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 Preparing... ################################# [100%] Updating / installing... 1:powershell-6.0.0_alpha.9-1 ################################# [100%]
成功后，可以运行powershell启动powershell环境：
