I am trying to running Casperjs with Slimerjs

  • I Installed SlimerJS 0.10.2
  • I have installed Mozilla Firefox 45.5.1 (tried with 50 too)
  • I have installed CasperJS 1.1.3
  • I have installed xvfb 1.17.4

Running on Centos 6.8

When tried to run a casperjs+slimerjs from php I get:

Gecko error: it seems /usr/bin/firefox is not compatible with SlimerJS.
See Gecko version compatibility. If version is correct, launch slimerjs
with --debug=true to see Firefox error message

When I try to run a script from console with debug=true like: /usr/local/bin/casperjs /tmp/casperjs-5cn484 --debug=true --engine=slimerjs (I tried with xvfb-run too)

I get this error:

Xlib:  extension "RANDR" missing on display ":99".
process 5588: D-Bus library appears to be incorrectly set up; failed to read machine uuid: Failed to open "/var/lib/dbus/machine-id": No such file or directory
See the manual page for dbus-uuidgen to correct this issue.
  D-Bus not built with -rdynamic so unable to print a backtrace
Redirecting call to abort() to mozalloc_abort

/usr/lib/node_modules/slimerjs/src/slimerjs: line 167:  5588 Segmentation fault      "$SLIMERJSLAUNCHER" -app "$SLIMERDIR/application.ini" $PROFILE -no-remote "$@"

if i run slimerjs --debug=true, I get:

Error: cannot open display: :1.1 Gecko error: it seems /usr/bin/firefox is not compatible with SlimerJS. See Gecko version compatibility. If version is correct, launch slimerjs with --debug=true to see Firefox error message

I already tried a lot of solution, like:

  • tried: Xvfb :1 -screen 0 1024x768x24 +extension RANDR & and export DISPLAY=:1 (with :99 too)
  • tried export LD_LIBRARY_PATH=/usr/lib/x86_64-linux-gnu/
  • upgrade downgrade firefox version
  • check if there was fonts, there is one, so no problem

I don't know what I am trying anymore, some suggestions? : )

Anyway I get it running installing dbus package and with the comand:

dbus-uuidgen > /var/lib/dbus/machine-id

The Xlib: extension "RANDR" missing on display ":99" isn't a big issue...

Did you see this issue? Apparently you should:

Change the max version in src/application.ini MaxVersion=45.*

I'm not sure about the xrandr error but it seems unrelated. Could be a result of experimentation or a red herring.

There's also a DBUS error that could be causing the subsequent segmentation fault.

I suggest you try to check it step by step:

  • see that firefox is working
    • X forwarding might help here, it would bring up the remote firefox window locally
  • make sure that firefox is working headless
  • check with slimerjs
  • check with your PHP wrapper script

  • I have already checked the version issue, is it very old, now the default value is already 50.* – Apoleo Dec 22 '16 at 19:45
