每当文件更改时,我都试图读取该文件。文件更改是webpack输出。即使更改后的文件不是空文件,它在返回空字符串时也会产生不一致的结果。我已附上screenshot of the logs。
var watcher = chokidar.watch(path.resolve(__dirname, '../../dist/main.root.js'), /^\./, {persistent : true, usePolling: true, interval: 1000})
watcher
.on('add', path => {
// fileAdded(path)
console.log(`File ${path} has been added`, Date.now())
})
.on('change', path => {
console.log(`File ${path} has been changed`)
fileChanged(path)
})
function fileChanged (path) {
fs.readFile(path, 'utf8', (err, data) => {
if (err) {
console.error(err)
} else {
var target = data
console.log('***target***', typeof target, target)
console.log('***path***', path)
}
})
}

问题在于chokidar不会等待文件写入完成,除非它是通过配置定义的。查看chokidar-get-started,最重要的是:
awaitWriteFinish: {
stabilityThreshold: 2000,
pollInterval: 100
}
此设置应该可以解决您的问题。
