我正在使用axios通过React.js构建一个简单的天气应用程序。我刚完成代码,但是有问题。当我启动该应用程序时,它根本无法工作,并且看到一个引用错误axios is not defined
。
这是我的webpack.config.js文件:
module.exports = {
entry: './public/app/app.jsx',
output: {
path: __dirname,
filename: './public/js/bundle.js'
},
externals: ['axios'],
resolve: {
root: __dirname,
alias: {
OpenWeatherMap: 'public/components/OpenWeatherMap.jsx',
Main: 'public/components/Main.jsx',
Nav: 'public/components/Nav.jsx',
Weather: 'public/components/Weather.jsx',
WeatherForm: 'public/components/WeatherForm.jsx',
WeatherMessage: 'public/components/WeatherMessage.jsx',
About: 'public/components/About.jsx'
},
extensions: ['', '.js', '.jsx']
},
module: {
loaders: [{
loader: 'babel-loader',
query: {
presets: ['react','es2015', 'stage-0']
},
test: /\.jsx?$/,
exclude: /(node_modules|bower_components)/
},{
loader: 'json-loader',
test: /\.json?$/
}]
}
};
和package.json文件:
{
"name": "weather",
"version": "1.0.0",
"description": "Simple Weather App",
"main": "ext.js",
"scripts": {
"test": "echo \"Error: no test specified\" && exit 1"
},

}
}
最佳答案
我知道这似乎很明显,但是请确保在文件顶部有一个指向正确axios的引用或进行安装
https://www.npmjs.com/package/axios
<script src="https://unpkg.com/axios/dist/axios.min.js"></script>
