win10安装Chocolatey报"请求被终止，未能创建SSL/TLS安全通道"

以管理员身份运行

@powershell -NoProfile -ExecutionPolicy Bypass -Command "iex ((New-Object System.Net.WebClient).DownloadString('https://chocolatey.org/instal...'))" && SET "PATH=%PATH%;%ALLUSERSPROFILE%chocolateybin

 

报如下错误

另外一台电脑运行同样的指令不报错，也能打开https://chocolatey.org/install.ps1

参考官方给出的troubleshooting ，应该是TLS版本的问题

在Power shell运行下面3条指令

1.

[Enum]::GetNames([Net.SecurityProtocolType]) -contains 'Tls12'

2.If the result is True then your system supports TLS 1.2. You can find out which protocols are being used by running:

[System.Net.ServicePointManager]::SecurityProtocol.HasFlag([Net.SecurityProtocolType]::Tls12)

3.If the result is True then TLS 1.2 is being used . However, you can add TLS 1.2 explicitly by using:

[Net.ServicePointManager]::SecurityProtocol = [Net.ServicePointManager]::SecurityProtocol -bor [Net.SecurityProtocolType]::Tls12

我的情况是步骤2返回false，执行第3条后再运行Chocolatey安装指令问题解决~
