本文介绍了节点JS错误:ENOENT的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我跟着: 节点初学者书
使用另一篇SO帖子中的代码进行测试后:
After testing with the code from another SO post:
var Fs = require('fs');
var dirs = ['tmp'];
var index;
var stats;
for (index = 0; index < dirs.length; ++index)
{
try
{
stats = Fs.lstatSync(dirs[index]);
console.log(dirs[index] + ": is a directory? " + stats.isDirectory());
}
catch (e)
{
console.log(dirs[index] + ": " + e);
}
}
错误仍然存在:
错误:ENOENT，没有这样的文件或目录'tmp'
Error: ENOENT, no such file or directory 'tmp'
tmp上的权限为777.
The permissions on tmp are 777.
requestHandlers.js
var querystring = require("querystring"),
fs = require("fs");
function start(response, postData) {
console.log("Request handler 'start' was called.");
var body = '<html>'+
'<head>'+
'<meta http-equiv="Content-Type" '+
'content="text/html; charset=UTF-8" />'+
'<style>input{display: block; margin: 1em 0;}</style>'+
'</head>'+
'<body>'+
'<form action="/upload" method="post">'+
'<textarea name="text" rows="20" cols="60"></textarea>'+
'<input type="submit" value="Submit text" />'+
'</form>'+
'</body>'+
'</html>';
response.writeHead(200, {"Content-Type": "text/html"});
response.write(body);
response.end();
}
function upload(response, postData) {
console.log("Request handler 'upload' was called.");
response.writeHead(200, {"Content-Type": "text/plain"});
response.write("You've sent the text: "+
querystring.parse(postData).text);
response.end();
}
function show(response, postData) {
console.log("Request handler 'show' was called.");
fs.readFile("/tmp/test.jpg", "binary", function(error, file) {
if(error) {
response.writeHead(500, {"Content-Type": "text/plain"});
response.write(error + "\n");
response.end();
} else {
response.writeHead(200, {"Content-Type": "image/jpg"});
response.write(file, "binary");
response.end();
}
});
}
exports.start = start;
exports.upload = upload;
exports.show = show;
Index.js
var server = require("./server");
var router = require("./router");
var requestHandlers = require("./requestHandlers");
var handle = {}
handle["/"] = requestHandlers.start;
handle["/start"] = requestHandlers.start;
handle["/upload"] = requestHandlers.upload;
handle["/show"] = requestHandlers.show;
server.start(router.route, handle);
有些困惑，任何帮助表示赞赏.
A little stumped, any help appreciated.
推荐答案
"/tmp/test.jpg"不是正确的路径-此路径以/开头，它是根目录.
"/tmp/test.jpg" is not the correct path – this path starts with / which is the root directory.
在UNIX中，当前目录的快捷方式是.
In unix, the shortcut to the current directory is .
试试这个"./tmp/test.jpg"
