尝试从npm安装Angular 2材质-源文本中无法识别的令牌 [英] Trying to install Angular 2 Material from npm - unrecognized token in source text

问题描述

我尝试从PowerShell(以管理员身份)使用以下命令

I try the following command from PowerShell (as Administrator)

npm install @angular2-material

并得到错误:

Unrecognized token in source text.
At line:1 char:13
+ npm install  <<<< @angular2-material
    + CategoryInfo          : ParserError: (:) [], ParentContainsErrorRecordException
    + FullyQualifiedErrorId : UnrecognizedToken

我什至尝试只获取一个A2M组件(核心)，并得到相同的错误:

I've even tried getting just a single A2M component (core) and get the same error:

npm install @angular2-material/{core}

知道我在做什么错吗?
npm:3.9.5
节点:6.2.2
操作系统:Win7

Any idea what I'm doing wrong?
npm: 3.9.5
node: 6.2.2
OS: Win7

更新:
我在A2M GitHub上发现了以下问题-似乎可能是PS的问题.

Update:
I found the following issue on A2M GitHub - seems like it might be an issue with PS.

更新2:
使用cmd代替PS可以工作.

Update 2:
Using cmd instead of PS works.

推荐答案

@使PowerShell将@ angular2-material视为变量.

The @ is making PowerShell treat @angular2-material as a variable.

• 您可以使用cmd.exe(命令外壳)代替PowerShell

或

• 您可以在包装中用引号引起来:例如"@angular2-material"
