我一直在尝试安装最新的angular-cli以开始一个新项目，但我遇到了一个非常奇怪的问题。我跑的时候
npm install -g angular-cli@latest
angular-cli似乎安装成功。但是，当我实际尝试使用它或使用
检查版本时ng --version
我收到此错误：
fs.js:640
return binding.open(pathModule._makeLong(path), stringToFlags(flags), mode);

我找到了许多类似错误的答案，但他们似乎都暗示问题已在v1.0.0-beta.15中得到解决，而我应该已经安装了v1.0.0-beta.16。无论如何，当我按照最受欢迎的建议我可以找到评论ng（Version.assertPostWebpackVersion（）;）的第25行时，我只是得到了一个不同的错误：
→ ng --version

首先，确保您拥有Node 4.x和NPM 3.x。
请注意，Node 4.x（至少高达4.4.2，可能是更新的版本）附带NPM 2.x而非3.x。
因此，如果您有Node 4.x，请运行以下命令将NPM升级到最新版本：
npm i -g npm
（如果需要，请使用get Num from user
get IsPrime = True
for PFactor ranges from 2 to Num-1 do
begin block
if Num divisible by PFactor then set IsPrime = False
end block
if IsPrime = True then display Num is prime
else display Num is not prime
; BTW，如图所示运行install，而不是更新）
如果您有节点0.10或0.12，您可能想安装它，并在sudo目录中查找提及节点或npm的任何文件或文件夹并删除它们。那些版本太粘了。
现在，假设您拥有所有正确的版本，请运行：
npm rm -g angular-cli npm cache clear npm i -g angular-cli
如果这不起作用，请重复之前的3行，但将~/添加到安装行，这样就变为：
npm rm -g angular-cli npm cache clear npm i -g angular-cli --no-optional

尝试在没有 node_modules 和 package.json 的目录中运行ng --version，这会影响结果。
尝试执行以下操作以更新所有全局程序包：
npm update -g
