將應用推送到 Heroku 時出現錯誤代碼 ELIFECYCLE

Question

我正在嘗試將我的 angular 項目應用程序推送到 Heroku 但這樣做會收到錯誤。 我已經看到有關刪除 node_modules 和安裝 npm 的線程，但是，這對我不起作用。

這是構建日志的樣子：

我能做些什么來解決這個錯誤？

將“node”：“12.20.x”添加到“engines”后：

Answer 1

看起來錯誤出在package.json中的 Angular 構建腳本中，而不是 Z1A794174361C9ADBE88EFAD9B 本身。

Angular CLI 在錯誤中顯示它至少需要 Node.js v12.20 ，但您當前使用的是v12.18.2 。

要強制 Heroku 使用特定版本的 Node，您可以在package.json中的engines object 中指定版本

只需將其添加到您的package.json並將應用程序重新部署到 Heroku。

"engines": {
    "node": "12.20.x"
}

我建議在部署新項目時使用最新的 LTS 版本，以盡可能長時間地保持最新狀態。

可以在此處找到有關使用自定義構建參數將 Node 應用程序部署到 Heroku 的其他文檔。
