Running CasperJS with SlimerJS in CentOS and Ubuntu Server. Server Environment.

[corderogerardo]

versions

• SlimerJS: 0.10.2
• Firefox: 50.0
• Operating system: Ubuntu 16.04 64Bits and CentOS 7 Server.

Steps to reproduce the issue

I have two serversThe initial setup in the server is with no graphical user interface which is normal in Servers for production. Then I follow the steps in the SlimerJS official documentation about installing Firefox, using export to set slimer to firefox. Installing xvfb to run casperjs with slimerjs in headless mode. The command: xvfb-run casperjs caspercaptchaweb.js --engine=slimerjs --debug=true

Actual results:

libGL error: No matching fbConfigs or visuals found libGL error: failed to load driver: swrast 2016-11-30T13:13:20.675Z [DEBUG] Gecko version: 50.0 2016-11-30T13:13:20.675Z [DEBUG] script args: /usr/lib/node_modules/casperjs/bin/bootstrap.js --casper-path=/usr/lib/node_modules/casperjs --cli caspercaptchaweb.js 2016-11-30T13:13:20.676Z [DEBUG] Configuration: debug=true 2016-11-30T13:13:20.676Z [DEBUG] Configuration: Script=/usr/lib/node_modules/casperjs/bin/bootstrap.js 2016-11-30T13:13:20.676Z [DEBUG] Configuration: workingDirectory=/home/devtobmaps JavaScript strict warning: coffee-scripts.js, line 8: SyntaxError: test for equality (==) mistyped as assignment (=)?

Finish the captcha? .

My CasperJS script solves a captcha downloading the image, using another NodeJS Script that solves the captcha image, save it in a file with FS and from CasperJS and FS search for the solution and solve the captcha.

But the error happens with one of my simpler CasperJS script.

I really need to solve this problem. Thank you very much for your help.

Hi,

the real issue is here:

libGL error: No matching fbConfigs or visuals found
libGL error: failed to load driver: swrast

If you do a search about these errors, you'll find it is about your operating system and your graphic card drivers and/or graphical environment. I think that if you launch only firefox + xvfb, you'll have the same problem. Probably some packages about Xorg, Nvidia or else are missing.

So I don't think it is related directly with Slimerjs.

Please confirm or unconfirm that assumption.

Hi @laurentj , Thank you. I think you were right I am reproducing the error and confirming! Thank you. I search more about the graphic card and drivers, and test.

I create a Digital Ocean Droplet with Ubuntu 16.04. The drivers are virtual, from Red Hat. 00:02.0 VGA compatible controller: Red Hat, Inc. QXL paravirtual graphic card (rev 04)

And

I think my solution was to install nvidia drivers following the steps here : http://stackoverflow.com/questions/19856192/run-opengl-on-aws-gpu-instances-with-centos

Now I having this error, but that doesn't stop the execution of the script.

I am going to confirm creating another Droplet in Digital Ocean and test to help more people to be able to work CasperJS with --engine=slimerjs and Xvfb.
