在PowerShell中安装Chocolatey的错误消息

Question

我正在尝试安装Chocolatey以与PowerShell一起使用.

建议的安装方法是复制并粘贴以下行.

@powershell -NoProfile -ExecutionPolicy unrestricted -Command "iex ((new-object net.webclient).DownloadString('http://chocolatey.org/install.ps1'))" && SET PATH=%PATH%;%systemdrive%\chocolatey\bin

但是我收到以下错误:

At line:1 char:13
+ @powershell -NoProfile -ExecutionPolicy unrestricted -Command "iex ((new-object  ...
+             ~~~~~~~~~~
Unexpected token '-NoProfile' in expression or statement.

+                    ~~
The token '&&' is not a valid statement separator in this version.

The splatting operator '@' cannot be used to reference variables in an expression. '@powershell' can be used only as
an argument to a command. To reference variables in an expression use '$powershell'.
    + CategoryInfo          : ParserError: (:) [], ParentContainsErrorRecordException
    + FullyQualifiedErrorId : UnexpectedToken

ExecutionPolicy设置为RemoteSigned,我正在运行Powershell v3

我尝试了一些应用安装代码而不是整行,但基本上,在@Powershell之后的任何东西都是意外的令牌.

Answer 1

您必须从cmd.exe("标准"命令提示符)开始该行,而不是从PowerShell开始.

Answer 2

在 PowerShell v3+ 中，最简单的方法是：

1. 打开 PowerShell 窗口（以管理员身份运行）

2. 检查PowerShell的版本是否大于3：

    $PSVersionTable.PSVersion
   

3. 启用 PowerShell 脚本的执行？

   set-executionpolicy remotesigned
   

4. 在 PowerShell 中

   iwr https://chocolatey.org/install.ps1 -UseBasicParsing | iex
