我知道这是一个形成问题的可怕方式，但我已经在这方面工作了几个小时并没有取得任何进展。昨晚一切都运行得很好，今天早上我从App Store获得了更新，让我重新启动，现在我的npm服务器（我正在努力学习React.js）无法正常工作。这是我的错误日志：

我试过了：

从node_modules目录中删除npm install webpack-dev-server并运行npm install
感谢评论，我能够解决。我尝试使用npm install webpack-dev-server重新安装。这没用。然后我尝试使用xyz/abc/node_modules/xyz/node_modules/abc/.bin/file并收到错误。它一直说webpack-dev-server之类的东西存在。移动并再试一次。我尝试了几次，最后从我的node_modules目录中删除了整个-bnot ([uint32]163)
目录并重新安装。这一切现在都有效。
顺便说一句，我使用Lynda.com的“React.js Essential Training”时使用了这个。仅包含可能存在此问题的其他人的此信息。
答案 1 :(得分：1)
不仅从webpack-dev-server目录中删除node_modules，而且从webpack-dev-middleware中删除。然后运行npm install webpack-dev-middleware和npm install webpack-dev-server。

您可以在This is my jquery code
$(document).ready(function(){
$('.reorder').on('click',function(){
$("ul.reorder-photos-list").sortable({ tolerance: 'pointer' });
$('.reorder').html('save reordering');
$('.reorder').attr("id","saveReorder");
$('#reorderHelper').slideDown('slow');
$('.img-w').attr("data-src","");
$('.img-w').css("cursor","move");
$("#saveReorder").click(function( e ){
if( !$("#saveReorder i").length ){
$(this).html('').prepend('saving...');
$("ul.reorder-photos-list").sortable('destroy');
$("#reorderHelper").html( "Reordering Photos - This could take a moment. Please don't navigate away from this page." );
var h = [];
$("ul.reorder-photos-list li").each(function() { h.push($(this).attr('id') ) });
$.ajax({
type: "POST",
url: "{{route("settings.updatephotos")}}",
data: {ids: " " + h + ""},
success: function(){
window.location.reload();
}
});
return false;
}
e.preventDefault();
});
});
})
配置中将此选项设置为false：
webpack-dev-server =＆gt; quiet: true

根据需要设置webpack webpack cli webpack-dev-server，然后从项目中删除package-lock.json文件和节点模块文件夹，并在cmd中打开项目目录并运行npm install
