when running docker-compose on the production server. Although I have successfully run it on a local machine, I really find it difficult to understand why this error occurred in the production server?
My package.json:
{
...
"dependencies": {
"@types/mocha": "2.2.41",
"@types/node": "7.0.22",
"@types/express": "^4.16.0",
...
"nodemon": "latest",
"puppeteer": "latest",
"reflect-metadata": "latest",
"typeorm": "0.2.16",
"typescript": "latest"
},
...
}
My Dockerfile:

Based on your dependency list my guess is that reflect-metadata is listed as a 'devDependencies' and not a regular dependency. Make sure it is listed in the correct section in package.json. Anything you need for running in production, you need in the dependencies section.
