reactjs - Babel 7 升级 : @babel/helper-module-imports

Question

我正在升级 Babel 6 项目 (6.14.0)，在运行 Babel 升级程序 (npx babel-upgrade --write) 后我遇到了问题

我已经运行了 npm install @babel/helper-module-imports 但是，似乎根本没有解决任何问题。

我收到的错误消息如下:(但是对于每个单独的组件......其中有很多)

./src/components/TableData/index.js 中的错误模块构建失败:错误:src/components/TableData/index.js:此 API 已被删除。如果你在 Babel 7 中寻找这个功能，你应该导入 '@babel/helper-module-imports' 模块并使用从该模块公开的函数，例如 'addNamed' 或 'addDefault'。

关于如何解决这个问题的任何指南？或者应该去哪里看？ (我已经安装了这个包，但没有运气......尝试删除 package.lock.json 和 node_modules，没有运气。)

至于表文件，这是一个快照。奇怪的是它过去在升级前运行良好，尽管我们运行了 linter 并添加了片段 short-syntax <>。不确定那是否是精确定位区域。

Table Index content

import React, { Component } from "react";
import ReactDOM from "react-dom";
import axios from 'axios';
import { BACKEND_ROOT_URL } from "../../constants";
import ApplicationsTable from "./applicationsTable";    

class TableData extends Component {
  constructor(props) {
    super(props);
    this.state = {
      data: [],
      total: 0,
      isError: false,
      errorMessage: "",
    };
    this.componentDidMount = this.componentDidMount.bind(this);
  }

  componentDidMount() {
    this.getData();
  }

  getData() {
    const currn = this;
    axios
      .get(`${this.props.url}/all`)
      .then((response) => {
       currn.setState({
            data: response.data,
            total: response.data.length,
          });
      })
      .catch(function (error) {
        currn.setState({
          isError: true,
          errorMessage: error.response.data.message,
        });
      });
  }


  render() {
    return (
      <div className="bx--row">
        <div className="bx--col-lg-12">
          {this.state.isError == true ? (
            <h3 className="bx-error-404">{`Error: ${this.state.errorMessage}`}</h3>
          ) : (
            <>
              <ApplicationsTable
                data={this.state}
              />
            </>
          )}

    );

我能够解决它，问题是包:babel-plugin-react-transform

它是这样被导入的，删除/更新到热加载器解决了它。

希望这对发现这种情况的人有所帮助。
