ENOENT:没有这样的文件或目录. [英] ENOENT: no such file or directory .?

问题描述

这是发布数据和文件时出现的错误. 我遵循了"academind"教程来构建Restful API服务，我也一直在寻找此类错误的答案，但对我没有任何帮助.

This is error which am getting while post data and file. I have followed 'academind' tutorial for building Restful API services, also i have been searching answer for this type of errors but nothing works for me.

我使用"multer"上传文件

Am using "multer" to upload file

该文件夹中的文件夹上载"可用，但显示为

The folder 'uploads' available in the folder but it shows

ENOENT:无此类文件或目录，打开'D:\ project \ uploads \ 2018-01-24T07:41:21.832Zcheck.jpg'"

ENOENT: no such file or directory, open 'D:\project\uploads\2018-01-24T07:41:21.832Zcheck.jpg'"

product.js中的

推荐答案

:

在new Date().toISOString()之后添加replace()，将:" 更改为可接受的字符.

in product.js:

After new Date().toISOString() add replace() to change ":" to an accepted character.

Windows操作系统不接受带有:"

Windows OS doesn't accept files with a ":"

Youtube上的人正在使用MAC OS

The person on Youtube is using MAC OS

例如

new Date().toISOString().replace(/:/g, '-')
