linux - 在 Linux 上运行 node.js 时如何解决 "Server terminated early with status 127"？

Question

我在这个版本的 Linux 上使用 Node 5.10.0

[davea@mydevbox mydir]$ uname -a
Linux mydevbox.mydomain.com 7.3.8-25.26.amzn1.x86_64 #1 SMP Wed Mar 16 17:15:34 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux

我在运行脚本时遇到以下错误(“服务器提前终止，状态为 127”)。我已经验证我可以使用“wget”访问相关的 URL，所以我不知道我还需要什么才能让这个东西正常工作……

[davea@mydevbox mydir]$ node myscript.js

/home/davea/node_modules/selenium-webdriver/lib/promise.js:654
    throw error;
    ^

就我而言，我缺少 Java 运行时环境 (JRE)。我在基于 Debian 的 docker 镜像中使用 Selenium 运行 e2e 测试，因此 apt-get install default-jre 为我解决了问题。遗憾的是 selenium 在这种情况下没有给出更有用的错误信息。
