CasperJS与Slimerjs - Xlib:扩展"RANDR"缺少显示":99"

Question

我正在尝试用Slimerjs运行Casperjs

• 我安装了SlimerJS 0.10.2
• 我安装了Mozilla Firefox 45.5.1(也尝试过50)
• 我已经安装了CasperJS 1.1.3
• 我已经安装了xvfb 1.17.4

在Centos 6.8上运行

当试图从php运行casperjs + slimerjs我得到:

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

当我尝试使用debug = true从控制台运行脚本时:( /usr/local/bin/casperjs /tmp/casperjs-5cn484 --debug=true --engine=slimerjs 我也试过xvfb-run)

我收到此错误:

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" $PROFILE -no-remote "$@"

如果我跑slimerjs --debug=true,我得到:

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

我已经尝试了很多解决方案,例如:

• 试过:Xvfb :1 -screen 0 1024x768x24 +extension RANDR &和export DISPLAY=:1(同时:99)
• 试着 export LD_LIBRARY_PATH=/usr/lib/x86_64-linux-gnu/
• 升级降级firefox版本
• 检查是否有字体,有一个,所以没问题

我不知道我在尝试什么,一些建议？:)

无论如何，我让它运行安装 dbus 包并使用命令：

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

这Xlib: extension "RANDR" missing on display ":99"不是一个大问题...
