我正在嘗試用 Docker 包裝我的節點快速后端。但是，在運行我的 docker-compose 檔案時。我npm install在整個 dockerfile 中運行stage時遇到錯誤，說它沒有找到在我的本地目錄中復制到我的容器內的目錄中的 package.json。下面是我的專案目錄結構。嘗試使用 nginx 代理我的節點快速后端 API。任何可以幫助我努力實作的資源都非常感謝。
錯誤日志：
> [4/5] RUN npm install:
#8 0.697 npm ERR! code ENOENT

uj5u.com熱心網友回復：
你已經設定了背景關系：
context: ./docker
所以當你跑
COPY . ./
您正在從該背景關系中復制檔案，其中不包括package.json. 您可以指定 Dockerfile：
express:
container_name: express_container
build:
dockerfile: ./docker/Dockerfile
environment:
ports:
- "5000:5000"
但我建議重組檔案夾以在有意義的地方將每個影像分開。
