npm打包报错Module not found: Error: Can‘t resolve ‘.src/app.js‘ in ‘../Desktop/webpack-react-scaffold‘

报错信息如下：

ERROR in app
    Module not found: Error: Can't resolve '.src/app.js' in '/Users/allard/Desktop/webpack-react-scaffold'
    resolve '.src/app.js' in '/Users/allard/Desktop/webpack-react-scaffold'
      Parsed request is a module
      using description file: /Users/allard/Desktop/webpack-react-scaffold/package.json (relative path: .)
        Field 'browser' doesn't contain a valid alias configuration
        resolve as module
          looking for modules in /Users/allard/Desktop/webpack-react-scaffold/node_modules
            /Users/allard/Desktop/webpack-react-scaffold/node_modules/.src doesn't exist
          /Users/allard/Desktop/node_modules doesn't exist or is not a directory
          /Users/allard/node_modules doesn't exist or is not a directory
          /Users/node_modules doesn't exist or is not a directory
          /node_modules doesn't exist or is not a directory

主要看报错第一句如下：

     Module not found: Error: Can't resolve '.src/app.js' in '/Users/allard/Desktop/webpack-react-scaffold'，意思是在路径中没找到'.src/app.js'模块
     打开配置文件，没看出问题，重新在终端按路径查看文件，发现竟然缺少一个反斜杠“ / ”，这种问题每个开发断不了会遇到，还是需要在开发中尤其是配置文件写完，还是需要挨个认真再查看一遍避免出现不必要麻烦。
