反应：找不到模块：无法解析“ react-html-parser”

Question

我正在尝试react-html-parser在我的docker容器’client’中安装：

docker-compose.yml
client/
      Dockerfile-dev
      node_modules/
      src/   
         components/
                   Seeds.jsx

并尝试在这里导入：

Seeds.jsx

import React, { Component } from 'react';
import ReactHtmlParser, { processNodes, convertNodeToElement, htmlparser2 }
from 'react-html-parser';
import axios from 'axios';

'axios'并且'react'可以安装，但是不是'react-html-parser'。控制台将错误记录给我：

index.js:1437 ./src/components/Seeds.jsx
Module not found: Can't resolve 'react-html-parser' in '/usr/src/app/src/components'

package.json

{
  "name": "client",
  "version": "0.1.0",
  "private": true,

    "axios": "^0.18.0",

  },

  },

  },

  ],

  }
}

Dockerfile开发

# base image
FROM node:11.6.0-alpine

# set working directory
WORKDIR /usr/src/app

# add `/usr/src/app/node_modules/.bin` to $PATH
ENV PATH /usr/src/app/node_modules/.bin:$PATH

# install and cache app dependencies
COPY package.json /usr/src/app/package.json

RUN npm install --silent
RUN npm install react-scripts@2.1.2 -g --silent

# start app
CMD ["npm", "start"]

docker-compose.yml

  client:
    build:
      context: ./services/client
      dockerfile: Dockerfile-dev
    volumes:
      - './services/client:/usr/src/app'
      - '/usr/src/app/node_modules'
    ports:
      - 3000:3000
    environment:
      - NODE_ENV=development
      - REACT_APP_WEB_SERVICE_URL=${REACT_APP_WEB_SERVICE_URL}
    depends_on:
      - web

我在node_modules文件夹中找不到模块…

我在这里想念什么？

Answer 1

当您的docker-compose.yml文件说：

volumes:
  - '/usr/src/app/node_modules'

您是在告诉Docker您的node_modules目录包含关键数据，这些关键数据需要在容器运行期间保持不变。首次启动容器时，它将从映像中填充该容器，但是由于该目录包含关键数据，因此即使您尝试npm install添加其他模块，Docker也将永远不会再次对其进行更新。

对于近期的解决方法，这对于docker-compose stop; docker-compose rm; docker-compose up --build您的容器就足够了。删除现有容器（及其匿名卷）很重要。
