前幾天在用 sideproject，透過 vercel 部署，前幾次都成功，直到有次部署翻船了，出現錯誤訊息 Host key verification failed

Host key verification failed.

看到 Log 上面兩行，本以為是 ssh key 設定錯誤導致權限不足，做了幾個改變，像是邀請其他人到我的 github 專案協作，但問題依舊沒有解決！

耐心重看一遍 Log，找到了癥結點
Log訊息出現

1
Arguments: ls-remote --tags --heads ssh://gi[email protected]/ethereumjs/ethereumjs-abi.git

在我的案例中安裝了 ethers.js 套件，也有另外安裝依賴的套件 ethereumjs-abi
在安裝 ethereumjs-abi 發生問題！查了 Google 發現超多人有這個案例，只要透過 CICD 部署，不管是 Vercel、Gitlab 等等部署工具，只要用 npm install 跑過，部署就會出現以上的問題

解決方式

將 yarn.lock 或 package.lock 移除，並改用 yarn 安裝，不要使用 npm install

之所以會發生此問題，我另外一位協作者是 Windows 系統，電腦沒有安裝 Yarn，為了求快速是用 npm 來安裝套件，沒想到就這樣翻船了…
結論：同一專案協作者還是要說好，使用同一套的系統，yarn或npm

另一個解決方式是，開啟 yarn.lock 或 package.lock，找到 ethereumjs-abi，將 https:// 取代 git+ssh://
