当构建需要从TypeScript编译的映像时，我会遇到此错误：
sh: 1: tsc: 找不到命令
命令'/bin/sh -c npm run tsc'返回非零代码：127
以下是相关代码：
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

这个 Dockerfile 是有效的：
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
我在参考这个Dockerfile，它来自于一门Docker课程：https://github.com/BretFisher/docker-mastery-for-nodejs/blob/master/typescript/Dockerfile 我不知道我做错了什么，源阶段应该具有开发依赖包，其中包括typescript，所以应该能够运行tsc。
非常感谢任何帮助。
编辑:
除了使用npm ci而不是npm install之外，我还需要将tsconfig.json复制到工作目录（同时复制src目录而不是由tsc创建的dist目录），才能使tsc正常工作。下面是修改后的Dockerfile中的源阶段：
FROM dev AS source
COPY src src
COPY templates templates
COPY public public
COPY tsconfig.json tsconfig.json
RUN npm run tsc
ENV NODE_ENV=production行移动到RUN npm ci和RUN npm run build之间后，解决了我的问题。 - Oren ChapoRUN npm prune --production。 - dcsan
