我正在尝试按照本指南安装量角器：
https://angular.github.io/protractor/#/
在 ubuntu 的 shell 上，我输入了：sudo npm install -g protractor
有一大堆信息告诉某些特定软件包的安装是否顺利。在这里，我在某些软件包上遇到一些错误。我添加了错误，但没有添加进展顺利的错误。任何人都知道如何解决此问题。
感谢您提供的任何帮助

在 Ubuntu 上，Node 命令实际上是 'nodejs'，而量角器安装程序正在寻找 'node'。
尝试运行以下命令：
sudo ln -s /usr/bin/nodejs /usr/bin/node
然后重新运行量角器安装
sudo npm install -g protractor
