Node.js 使用docker compose卷时,不会基于本地更改更新docker容器文件

Node.js 使用docker compose卷时,不会基于本地更改更新docker容器文件,node.js,docker,docker-compose,volumes,Node.js,Docker,Docker Compose,Volumes,当我对本地文件(express server.js)进行更改时,我在docker compose终端中没有看到更改通知。这意味着docker容器文件没有更新。(终端输出底部打印的“检查”字符串来自console.log('check')调用,但如果我在本地更改此字符串参数,然后保存,则在终端中看不到新的字符串输出。)。 (这是使用docker工具箱和oracle虚拟工具箱的windows 7) Dockerfile: FROM node:10.16.3 WORKDIR /usr/src/ C

什么是主机操作系统?为什么不在主机上运行
nodemon
;为什么需要将其包装在Docker容器中?@DavidMaze这是使用Docker工具箱和oracle虚拟工具箱的windows 7。我对nodemon不太清楚……我是新手,所以从教程中了解了nodemon的设置。
