如何在 M1 Macbook 順利執行 Azure Functions (無需 Rosetta)
2022-02-09
Azure Functions 其中一個令我最愛的功能，就是有十分完整的工具配套，讓我很方便就可以在本地進行不同的測試，模擬到實際 Azure Functions 的環境，而不需要費時不斷 deploy 上雲端。
最近購入了 M1 Macbook，心血來潮嘗試重啟一些 Azure Functions 的專案，怎料畫面都一遍紅，即使在全新的專案也遇到同樣情況！

即使最後仍能看到 endpoint 的 URL，但是 function 都是不會執行起來，最後還會有 timeout 的情況出現。而從以上的錯誤信息可以看到，其中一個重點就是 M1 的 arm64 結構導致問題發生：

似乎就是相關的工具還沒有支援到 arm64， 但 M1 都推出了一年多了，相信微軟不會放棄我們這批用戶那麼久吧？幸好最後解決方法是出現在一個微細處！
我所安裝的工具
若然你是第一次接觸 Azure Functions，或者遇到同樣問題來到這裡，也先確認一下我們的環境是同樣的！我剛剛測試的時候，使用了以下的工具：
- Macbook Pro M1
- Visual Studio Code
- Extension: Azure functions
- Node.js 14 LTS (arm64)
- 透過 npm 安裝了 azure-functions-core-tools
嗯，在上一段落，就是最後一行我透過 npm 安裝了 azure-functions-core-tools，因為我自己較喜歡把各個專案的 dependencies 都分開（就算使用 python 也特別鍾情 venv），所以順利成章就使用 npm 來執行 func 這個屬於 azure-functions-core-tools 用來本地測試的指令。
問題所在
本身也覺得什麼不妥當，忽然想到可能是 node.js 版本的問題，於是我便升級至 node.js 16，問題就出現了！竟然說不支援 node.js 16，細心一看，原來我執行的 Azure Function Runtime 仍然停留在 3.3.1.0

查看一次 azure-functions-core-tools 的 github 專頁 ，終於水落石出，原來自從版本 4 之後，安裝的方法不同了！
當我使用了 homebrew 的方法安裝到最新版本的 azure-functions-core-tools 後，問題就迎刃而解，所有 Functions 都順順利執行囉！
解決方法: 使用 brew 安裝最新的 azure-functions-core-tools 工具
換句話說，暫時只有 version 4 的 azure-functions-core-tools 能支援 M1 Macbook， 不論是 node.js 14 或 16 都能夠使用。
而且切記不要使用 npm 來安裝 azure-functions-core-tools，即使之前的專案使用了這個方法，都謹記要先移除舊版本的 tools！
