我当前正在启动NodeJS应用程序,我想检查文件夹是否存在操作:
[Node] log/20190405 ----------created the folder log/20190405/2019040500.log-----------------
[Node] fs.js:885
[Node] return binding.mkdir(pathModule._makeLong(path),
[Node] ^
[Node]
[Node] Error: ENOENT: no such file or directory, mkdir 'log/20190405'
[Node] at Object.fs.mkdirSync (fs.js:885:18)
[Node] at fs_1.default.access (/home/lordrauf/Documents/myproject/dist/util/logger.js:25:30)
[Node] at FSReqWrap.oncomplete (fs.js:135:15)
奇怪的是,我不确定该文件夹位于何处,但是对以下代码段的检查失败:
function checkFilePromise() {
return new Promise((resolve, reject) => {
fs.access(`log/${format("yyyyMMdd", new Date())}`, fs.constants.F_OK, (err) => {
console.log(`log/${format("yyyyMMdd", new Date())} ${err ? `----------created the folder ${logName}-----------------` : '----------log folder exists----------'}`);
if (err) {
fs.mkdirSync(`log/${format("yyyyMMdd", new Date())}`);
console.log(err)
reject(err)
} else {
resolve(true)
}
});
})
}
如果有人知道如何解决此问题,请帮助我。任何建议表示赞赏。谢谢。
