Javascript 当相同的代码在其他windows计算机上执行时，为什么gulp.watch不能在windows计算机上运行？

我正在帮助一位远程同事在他们的Windows 10计算机上安装gulp，但遇到了一个问题，gulp中的手表功能根本无法工作

其他的“吞咽”功能运行良好，但手表特别是在屏幕上没有任何错误地挂起

为了确保代码中没有遗漏任何内容，我做了一个简单的测试gulpfile，以确保这不是由于其他原因造成的

gulpfile.js

var gulp = require("gulp");
var fs = require('fs');
var compareToPreviousRead = require("./fileReaderTest.js");

gulp.task("watch", function(){
    return gulp.watch("Test.txt", async function(){
        var diff = await compareToPreviousRead();
        console.log(`Diff: "${diff}", Time: "${new Date().toGMTString()}"`);
        Promise.resolve(true);
    });
});

var fs = require('fs');

var readTestFile = () => new Promise(resolve => {
    fs.readFile('Test.txt', 'utf8', (err, contents) => resolve(contents));
});

var originalValue = "";

var compareToPreviousRead = () => new Promise(resolve => {
    readTestFile().then(updatedValue => {
        var diff = updatedValue.replace(originalValue, "");
        originalValue = updatedValue;
        resolve(diff);
    });
});

module.exports = compareToPreviousRead

fileReaderTest.js

var gulp = require("gulp");
var fs = require('fs');
var compareToPreviousRead = require("./fileReaderTest.js");

gulp.task("watch", function(){
    return gulp.watch("Test.txt", async function(){
        var diff = await compareToPreviousRead();
        console.log(`Diff: "${diff}", Time: "${new Date().toGMTString()}"`);
        Promise.resolve(true);
    });
});

var fs = require('fs');

var readTestFile = () => new Promise(resolve => {
    fs.readFile('Test.txt', 'utf8', (err, contents) => resolve(contents));
});

var originalValue = "";

var compareToPreviousRead = () => new Promise(resolve => {
    readTestFile().then(updatedValue => {
        var diff = updatedValue.replace(originalValue, "");
        originalValue = updatedValue;
        resolve(diff);
    });
});

module.exports = compareToPreviousRead

我还包括一些PowerShell脚本，用于从同一目录安装和运行应用程序。 有人也可以在同一个目录中手动编辑一个名为“Test.txt”的文件（仅附加到该文件），这样gulp任务就可以正常工作
