Question

在node_modules中我找不到“验证程序”包，但是我不明白为什么它没有与dockerfile一起安装在npm中。这是我的项目。

DockerFiles

import React, { Component } from 'react';

export default class Create extends Component {
    constructor(props) {
        super(props);
        this.onChangeFirstname = this.onChangeFirstname.bind(this);
        this.onChangeLastname = this.onChangeLastname.bind(this);
        this.onChangeMessage = this.onChangeMessage.bind(this);
        this.onSubmit = this.onSubmit.bind(this);

        this.state = {
            person_firstname: '',
            person_lastname: '',
            message:''
        }
    }
    onChangeFirstname(e) {
      this.setState({
        person_firstname: e.target.value
      });
    }
    onChangeLastname(e) {
      this.setState({
        person_lastname: e.target.value
      })  
    }
    onChangeMessage(e) {
      this.setState({
        message: e.target.value
      })
    }

    onSubmit(e) {
      e.preventDefault();
      console.log(`The values are ${this.state.person_firstname}, ${this.state.person_lastname}, and ${this.state.message}`)
      this.setState({
        person_firstname: '',
        person_lastname: '',
        message: ''
      })
    }

    render() {
        return (
            <div style={{marginTop: 10}}>
                <h3>Contact Form</h3>
                <form onSubmit={this.onSubmit}>
                    <div className="form-group">
                        <label>First Name:  </label>
                        <input type="text" className="form-control" 
                            onChange={this.onChangeFirstName}/>
                    </div>
                    <div className="form-group">
                        <label>Last Name: </label>
                        <input type="text" className="form-control"
                            onChange={this.onChangeLastname}/>
                    </div>
                    <div className="form-group">
                        <label>Message: </label>
                        <textarea className="form-control"
                            onChange={this.onChangeMessage}>
                        </textarea>
                    </div>
                    <div className="form-group">
                        <input type="submit" value="Submit" className="btn btn-primary"/>
                    </div>
                </form>
            </div>
        )
    }
}

package.json

FROM node:latest
WORKDIR /app
ADD restapi/* /app/
RUN npm install -g nodemon && \
npm install -g
RUN npm install -g validator    
EXPOSE 3000   
CMD ["nodemon"]

docker-compose

"dependencies": {
    "body-parser": "^1.18.3",
    "cookie-parser": "^1.4.4",
    "debug": "^4.1.1",
    "express": "^4.16.4",
    "firebase-admin": "^7.0.0",
    "jade": "^1.11.0",
    "kafka-node": "^4.0.2",
    "mongoose": "^5.4.18",
    "mongoose-float": "^1.0.3",
    "morgan": "^1.9.1",
    "bcryptjs": "^2.4.3",
    "jsonwebtoken": "^8.1.0",
    "validator": "^12.1.0"
  }

docker-compose返回此错误：

version: "3"
services:
  mongodb:
    image: mongo:latest
    container_name: mongo1
    ports:
      - 27017:27017
  restapi:
    build: .
    image: restapi
    container_name: restapi1
    depends_on:
      - mongodb

    volumes:
      - //c/Users/Halnap/restapi_project/restapi:/app
    ports:
      - 3000:3000

也许我应该在package-lock.json中添加验证器？在package-lock.json中缺少验证器和bcryptjs（已从dockerfiles中删除）中，为什么不与npm一起添加？在执行过程中，它是根据Powershell + Validator@12.1.0的屏幕添加的在0.739秒内添加了2位贡献者的1个程序包

在DockerFiles中，validator软件包正在全局安装，而不是在当前目录中安装。在以下命令中可以看到：npm install -g validator。您可以看到nodemon也在全局安装，也没有出现在依赖项的package.json列表中。

如果要在本地安装此软件包，请运行npm i -S validator。

找不到模块的验证器
