巧克力不会安装

Question

通过Powershell安装Chocolatey的步骤并不适用于我的Windows 7 64位个人电脑。我下面https://chocolatey.org/install#install-from-powershell-v3

• 我已经证实了ExecutionPolicy和系统路径具有 PowerShell的;

  PS C:\Users\a> Get-ExecutionPolicy

• 我试图在最后一行

  Perhaps try setting $env:chocolateyUseWindowsCompression = 'true' 
  

  但是，这不仅导致了一系列其他错误

PS C:\admin\scripts>iwr https://chocolatey.org/install.ps1 -UseBasicParsing

你的错误消息的建议下载一个UTF-8编码的文件（内容以UTF-8的特征开始byte order mark ），但它被视为ASCII文本。

除了：

我下面https://chocolatey.org/install#install-from-powershell-v3。

不，你不是。你引用的网站告诉你使用

iex ((New-Object System.Net.WebClient).DownloadString('https://chocolatey.org/install.ps1')) 

，而你正在尝试使用

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

如果你想用这种方法，你需要从内容中删除BOM这像宣传的那样，管道入Invoke-Expression前：

(iwr https://chocolatey.org/install.ps1 -UseBasicParsing).Content -replace '^' | iex
