Question

我想将babelized server.js文件导出到lib文件夹中。但是，当我构建Dockerfile时，在RUN babel server.js -d lib行中出现以下错误。我猜发生这种情况是因为找不到文件。我误会了吗？

错误消息

Step 11/14 : RUN babel server.js -d lib
 ---> Running in 68cef40456fb
/bin/sh: babel: not found
The command '/bin/sh -c babel server.js -d lib' returned a non-zero code: 127

Dockerfile

FROM node:10.16.3-alpine AS build
RUN mkdir -p /usr/src/app
WORKDIR /usr/src/app

ENV PATH="/app/node_modules/.bin:${PATH}"

COPY package.json ./
RUN npm install --silent --no-doc --no-ri

COPY server.js ./

RUN mkdir lib
RUN babel server.js -d lib

...

server.js

import App from './src/App';
import template from './src/template';
import { StaticRouter } from 'react-router-dom';
import express from 'express';
import path from 'path';
import React from 'react';
import ReactDOMServer from 'react-dom/server';

const app = express();

app.use('/assets', express.static(path.join(__dirname, 'dist')));

app.get('/*', (req, res) => {
  const context = {};
  const renderingResult = ReactDOMServer.renderToString(
      <StaticRouter location={req.url} context={context}>
        <App/>
      </StaticRouter>
  );

  let ssrPage = template('ssr test', '', renderingResult);
  res.send(ssrPage);
});

app.listen(3000);

生成Dockerfile时出现“ babel：未找到错误”
