Electron 无法在 windows 10 上写入文件

Question

使用 fs-extra 写入文件在 windows 10 上失败。outputFile method 应该在写入之前创建任何丢失的目录，但它会引发错误。不过，我知道下载目录已经存在。

Error: ENOENT: no such file or directory, open 'C:\Users\josh\Downloads18-01-13_15:14:11.png'

const fs = require('fs-extra')
const app = require('electron').remote.app
const moment = require('moment')

let dataURL = this.$.canvas.toDataURL()
let filename = moment().format('YYYY-MM-DD_HH:mm:ss') + '.png'
let buffer = new Buffer(dataURL.replace('data:image/png;base64', ''), 'base64')
let filepath = path.resolve(app.getPath('downloads'), filename)
fs.outputFile(filepath, buffer, err => {
    if (err) {
        console.error(err)
    }
})

您不能在 Windows.

的文件名中使用冒号“:”

来自Naming Files, Paths, and Namespaces：

Use any character in the current code page for a name, including Unicode characters and characters in the extended character set (128–255), except for the following:

The following reserved characters:

< (less than)

> (greater than)

: (colon)

" (double quote)

/ (forward slash)

\ (backslash)

| (vertical bar or pipe)

? (question mark)

* (asterisk)

Integer value zero, sometimes referred to as the ASCII NUL character.

Characters whose integer representations are in the range from 1 through 31, except for alternate data streams where these characters are allowed. For more information about file streams, see File Streams.

Any other character that the target file system does not allow.
