使用 docker 构建反应应用程序，同时在运行 npm install 时出错

Question

我正在使用 docker 构建一个 react 应用程序，但在 RUN npm install 时出现错误。我已经添加了ENV PATH和ENV CI，但是问题还没有解决。

这是我的 docker 文件：

FROM node:alpine

ENV PATH /app/node_modules/.bin:$PATH
ENV CI=true

WORKDIR /app
COPY package.json ./
COPY package-lock.json ./
RUN npm install
COPY ./ ./

CMD ["npm", "start"]

Docker 命令： docker build -t dockeruser/client .

终端响应：

Answer 1

显然，您的网络没有问题，但应用程序位于代理后面，如错误日志中所示。我能想到两个可能的修复方法。

首先，您可以设置代理配置

npm config set proxy http://proxy_host:port
npm config set https-proxy https://proxy.company.com:8080

或者其次，您可以清除您的代理

npm config rm proxy
npm config rm https-proxy

set HTTP_PROXY=null
set HTTPS_PROXY=null

然后就可以运行了

npm config list

查看是否有任何代理配置。

当然，我假设你知道你的代理地址是什么。
