Cuando construyo una imagen que debe compilarse a partir de mecanografiado, aparece este error.

sh: 1: tsc: no encontrado

El comando '/bin/sh -c npm run tsc' devolvió un código distinto de cero: 127

Aquí está el código relevante:

docker-compose.yaml

 version: '3.1' services: nodeserver: build: context: . target: prod ports: - "3000:3000" volumes: - ./src:/app/src - ./public:/app/public - ./templates:/app/templates

Este dockerfile funciona:

 FROM node:15.11.0 AS build WORKDIR /app COPY package.json . RUN npm install ADD . . RUN npm run tsc FROM node:15.11.0 WORKDIR /app COPY package.json . RUN npm install --production ADD public ./public ADD templates ./templates COPY --from=build /app/dist dist EXPOSE 3000 CMD npm start

Estoy usando este dockerfile como referencia, de un curso de Docker: https://github.com/BretFisher/docker-mastery-for-nodejs/blob/master/typescript/Dockerfile No veo lo que estoy haciendo mal , la etapa de origen debe tener las dependencias de desarrollo, entre ellas TypeScript, por lo que debería poder ejecutar tsc.

Cualquier ayuda apreciada. Gracias.

EDITAR:

Además de usar npm ci en lugar de npm install, tuve que copiar tsconfig.json en el directorio de trabajo (y copiar el directorio src en lugar de dist, que crea tsc) para que tsc funcione correctamente. Esta es la etapa de origen modificada en el Dockerfile:

 FROM dev AS source COPY src src COPY templates templates COPY public public COPY tsconfig.json tsconfig.json RUN npm run tsc
