在CentOS上安装PowerShell

微软刚刚开源了PowerShell，目前在Linux和MacOS上都能安装。具体的链接如下：

本文将介绍如何在CentOS 7.2下安装PowerShell。

首先在CentOS下下载PowerShell的安装包：

wget https://github.com/PowerShell/PowerShell/releases/download/v6.0.0-alpha.9/powershell-6.0.0_alpha.9-1.el7.centos.x86_64.rpm
或者：
wget https://hweast.blob.core.chinacloudapi.cn/soft/powershell-6.0.0_alpha.9-1.el7.centos.x86_64.rpm

 

安装时报错：

rpm -ivh powershell-6.0.0_alpha.9-1.el7.centos.x86_64.rpm
warning: powershell-6.0.0_alpha.9-1.el7.centos.x86_64.rpm: Header V3 RSA/SHA256 Signature, key ID be1229cf: NOKEY
error: Failed dependencies:
    libunwind is needed by powershell-6.0.0_alpha.9-1.x86_64
    libicu is needed by powershell-6.0.0_alpha.9-1.x86_64

需要通过yum安装两个依赖包：

yum install -y libunwind libicu

安装完成后，再次运行rpm安装成功。

rpm -ivh powershell-6.0.0_alpha.9-1.el7.centos.x86_64.rpm
warning: powershell-6.0.0_alpha.9-1.el7.centos.x86_64.rpm: Header V3 RSA/SHA256 Signature, key ID be1229cf: NOKEY
