ERROR in multi ./main.js . Module not found: Error: Can't resolve '/home/user/workspace/webpack'

Question

我在捆绑 2 个独立的 javascript 文件时遇到问题。

index.html

<html>
<head>
<title>experiment</title>
<script src="main.js"></script>
<script src="new.js"></script>
</head>
<body>
<form>
<button onclick="firstButton();">firstButton</button>
<button onclick="secondButton();">secondtButton</button>
</form>
</body>
</html>

main.js

function firstButton() {

console.log("First Button");    
}

new.js

function secondButton(){
    alert("Second Button");
}

webpack.config.js

module.exports = {
  entry: './main.js',
  output: {
    filename: './bundle.js'
  }
};

当运行 webpack . 命令然后在终端上出现此错误

Hash: 8a3cc31d526703c3b9fa
Version: webpack 2.5.1
Time: 88ms
      Asset     Size  Chunks             Chunk Names
./bundle.js  2.91 kB       0  [emitted]  main
   [0] ./main.js 57 bytes {0} [built]
   [1] multi ./main.js . 40 bytes {0} [built]

ERROR in multi ./main.js .
Module not found: Error: Can't resolve '/home/user/workspace/webpack' in '/home/user/workspace/webpack'
 @ multi ./main.js .

我也试过这个webpack.config.js

const config = {
  entry: {
    a : './main.js' ,
    b : './new.js'
  } ,
   output: {
    filename: 'bundle.js',
    path: '/home/user/workspace/webpack'
  }
};

module.exports = config;

这是我遇到的错误..

webpack CLI 的任何参数都被解释为入口点（参见 Command Line Interface (CLI)）。当你运行:

webpack .

. 对应于当前目录，webpack 尝试从中解析一个模块，应该用作入口点。

您已经在 webpack 配置中配置了入口点，因此您应该运行不带任何参数的 webpack：

webpack

ERROR in multi ./main.js . Module not found: Error: Can't resolve '/home/user/workspace/webpack'

ERROR in multi ./main.js . Module not found: Error: Can't resolve '/home/user/workspace/webpack'
