按照通过Powershell安装Chocolatey的步骤在我的Windows 7 64位PC上不起作用。我正在关注https://chocolatey.org/install#install-from-powershell-v3
我已确认ExecutionPolicy并且该系统路径已经确认 的powershell;

我在最后一行尝试了错误消息建议
Perhaps try setting $env:chocolateyUseWindowsCompression = 'true'
但这只会导致一系列其他错误

您正在下载UTF-8编码的文件（内容以特征UTF-8 byte order mark 开头），但它被视为ASCII文本。
此外：
我关注https://chocolatey.org/install#install-from-powershell-v3。
不，你不是。您引用的网站告诉您使用
iex ((New-Object System.Net.WebClient).DownloadString('https://chocolatey.org/install.ps1'))
按宣传方式工作，而您尝试使用
iwr https://chocolatey.org/install.ps1 -UseBasicParsing | iex
如果您想使用该方法，您需要先从内容中删除BOM，然后再将其汇总到Invoke-Expression：
(iwr https://chocolatey.org/install.ps1 -UseBasicParsing).Content -replace '^' | iex
