Nodejs fs.js TyperError，适用于Mac，但不适用于Windows
我得到这个错误：
fs.js:81 throw new TyperError('Expected options to be either an object or a string. ) 它不是在我的Mac上做，但它在Windows上。
我不知道如何解决这个问题，我不知道nodejs
这是我的代码的全部，不知道问题的地方，因为我在几个地方使用fs
// load modules var request = require('request'); // create text file on disk var filename = Date.now(); // date for filename var fs = require('fs'); // code to make file fs.writeFile("" + filename + ".csv", "", function(err) { if (err) { return console.log(err); } console.log("The file " + filename + ".csv was created!"); }); // create text file on disk end // read urls file var fs = require("fs"); fs.readFile("urls.txt", function(err, f){ var urls = f.toString().split('\n'); console.log("Finished reading URLs file...") // use the array // loop through every file for (var i = 0; i < urls.length; i++) { console.log('\x1b[32m%s\x1b[0m',"Loaded to memory -> ",urls[i]); setTimeout(main, i * 300, urls[i], i, urls.length); }// end loop }); // read urls end console.log("Loop done..."); function main (url, lineNumber, totalLines) { // get request to url request(url, function (error, response, body) { if (typeof response == 'undefined' || response == null) { return; } if (response.statusCode !== 200) { return; } // console.log('error:', error); // Print the error if one occurred console.log('\x1b[2m%s\x1b[0m','StatusCode for ' + url + ' ->', response && response.statusCode); // Print the response status code if a response was received // console.log('body:', body); // Print the HTML for the Google homepage. //define my regex var myregex = /href="([^"]*contact[^"]*)"/gi; // make sure it's not null if (typeof body == 'undefined' || body == null || body.match(myregex) == 'undefined' || body.match(myregex) == null){ return; } // find contact urls using regex and puts it in array results = body.match(myregex).slice(1); // console.log(results); //loop through arrays of regexes for (var x = 0; x < results.length; x++) { //remove href from string results[x] = results[x].replace('href="', ''); results[x] = results[x].replace('"', ''); //add root domain if it doesn't have it if (results[x].match(/http/) == null) { //trim to root trim = RegExp(/(http:\/\/|https:\/\/).+?\//); console.log("Has no root -> " + url); url = url.match(trim)[0]; console.log("Trimming domain...

appendFileSync不接受callback作为参数。 将其replace为appendFile 。 参考： https ： //nodejs.org/api/fs.html#fs_fs_appendfile_file_data_options_callback
