Node.js应用程序在本地运行，但在docker上失败(sh:1:rimraf:未找到)

Question

我能够构建docker映像，但无法运行容器。这是包.json:

{
"name": "linked-versions-viewer",
"version": "1.0.0",
"description": "...",
"main": "./dist/bundle.js",
"type": "module",
"scripts": {
"test": "echo "Error: no test specified" && exit 1",
"clean": "rimraf dist",
"build_only": "rollup -c",
"build": "cross-env NODE_ENV=production npm run clean && npm run build_only",
"serve": "parcel src/index.html --port 12345",
"start": "npm run clean && npm run serve"
},
"repository": {
"type": "git",
"url": "..."
},
"author": "...",
"license": "...",
"dependencies": {
"antd": "^4.12.3",
"base-widget": "...",
"react": "^17.0.2",
"react-dom": "^17.0.1"
},
"devDependencies": {
"@types/node": "^14.14.28",
"@types/react": "^17.0.2",
"@types/react-dom": "^17.0.1",
"cross-env": "^7.0.3",
"parcel-bundler": "^1.12.4",
"rev-hash": "^3.0.0",
"rimraf": "^3.0.2",
"rollup": "^2.39.0",
"rollup-plugin-commonjs": "^10.1.0",
"rollup-plugin-node-resolve": "^5.2.0",
"rollup-plugin-replace": "^2.2.0",
"rollup-plugin-terser": "^7.0.2",
"rollup-plugin-typescript2": "^0.29.0",
"rollup-plugin-uglify": "^6.0.4",
"typescript": "^4.1.5"
}
}

这是码头文件：

FROM node:14.17.0 as base
ENV NODE_ENV=production
WORKDIR /app
COPY package*.json ./
RUN npm install
COPY . .
EXPOSE 8080
FROM base as production
ENV NODE_PATH=./build
CMD ["npm", "start"]

我通过运行docker build -t testapp .创建了映像，并尝试使用docker run -p 8080:8080 -d testapp运行容器，但它一直立即退出，代码为1。这是图像的错误日志：

> linked-versions-viewer@1.0.0 start /app
> npm run clean && npm run serve

> linked-versions-viewer@1.0.0 clean /app
> rimraf dist

我试着完全删除rimraf依赖项，但后来在包裹依赖项上出现了类似的错误，所以可能软件包安装不正确？如果有帮助的话，这个应用程序也是用字体编写的。

不知道下一步该做什么。谢谢你的建议。

表单npm install文档，

使用--production标志(或者当NODE_ENV环境变量设置为production时(，npm将不会安装devDependencies中列出的模块

由于base映像中有ENV NODE_ENV=production，因此rimraf和parcel-bundler都未安装在容器中。

您的npm start命令正在运行npm run clean && npm run serve。npm run clean使用rimraf模块，npm run serve使用parcel-bundler模块。这就是您看到这两个错误的原因。

您可以尝试以下解决方案之一，

1. 从Dockerfile中删除ENV NODE_ENV=production(这是最快的解决方案，但不应在生产中使用(

2. 您可以使用在容器内全局安装rimraf和parcel-bundler

   RUN npm install --global rimraf && npm install --global parcel-bundler
   

   然而，我仍然不认为这是一个好的生产准备设置。

3. 你可以在你的容器中使用npm run build正确地构建你的应用程序并提供它。然而，我对React的熟悉程度不够，无法帮助你在Docker上设置它。
