如何在ubuntu 16,04上安装angular-cli？

Question

我正面临在本地安装angular-cli的问题.我在Ubuntu 16.04.2 LTS上使用以下版本的node.js和npm:

node: v7.10.0 
npm: 3.10.10

我尝试使用以下命令安装angluar-cli:

$npm install -g @angular/cli@1.0.0

这工作正常,并完成以下警告:

npm WARN optional SKIPPING OPTIONAL DEPENDENCY: 
fsevents@^1.0.0 (node_modules/@angular/cli/node_modules/chokidar/node_modules/fsevents):
npm WARN notsup SKIPPING OPTIONAL DEPENDENCY: Unsupported platform
    for fsevents@1.1.1: wanted {"os":"darwin","arch":"any"} (current:
    {"os":"linux","arch":"x64"})

现在当我正在尝试'ng'命令时:

  module.js:472
   throw err;
   ^
   Error: Cannot find module 'abbrev'
   at Function.Module._resolveFilename (module.js:470:15)

只需在命令行执行此操作:

sudo npm uninstall -g @angular/cli
sudo npm cache verify
sudo npm install -g @angular/cli --unsafe-perm=true --allow-root

在这里找到:错误:EACCES:权限被拒绝,mkdir ......!

这修复了npm EACCES权限被拒绝哪个为我设置了ubuntu 17.04上的angular/cli安装.
