Javascript events.js:141投掷者；//未处理'；错误'；事件

我试图在Mac OS上运行node 4.2.2，但我不明白为什么每次收到此错误消息时：

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

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

怎么了？ 如果我运行“gulp build”，则有以下输出：

如果我输入“gulp build”，这就是输出。

enoint意味着

spawn

无法找到您要查找的二进制文件。确保您试图生成的内容都在您的路径中

---

在这种情况下，您可能没有安装gifsicle。

修复了该问题。如果gulp无法获取所有资产，则资产的权限出现问题。然后总是会显示一个错误。

---

我手动删除了资产。我想我必须小心使用“sudo”-命令…

这与您的错误无关，但是如果一个人在多台服务器上同时从他们的终端运行同一地址的节点，那么该错误代码也会运行

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同一端口时，会发生这种情况，该端口始终是FIFO

---

祝你好运

是否安装了imagemagick

brew install imagemagick

---

首先查找在同一端口上运行的其他应用程序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 

然后终止进程

kill pid

您可以尝试终止所有节点进程使用：

我在Mac Book Pro上工作时也犯了同样的错误。没有一个解决方案能解决这个问题。我终于通过重启电脑解决了这个问题。我通常不会在夜间关闭计算机并将其置于睡眠模式，因此如果您的计算机已运行很长时间，请尝试重新启动计算机，看看是否对您有效。

因此它会引发一个错误，即未经处理的“错误”事件，这意味着您需要处理错误事件，在此事件上添加函数并打印错误，您将找到原因，程序将正常运行。

此处没有足够的信息帮助您。你想干什么？大口喝？什么任务？正如@Andy所说，尽可能多地提供相关信息，以便获得帮助。你试过什么？您编写了什么代码？请尝试

sudo chown-R$（whoami）/Users/user/Documents/Projects/project-x

来修复您的EACCES错误。我已经安装了gifsicle或imagemin gifsicle，但它不起作用。您是如何运行它的？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。这是您的本地端口，如果localhost:\\3000已启动并正在运行，您无法在同一端口上运行其他应用程序。您得到了上面的错误。解决了它，在这一行var port=process.env.port | | 7000；
