Node/React 应用程序不会部署到 Heroku

【问题描述】：

我的应用有一个 React 前端和一个 Node 后端； BE 通过 API 提供 FE 数据。它不会部署到 Heroku——堆栈跟踪如下。

我尝试过的事情：

This question。我已经尝试在答案中提到的模型存储库之后对我的 package.json 文件进行建模，但没有运气。 部署上述模型存储库，效果很好。 将模型存储库部署到我自己失败的 heroku 应用程序中 - 它运行良好，因此 Heroku 不是问题。 This question（我已经检查过 react-scripts 被列为依赖项而不是开发依赖项）。

我可能最终会以模型存储库为起点，并逐步复制我的项目，但如果您能提供任何有关可能出现问题的信息，我将不胜感激。

【问题讨论】：

你最终找到解决方案了吗？

嗨@ViceSallés，如果我没记错的话，同事的节点配置损坏了 package-lock.json 文件。正如我在问题中提到的那样，我们最终将代码复制到模型存储库中。

【参考方案1】：

您好，您的后期构建脚本需要修改，请遵循此约定

将 reactFolderName 替换为包含 react 前端的文件夹名称 将下面的 sn-p 添加到脚本下的 package.json 中

    scripts
    "heroku-postbuild": "NPM_CONFIG_PRODUCTION=false npm install --prefix reactFolderName && npm run build --prefix reactFolderName"

并将这个 sn-p 添加到您的 index.js 文件中

    app = express()
    app.use(express.static('reactFolderName/build'));
    app.get('*', (req, res) => res.sendFile(path.resolve(__dirname, 'reactFolderName', 'build', 'index.html')));
