原文提示如下：
Installing ASP.NET 5 On Mac OS X
By Steve Smith
ASP.NET 5 runs on the .NET Execution Environment (DNX), which is available on multiple platforms, including OS X. This article describes how to install DNX, and therefore ASP.NET 5, on OS X, using Homebrew.
In this article:
Install ASP.NET 5 on OS X
Install ASP.NET 5 on OS X
ASP.NET 5 requires DNX, which is installed and managed by the .NET Version Manager (DNVM). The DNVM is easily installed using a tool called Homebrew, which will also install the correct version of Mono for OS X.
Install Homebrew
The first step is to install Homebrew if it's not already installed. This can be done from a Terminal prompt using this script:
| ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)" |
The installer will inform you of the steps it is taking and pause before proceeding. You can learn more about Homebrew here.
到這一步，可能會出現 brew 已經安裝了。
可以執行:
| brew -v |
Install the .NET Version Manager (DNVM)
Once Homebrew is installed, install the DNVM by running brew tap aspnet/dnx from a Terminal window. If you need to update your version of DNVM, first run brew untap aspnet/dnx to delete the old commands, and then run the brew tap aspnet/dnx command again to get the updated scripts.
If you had an older version of our Homebrew "tap" configured, you might get the following error: Could not create link for aspnet/dnx/kvm, as it conflicts with aspnet/k/kvm. In that case, simply run brew uninstall kvm to ensure any old versions of kvm are removed, then brew untap aspnet/k to remove the old tap. After that, the brew tap aspnet/dnx command should succeed.
Next, run the command brew install dnvm to install the .NET Version Manager. This will also automatically install the latest DNX package from the https://www.nuget.org/api/v2 feed.
這一步可能出現沒有許可權的問題:
執行
| chown root:wheel /usr/local/bin/brew |
然後執行
| brew link mono |
完成安裝。 一切正常了。
Next, run dnvm to verify that your terminal understands this command. If it does not, run the command source dnvm.sh to link it, then try running dnvm again. You should see something like this:
使用Yemoman 建立Asp.net 專案
Mac 上 Asp.net 環境搭建好了以後，自己手動去開始一個 Asp.net 專案，是比較繁瑣的。 Yeoman 上已經有 Asp.net 的 generator.
如果沒有 Yeoman 先安裝 Yeoman， Yeoman 的介紹: http://yeoman.io/ Yeoman下面有各種專案基礎框架的generator
| > npm install -g yo |
安裝 Asp.net generator
| > npm install -g generator-aspnet |
使用 yeoman 開啟一個 Asp.Net 專案
| > yo aspnet |
這裡使用 Nancy 框架， Nancy的介紹: http://nancyfx.org/ 一個輕量級的 .Net Web Framework
選擇 Nancy ASP.Net Application
同時給一個專案名字，這裡用了 NacyApp
專案基礎檔案框架就生產了。
進入 NacyApp 目錄
執行
| dnu restore |
載入 依賴
如果 dnu 命令執行失敗， commond not found.
執行命令：
| source dnvm.sh |
如果執行 dnu restore 出現 http://nuget.org/api/v2/ 取依賴包找不到的問題，切換一下源再試試，有兩個可用的源:
1. https://www.myget.org/F/aspnetmaster/api/v2/
2. https://www.myget.org/F/aspnetvnext/api/v2/
例如:
| dnu restore -s "https://www.myget.org/F/aspnetmaster/api/v2" |
可以使用 core visual studio 開啟工程，開始寫程式。
然後 dnx . kestrel 開始你的 NacyApp 就可以了
這裡有個有意思的事情，在terminal 裡執行了 dnx . kestrel 後，如果想退出， 執行 ctrl＋c 了以後，看到 terminal 沒有反應，在瀏覽器裡重新整理一下頁面， terminal 會出一個錯誤， 就退出了。
