我該如何解決呢？可能是什麼問題？

Answer 1

我認爲問題始於節點安裝。 使用

node -v 
npm -v 

節點必須是最新版本，請檢查節點版本爲v8.5.0和NPM必須是最新版本5.4.1

那麼請使用

npm install -g @angular/cli 

然後重新安裝角CLI檢查版本

ng -v 

版本將是1.4.1，如果一切正常，你可以創建

ng new myNewProject 

Answer 2

你應該在訂單直接調用納克命令全局安裝角客戶機的項目，請運行：

npm install -g @angular/cli 

Answer 3

更新或安裝角度CLI包用下面的命令：

c:\ npm install -g @angular/cli 

後，通過以下命令在所需的位置創建一個新項目：

c:\ npm new projectName
