将反应应用程序作为 docker 容器运行时找不到反应脚本答案

【问题标题】：Cannot find react-scripts when running react app as a docker container将反应应用程序作为 docker 容器运行时找不到反应脚本
【发布时间】：2022-01-13 12:21:31
【问题描述】：

我有一个我正在尝试 dockerize 的 react 应用程序。以下是我的 Dockerfile 的内容

FROM node:alpine
WORKDIR /src
COPY package.json /src
RUN npm install
COPY . /src
EXPOSE 3000
CMD ["npm", "run", "start"]

在构建 docker 文件时出现以下错误。

 > [5/6] RUN npm install:
#9 13.99 npm ERR! code ERESOLVE

#9 14.00 npm ERR!     /root/.npm/_logs/2021-12-08T14_34_26_174Z-debug-0.log

然后我将运行命令更改为使用RUN npm i -g npm，如下所示。

FROM node:alpine
WORKDIR /src
COPY package.json /src
RUN npm i -g npm
COPY . /src
EXPOSE 3000
CMD ["npm", "run", "start"]

这似乎构建了没有错误的图像，但是当我尝试将 docker 图像作为容器运行时，容器退出并且在获取日志时我看到以下错误

> <projectname>-ui@1.1.6 start
> react-scripts start

sh: react-scripts: not found

更新

当我使用RUN npm i --legacy-peer-deps 时出现以下错误

我做错了什么？

【问题讨论】：

你可能还应该把COPYpackage-lock.json文件放入图片中；如果您已经在主机系统上以某种形式解决了依赖问题，则应该通过锁定文件将其转移到您的映像构建中。
我在 COPY package.json 命令下添加了 COPY package-lock.json 但是复制 package-lock.json 并不能解决问题我仍然遇到相同的 react-scripts not found 错误
也许你在本地使用较旧的 npm 版本，因为依赖错误是较新的东西。但你必须使用npm i --legacy-peer-deps 运行它，它应该可以工作。
还有RUN npm install 和RUN npm i -g npm 做一些完全不同的事情。一个安装本地依赖项，另一个安装全局 npm。
@TheWuif 我也尝试过几次，但都没有成功，我添加了一个更新，他在使用 --legacy-peer-deps 时发布了错误

【解决方案1】：

我认为我遇到的问题是我使用的是 node:alpine 基础映像，这导致了 Python 错误。现在我已将基础映像更改为 node:16.6.1，docker 映像构建良好。
