节点版本不兼容的移动文件"/>
部署到Heroku失败。与节点版本不兼容的移动文件
我正在努力将新的Rails 6应用程序部署到heroku。它在我的本地计算机上运行良好。在部署过程中,我收到以下输出。
[不幸的是,我是webpack和yarn的新手。似乎是移动文件的版本/依赖性问题,而这又似乎是webpacker的依赖性。但是,我不知道该如何解决。
似乎可以归结为这一行:
error [email protected]: The engine "node" is incompatible with this module. Expected version ">=10.17". Got "10.15.3"
但是,节点不是我的节点模块之一,但似乎是已安装的二进制文件。当我运行
node - v
我得到:v12.16.1
任何帮助将不胜感激。

如果您需要其他日志或代码示例,请告诉我。我很茫然。
=====================更新:
我在heroku上找到了有关buildpacks和node的文档:-
基于此,我将我的package.json文件更改为如下所示:
},
"version": "0.1.0",
"engines": {
"node": "12.16.x"
},
"devDependencies": {
"webpack-dev-server": "^3.10.3"
}
现在,错误消息已更改为:
remote: Running: rake assets:precompile
remote: yarn install v1.16.0
remote: [1/5] Validating package.json...
remote: error [email protected]: The engine "node" is incompatible with this module. Expected version "12.16.x". Got "10.15.3"
remote: error Found incompatible module.

我假设package.json文件中的更新将导致heroku使用指定的节点版本。但是,事实并非如此。
回答如下:问题是:如何定义heroku使用哪个节点版本?
需要一些研究来解决这个问题。Heroku可以为每个应用程序应用多个构建包。在这种情况下,顺序很重要。我指定先运行nodejs buidlpack,然后再运行ruby buildpack。只有这样,package.json中的“ engine”定义才会生效。如果使用ruby buildpack,则节点版本默认为10.15.3。但是,如果首先执行nodejs buildpack,它将安装package.json文件中指定的版本。https://devcenter.heroku/articles/ruby-support#installed-binaries
