在for循环中调用异步函数

这是使用

.forEach()

paths.forEach(function( path ) {  fs.lstat( path, function(err, stat) {    console.log( path, stat );  });});

另外，您可以使用@Aadit建议的闭包：

for (var i = 0, c = paths.length; i < c; i++){  // creating an Immiedately Invoked Function expression  (function( path ) {    fs.lstat(path, function (error, stat) {      console.log(path, stat);    });  })( paths[i] );  // passing paths[i] in as "path" in the closure}
