我正在尝试通过Heroku部署我的应用程序，这完全适用于localhost。即使我在localhost上安装java模块时遇到了一些麻烦，但由于这篇文章：https://github.com/nodejs/node/issues/10289，我终于做到了。
现在，我在Heroku上部署应用程序时显然遇到了同样的错误，但现在我无法修复它。我甚至设置了Java Buildpack，以防万一，但它没有帮助。
我希望有人可以帮助我！
这是我的package.json：

答案 0 :(得分：3)
您的node-gyp似乎需要正确构建java。 Heroku的架构是它只为您提供您指定/需要的东西。现在我不认为Heroku知道它需要一个JVM来运行你的应用程序。所以你应该提供一个buildpack。非常简单的构建包是一组规则告诉Heroku如何设置，安装和构建。有一个名为heroku/jvm的JVM构建包。
因此，您需要做的是通过仪表板或CLI通过heroku buildpacks:add heroku/jvm将其添加到您的应用程序中。
还有一件事要做。由于您的应用程序本身需要javac，我们应该提取java / jvm的构建顺序。所以在这种情况下你应该做heroku buildpacks:add --index 1 heroku/jvm。这将JVM buildpack置于位置1并按顺序推送所有其他buildpack。
现在，当应用程序开始构建时，它首先设置JVM（从而为您的实例启用javac），然后运行NodeJS构建。此构建现在将从当前实例中获取javac并进行相应的构建。
