我目前正在 Docker 中使用 Next.js 和 Nginx 开发应用程序。
CSS 在我 build 一个项目并检查浏览器中的显示后，如下所示。
我该如何解决这个问题？
要部署的流程和代码如下:
1.制作下一个项目
$ npx create-next-app@latest --use-npm next-nginx-docker
2.制作一个Dockerfile.prod
FROM node:16-alpine AS builder
WORKDIR /app
COPY package.json ./
COPY package-lock.json ./
RUN npm install
COPY . .
RUN npm run build
FROM nginx:1.19-alpine AS server
COPY ./etc/nginx.conf /etc/nginx/conf.d/default.conf
COPY --from=builder /app /
EXPOSE 80
3.制作一个docker-compose.prod.yml
version: "3"
services:
app:
build:
context: .
dockerfile: Dockerfile.prod
ports:
- "80:80"
4.制作一个nginx.conf
server {
listen 80;
listen [::]:80;
server_name mydomain.com;
root /.next/server/pages;
index index.html;
}
5.将创建好的工程文件上传到远程服务器
6．在生产环境中启动容器
$ sudo docker-compose -f docker-compose.prod.yml up -d
7.当我在浏览器中查看显示时，CSS不起作用
8.查看浏览器显示的index.html的view-source
- 点击下方与 CSS 相关的链接会导致 404 错误。

9.查看容器中CSS文件的目录
/.next/static/css # pwd
[更新]
就像发布的答案一样，我更改了 Dockerfile 但 CSS 不起作用
FROM node:16-alpine AS builder
WORKDIR /app
COPY package.json ./
COPY package-lock.json ./
RUN npm install
COPY . .
RUN npm run build
FROM nginx:1.19-alpine AS server
COPY ./etc/nginx.conf /etc/nginx/conf.d/default.conf
COPY --from=builder /app /
COPY --from=builder /app/public /public
EXPOSE 80
Node 16.0
Next.js 12.1
最佳答案
在您的 HTML 文件中，静态文件路径以 _next 开头。但是您的 Next.js 生成的代码在从 .next 开始的路径中具有静态文件。
您必须更改您的 nginx 配置才能从正确的位置获取 CSS/静态文件。
server {
listen 80;
listen [::]:80;
location ~ ^/_next/static/(.*)$ {
root /.next;
try_files "/static/$1" "/server/static/o$1" @proxy_pass;
}
server_name mydomain.com;
root /.next/server/pages;
index index.html;
}
关于node.js - 为什么我在生产环境中 deproy Next.js 示例项目时 CSS 不起作用？，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/71739571/
