的WebPack决心扩展导致在构建时未找到错误文件名

Question

我在我的WebPack配置以下决心键：

resolve: { 
     extensions: ["js", "jsx"] 
} 

运行webpack --display-error-details后，我看到：

ERROR in multi main Module not found: Error: Cannot resolve 'file' or 'directory' ./src/index.js in /Users/me/Desktop/coin-web resolve file
/Users/me/Desktop/coin-web/src/index.jsjs doesn't exist /Users/me/Desktop/coin-web/src/index.jsjsx doesn't exist resolve directory
/Users/me/Desktop/coin-web/src/index.js/package.json doesn't exist (directory description file)
/Users/me/Desktop/coin-web/src/index.js is not a directory (directory default file) [/Users/me/Desktop/coin-web/src/index.jsjs] [/Users/me/Desktop/coin-web/src/index.jsjsx]

如果我删除完全从配置中获取密钥resolve，它会成功建立。然而，我很好奇为什么它的包含导致这个jsjs,jsjsx业务。

我想这是因为它应该是：

resolve: { 
    extensions: [".js", ".jsx"] 
} 

（包括周期）
