我正在尝试设置Firebase托管。
当我使用以下命令时：npm install -g firebase-tools
失败，该错误似乎是权限错误。我尝试遵循有关如何修复权限错误的指南，但无法使其正常工作。
您能带我逐步解决此问题吗？这将非常有帮助。
这是错误日志：

更新
我尝试再次手动更改npm的默认目录。
这可能已经解决了这个问题，如果解决了，我很想知道它是如何工作的，以及我在这里实际上做了什么：
Andrews-iMac:My Website andrewtillott$ mkdir ~/.npm-global
mkdir: /Users/andrewtillott/.npm-global: File exists
Andrews-iMac:My Website andrewtillott$ npm config set prefix '~/.npm-global'
Andrews-iMac:My Website andrewtillott$ export PATH=~/.npm-global/bin:$PATH
Andrews-iMac:My Website andrewtillott$ source ~/.profile
bash: /Users/andrewtillott/.profile: No such file or directory
