Question

我正在尝试在终端上运行：npm install -g firebase-tools以使用Firebase函数。

但是，当我这样做时，会得到以下错误输出：

npm WARN checkPermissions Missing write access to /usr/local/lib/node_modules
npm ERR! path /usr/local/lib/node_modules
npm ERR! code EACCES
npm ERR! errno -13
npm ERR! syscall access
npm ERR! Error: EACCES: permission denied, access '/usr/local/lib/node_modules'

npm ERR! A complete log of this run can be found in:
npm ERR!     /Users/myusername/.npm/_logs/2019-05-21T19_11_21_252Z-debug.log

我一直在经历这个。和他们推荐的事情要做，但我是。要么误解了说明，要么就不起作用。

我在做什么：

运行：curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.34.0/install.sh | bash
然后：command -v nvm有时不返回任何内容，而其他时间返回nvm，即使在这种情况下，运行Firebases行也会失败

我该如何解决？
