问题描述
我在多人游戏中使用 Colyseus .该框架生成了一个打字稿服务器，我尝试将其部署到Heroku.我的日志中出现以下错误:
I am using Colyseus for my multiplayer game. The framework generated a typescript server which I tried to deploy to Heroku. I am getting the following error in my logs:

我的package.json:

这是tsconfig.json:

为什么Heroku找不到ts-node?
Why can't Heroku find ts-node?
推荐答案
ts-node在您的devDependencies中列出，但开箱即用时，它们不可用:
运行安装和构建步骤后在部署应用程序之前，Heroku将删除在devDependencies下声明的软件包.
After running the installation and build steps Heroku will strip out the packages declared under devDependencies before deploying the application.
如果您在运行时需要ts-node，建议将其移至dependencies.
If you need ts-node at runtime I suggest moving it to your dependencies.
其他解决方案是仅在构建时使用它(我不确定ts-node是否可行，但可能涉及将TypeScript编译为JavaScript)或配置Heroku不剥离您的devDependencies .我强烈建议不要使用最后一个选项-生产中不需要devDependencies.
Other solutions would be to use it only at build time (I'm not sure if this is possible with ts-node but it would probably involve compiling your TypeScript to JavaScript) or configuring Heroku not to strip your devDependencies. I strongly advise against this last option—devDependencies shouldn't be required in production.
