Heroku 节点/角度：部署应用程序和服务器

Question

我有一个简单的项目。 链接：https://github.com/Tyvain/BTCash

在本地我是这样启动的：

npm install
cd BTCash/server/
node app.js
cd BTCash/
npm start

我在 heroku 中尝试“github deployement”但得到了：

-----> Node.js app detected
-----> Creating runtime environment

   NPM_CONFIG_LOGLEVEL=error
   NPM_CONFIG_PRODUCTION=true
   NODE_ENV=production
   NODE_MODULES_CACHE=true
-----> Installing binaries
   engines.node (package.json):  unspecified
   engines.npm (package.json):   unspecified (use default)

   Resolving node version (latest stable) via semver.io...
   Downloading and installing node 6.9.1...
   Using default npm version: 3.10.8
-----> Restoring cache
   Skipping cache restore (new runtime signature)
-----> Building dependencies
   Installing node modules (package.json)

我应该如何在 heroku 上部署和启动它？我应该为此使用 travis CI 吗？

Answer 1

NPM 正在尝试运行 npm run typings install 安装后脚本，但 typings 包位于 devDependencies 部分中的 package.json。

由于 Heroku 上的 NODE_ENV 设置为“生产”，因此不会安装这些软件包，因此 npm postinstall 脚​​本将无法在 Heroku 上完成。

尝试将typings 移动到package.json 中的dependencies 部分。

另外，阅读Heroku NodeJS development documentation 了解更多有用的信息。例如，您确实应该在 package.json 中指定 NodeJS 和 NPM 版本。
