我想在Mac OS上运行的节点4.2.2，我不理解为什么我每次收到此错误信息：events.js：141 throw er; //未处理的“错误”事件

events.js:141 
     throw er; // Unhandled 'error' event 
    ^
Error: spawn /Users/user/Documents/Projects/project-x/node_modules/gifsicle/vendor/gifsicle ENOENT

什么错？ 如果我运行“一饮而尽打造”有这样的输出：

正如@Andy所说，尽可能提供尽可能多的相关信息，以便您能够获得帮助。你有什么尝试？你写了什么代码？ –

尝试'sudo chown -R $（whoami）/ Users/user/Documents/Projects/project-x'来修复您的EACCES错误。 – lxe

ENOENT意味着spawn无法找到你正在寻找的二进制文件。确保你想要的任何东西spawn在你的道路上。

在这种情况下，您可能没有安装gifsicle。

我已经安装了gifsicle或imagemin-gifsicle，但它不起作用。 –

你好吗？你是怎么安装饮料的？该文件夹的权限是什么？ 'ls -l'会提供更多信息。 – Breedly

修复了这个问题。 资产的权限存在问题 - 如果吞噬不能获得所有资产。然后总是会显示一个错误。 我手动删除了资产。我认为我必须小心（出）“sudo” - 命令...

这不会涉及到您的错误，但该错误代码也可以运行，如果一个人在多个服务器上运行节点具有相同同时从他们的终端寻址。

检查是否有其他终端在同一端口上运行其他应用程序。当多个应用程序试图访问相同的端口时，会发生这种情况，它始终是FIFO。

祝你好运!!!

哦，是的，它解决了我的同样的问题 – yussan

它是什么端口？ – dmr

它是你的本地端口，如果localhost：\\ 3000已经启动并运行，你不能在同一个端口上运行另一个应用程序。你会得到上述错误。 –

你是否安装了imagemagick？

brew install imagemagick

先查看其他应用程序运行在同一个端口上可能是另一个节点应用程序。

要找到相同的端口使用当前运行的进程：

MAC：

你可以试试netstat的

netstat -anp tcp | grep 3000

对于OSX “酋长”，或者如果你的netstat不支持-p，使用lsof

lsof -i tcp:3000

然后杀死进程

kill pid

您可以尝试杀死所有节点过程中使用：

killall -9 node

我在工作中同样的错误在我的Mac Pro的预订。没有解决方案修复它。我终于通过重新启动计算机来解决问题。我经常不会在晚上关闭计算机并将其置于睡眠模式，因此如果您的计算机运行了很长时间，请尝试重新启动计算机，看看它是否适用于您。

所以它抛出一个错误，未处理的错误事件，这意味着你需要处理错误事件，在这个事件上添加函数并打印错误，你会发现原因和你的程序将正常工作。
