里面有一堆错误，我不知道为什么会这样。 但是经过多次研究，我尝试了很多方法，但我没有找到解决方案。所以任何帮助的家伙，我从 2 天以来就被困在这里

Answer 1

在指定节点版本的地方，还要指定节点版本。 看看它是否有效。它对我有用。

"engines": { "node": "12.x", "npm": "your version" }

Answer 2

指定对象块engines帮助我使用 Laravel 应用程序和 Rails 应用程序

package.json (append(

"engines": {
"node": "12.x"
}

有点奇怪，但是当它起作用时，它就会起作用。

我还添加了一个@dependabot变基，以便使用 heroku 的预览版本允许我在分支内验证这是阻止应用程序构建的唯一问题。

Answer 3

在终端中检查节点和 npm 的版本：

node -v
npm -v

并在您的 package.json 中更新两者(示例(：

"engines": {
"node": "14.x",
"npm": "7.x"
}

只是放置节点版本对我没有帮助，因为 Heroku 自动尝试构建另一个版本的 npm 并崩溃
