-setup/ +11ms
• nightmare queueing action "wait" +1ms
• nightmare queueing action "evaluate" +0ms
• nightmare running +2ms
• electron:stderr /app/node_modules/electron/dist/electron: symbol lookup error: /app/node_modules/electron/dist/electron: undefined symbol: _ZN12v8_inspector8protocol8Debugger3API6Paused10ReasonEnum3XHRE +161ms
• nightmare electron child process exited with code 127: command not found - you may not have electron installed correctly +11ms
• nightmare electron child process not started yet, skipping kill.

This is displayed when I execute the code as heroku run DEBUG=nightmare*,electron:* node --harmony index.js.

Someone please help.

@causztic Yes, I forked from your commit to https://github.com/ubuntugod/heroku-electron-buildpack.

I am new to heroku(been playing with it for about 1 day). I added the above buildpack to the .buildpacks file such that its content is:

• https://github.com/heroku/heroku-buildpack-apt
• https://github.com/captain401/heroku-buildpack-xvfb.git
• https://github.com/ubuntugod/heroku-electron-buildpack.git
• https://github.com/heroku/heroku-buildpack-nodejs.git

Then I deployed it to heroku. During the depolyment I could see these in the console:

• remote: -----> Electron app detected
• remote: -----> Extracting Electron 1.8.4 binaries to /tmp/build_ef2080b7a4a37719b8d0869bd9ba943e/vendor/electron

I assume this makes sure that the latest version of electron will be available later.

But there was something that didn't feel right to me. I had that feeling when I saw these lines in the console before the above lines:

• remote: -----> Xvfb-setup app detected
• remote: -----> Electron app detected
• remote: -----> Extracting Electron 0.37.6 binaries to /tmp/build_ef2080b7a4a37719b8d0869bd9ba943e/vendor/electron
• remote: -----> Moving Electron to /tmp/build_ef2080b7a4a37719b8d0869bd9ba943e/vendor/electron

I am not sure why the 0.37.6 binaries are being extracted even when I applied the latest buildpack for electron from your repo.

I still get this error:
electron:stderr /app/node_modules/electron/dist/electron: symbol lookup error: /app/node_modules/electron/dist/electron: undefined symbol: _ZN12v8_inspector8protocol8Debugger3API6Paused10ReasonEnum3XHRE +161ms
I am not sure what I am doing wrong. I am using the Cedar-14 stack on heroku.

UPDATE
I just checked the buildpacks currently applied to heroku by running heroku buildpacks and I saw that the BUILPACK URL that had the old electron version was also there. So, I removed it. Then, deployed the app again and now it works like a charm.

Thanks @causztic for the electron buildpack.

[causztic]

glad it worked out for you!

[seanpascoe]

thanks @causztic, your buildpack works great!

[damaneice]

Has anyone gotten this to work using the Heroku-16 stack?
