我试图将我的Angular应用程序导出为npm模块以供其他应用程序使用,但遇到了一些困难.我无法在互联网上的任何其他地方找到此错误,而且我的智慧结束了.

我按照本教程:https://medium.com/@nikolasleblanc/building-an-angular-4-component-library-with-the-angular-cli-and-ng-packagr-53b2ade0701e

我使用ng-packagr将我的应用程序导出为npm模块.我可以从准系统测试应用程序上的本地文件夹成功安装它,但无法让它显示我的应用程序.

错误:

我正在尝试使用 react-bootstrap 创建表单，但无法弄清楚如何使用水平表单布局。下面是我的 signin.js 代码。

import React, {Component} from 'react';
import {reduxForm} from 'redux-form';
import {Form, FormGroup, FormControl, ControlLabel, Col, Button} from 'react-bootstrap';

class Signin extends Component{
    handleFormSubmit({username,password}){
        console.log(username,password);
    }
    render(){
        const {handleSubmit, fields: {username,password}}=this.props;
        return(
            <Form horizontal className="col-sm-6 offset-sm-3" onSubmit={handleSubmit(this.handleFormSubmit.bind(this))}>
                <FormGroup>
                    <Col componentClass={ControlLabel} sm={2}>
                        Username:
                    </Col>
                    <Col sm={10}>
                        <FormControl {...username} type="text" />
                    </Col>
                </FormGroup>
                <FormGroup>
                    <Col componentClass={ControlLabel} sm={2}>
                        Password:
                    </Col>
                    <Col sm={10}>
                        <FormControl {...password} type="password" />
                    </Col>
                </FormGroup>
                <FormGroup>
                    <Col>
                        <Button type="submit">Submit</Button>
                    </Col>
                </FormGroup>
            </Form>
        );
    }
}

export …
