【问题描述】：

我正在尝试在 Mac OS 上运行节点 4.2.2，但我不明白为什么每次收到此错误消息：

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

    at doNTCallback2 (node.js:441:9)
    at process._tickCallback (node.js:355:17)
c12320:project-x user$ 

怎么了？ 如果我运行“gulp build”，就会有这个输出：

c12320:project-x user$ gulp build

如果我输入“gulp build”，这就是输出

【问题讨论】：

这里没有足够的信息来帮助您。你想做什么？运行gulp？什么任务？

正如@Andy 所说，尝试提供尽可能多的相关信息，以便获得帮助。你试过什么？你写了什么代码？

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

【参考方案1】：

ENOENT 表示spawn 无法找到您要查找的二进制文件。确保您尝试spawn 的内容在您的路径中。

在这种情况下，您可能没有安装 gifsicle。

【讨论】：

我已经安装了 gifsicle 或者 imagemin-gifsicle，但是还是不行。

你是怎么运行这个的？你是如何安装 gulp 的？该文件夹的权限是什么？ ls -l 将提供更多信息。

【参考方案2】：

解决了这个问题。 assets 的权限存在问题 - 如果 gulp 无法获取所有资产。然后总是会显示一个错误。 我手动删除了资产。我想我必须小心（退出）“sudo” - 命令...

【参考方案3】：

这与您的错误无关，但如果一个人从其终端同时在具有相同地址的多台服务器上运行节点，则该错误代码也可以运行。

【参考方案4】：

检查是否有任何其他终端在同一端口上运行其他应用程序。当多个应用程序尝试访问同一个端口时会发生这种情况，它总是 FIFO。

祝你好运！！！

【讨论】：

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。你得到上述错误。

解决了，这一行有语法错误 var port = process.env.port || 7000;

【参考方案5】：

你安装了 imagemagick 吗？

brew install imagemagick

【参考方案6】：

首先寻找其他应用程序在同一个端口上运行的可能是另一个节点应用程序。

要查找在同一端口上运行的当前进程，请使用：

MAC：

你可以试试netstat

netstat -anp tcp | grep 3000

对于 OSX "El Capitan" 或者如果您的 netstat 不支持 -p，请使用 lsof

lsof -i tcp:3000 

然后杀死进程

kill pid

您可以尝试杀死所有使用的节点进程：

killall -9 node

【参考方案7】：

我在 Mac Book Pro 上工作时遇到了同样的错误。没有一个解决方案可以解决它。我终于通过重新启动计算机解决了这个问题。我通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已经运行了很长时间，请尝试重新启动它，看看是否适合您。

【参考方案8】：

所以它抛出一个错误，未处理的'error'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，你会找到原因，你的程序会正常运行。
