缺少一些依赖项导致了这个问题 (https://www.centos.org/forums/viewtopic.php?t=60908&start=10)

yum install liberation-mono-fonts liberation-narrow-fonts liberation-sans-fonts liberation-serif-fonts

安装以上软件包解决了问题!

希望对您有所帮助。

这个错误信息...

...意味着您的系统中没有 setuid 沙箱,因此该程序无法initiate/spawn 新的浏览上下文Chrome 浏览器 会话。


解决方案

正如您在配置 --no-sandbox--disable-setuid-sandbox 时看到的错误,根据 Linux SUID Sandbox Development 中的文档需要一个 SUID 辅助二进制文件来打开沙箱在 Linux。在大多数情况下,您可以使用以下命令为您安装合适的沙箱:

build/update-linux-sandbox.sh

此程序将在 /usr/local/sbin 中为您安装正确的 沙盒 并在需要时告诉您更新 .bashrc

但是,可能会有一些例外,例如,如果您的 setuid 二进制文件已过期,您将收到如下消息:

Running without the SUID sandbox! 

The setuid sandbox provides API version X, but you need Y
You are using a wrong version of the setuid binary!

在这些情况下,您需要:

  • 每当您构建 chrome 时构建 chrome_sandboxninja -C xxx chrome chrome_sandbox 而不是 ninja -C xxx chrome
  • 构建完成后,执行update-linux-sandbox.sh.

    # needed if you build on NFS!
    sudo cp out/Debug/chrome_sandbox /usr/local/sbin/chrome-devel-sandbox
    sudo chown root:root /usr/local/sbin/chrome-devel-sandbox
    sudo chmod 4755 /usr/local/sbin/chrome-devel-sandbox
    
  • 最后,您必须在 ~/.bashrc(或 .zshenv)中包含以下行:

    export CHROME_DEVEL_SANDBOX=/usr/local/sbin/chrome-devel-sandbox
