Question

我已经按照不同开发人员发布的stackoverflow帖子的解决方案。但是，他们都没有帮助解决我遇到的问题。我做的事情很少是

卸载babel
安装babel-core，babel-cli
升级到节点v6.2.2
重新安装webpack
炸毁node_modules并再次运行npm install

以上所有内容从未修复此错误

这是我的package.json

{
  "name": "react-es6-setup",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "start": "webpack-dev-server"
  },
  "author": "",
  "license": "ISC",
  "dependencies": {
    "react": "^15.2.0",
    "react-dom": "^15.2.0"
  },
  "devDependencies": {
    "babel-core": "^6.10.4",
    "babel-loader": "^6.2.4",
    "babel-preset-es2015": "^6.9.0",
    "babel-preset-react": "^6.11.1"
  }
}

和webpack.config.js

module.exports = {
  entry: './main.js',
  output: {
    path: './',
    filename: 'index.js'
  },
  devServer: {
    inline: true,
    port: 3333
  },
  module: {
    loaders: [
        {
          test: /\.js$/,
          exclude: 'node_modules',
          loader: 'babel',
          query: {
            presets: [ 'es2015', 'react' ]
          }
        }
    ]
  }
}

和node_modules的目录列表

$ ls -l node_modules/ |grep react

Answer 1

让new_df.index.rename(['chrom','strand','abs_pos'], inplace=True) new_df.set_index('gene', append=True) new_df A B C chrom strand abs_pos gene chrom1 - 1234 geneA 1 1 1 + 5678 geneB 2 2 2 9876 geneC 3 3 3 chrom2 + 13579 geneD 4 4 4 8497 geneE 5 5 5 - 98765 geneF 6 6 6 76856 geneG 7 7 7 loaders: 'babel-loader'为我解决问题 -

使用npm

安装这些依赖项

webpack.config.js

在"babel-core": "^6.1.2", "babel-loader": "^6.1.0", "babel-plugin-transform-runtime": "^6.1.2", "babel-preset-es2015": "^6.1.2", "babel-preset-stage-0": "^6.1.2", "babel-runtime": "^5.8.0",文件中，请输入以下代码：

webpack.config.js

Answer 2

试试这个：

首先删除.next { bottom: 35px; }文件夹，然后删除

section {
  height:calc(100vh - 34px);
}

确保您的webpack.config.js具有：

node_module

然后npm init npm i webpack -S (Install Globally too) npm i babel-loader babel-preset-es2015 babel-preset-react babel-core -S npm i react react-dom -S`

Answer 3

我通过在Webpack配置中将加载程序更改为babel-loader而不是babel来解决此问题。

module: {
    rules: [
        {
            ...
            loader: 'babel',
            ...
        },
    ],
},

因为babel被转移到了babel-core
