运行命令Insufficient number of arguments or no entry found.
Alternatively, run 'webpack(-cli) --help' for usage info.
时出现错误npm run dev
,在此命令下我也收到一条错误消息,内容为ERROR in Entry module not found: Error: Can't resolve
,后跟路径。我不太确定为什么它找不到切入点,将不胜感激。
将整个项目上载到github以帮助提高可视性。 https://github.com/dustinm94/coding-challenge

webpack.config.js
和package.json
将始终位于项目的基本路径中,并且
节点命令应从此路径触发
您必须在webpack.config.js
和package.json
--watch
将自动在entry
的{{1}}对象中查找指定的文件,并继续观察其依赖关系图以在检测到更改时自动重新加载。您需要使用以下详细信息更新webpack.config.js
package.json
在监视模式下运行可能会导致性能问题,具体取决于您使用的硬件read more about it
将"scripts": {
"webpack" : "webpack", // invoke this command from npm run dev & npm run build
"dev": "npm run webpack -- --mode development --watch",
"build": "npm run webpack -- --mode production"
}
对象添加到您的entry
中。如果您没有覆盖输入对象,则默认情况下,Webpack会将webpack.config.js
对象指向'。/ src / index.js`。由于您未在项目中使用默认配置,因此webpack会引发错误
entry
要解决此错误,您需要使用目标ERROR in Entry module not found: Error: Can't resolve './src' in '/root/../coding_challenge'
文件覆盖entry
对象,如下所示
js
如果已完成上述更正,
module.exports = {
entry : "./frontend/src/index.js",
module: {
rules: [
{
test: /\.js$/,
exclude: /node_modules/,
use: {
loader: "babel-loader"
}
}
]
}
}
将以监视模式运行项目
npm run dev
将为您的项目生成生产版本
