我想在Mac OS上運行的節點4.2.2，我不理解爲什麼我每次收到此錯誤信息：events.js：141 throw er; //未處理的「錯誤」事件

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

什麼錯？ 如果我運行「一飲而盡打造」有這樣的輸出：

正如@Andy所說，儘可能提供儘可能多的相關信息，以便您能夠獲得幫助。你有什麼嘗試？你寫了什麼代碼？ –

ENOENT意味着spawn無法找到你正在尋找的二進制文件。確保你想要的任何東西spawn在你的道路上。

在這種情況下，您可能沒有安裝gifsicle。

我已經安裝了gifsicle或imagemin-gifsicle，但它不起作用。 –

你好嗎？你是怎麼安裝飲料的？該文件夾的權限是什麼？ 'ls -l'會提供更多信息。 – Breedly

修復了這個問題。 資產的權限存在問題 - 如果吞噬不能獲得所有資產。然後總是會顯示一個錯誤。 我手動刪除了資產。我認爲我必須小心（出）「sudo」 - 命令...

這不會涉及到您的錯誤，但該錯誤代碼也可以運行，如果一個人在多個服務器上運行節點具有相同同時從他們的終端尋址。

檢查是否有其他終端在同一端口上運行其他應用程序。當多個應用程序試圖訪問相同的端口時，會發生這種情況，它始終是FIFO。

祝你好運!!!

它是什麼端口？ – dmr

它是你的本地端口，如果localhost：\\ 3000已經啓動並運行，你不能在同一個端口上運行另一個應用程序。你會得到上述錯誤。 –

你是否安裝了imagemagick？

brew install imagemagick

先查看其他應用程序運行在同一個端口上可能是另一個節點應用程序。

要找到相同的端口使用當前運行的進程：

MAC：

你可以試試netstat的

netstat -anp tcp | grep 3000

對於OSX 「酋長」，或者如果你的netstat不支持-p，使用lsof

lsof -i tcp:3000

然後殺死進程

kill pid

您可以嘗試殺死所有節點過程中使用：

killall -9 node

我在工作中同樣的錯誤在我的Mac Pro的預訂。沒有解決方案修復它。我終於通過重新啓動計算機來解決問題。我經常不會在晚上關閉計算機並將其置於睡眠模式，因此如果您的計算機運行了很長時間，請嘗試重新啓動計算機，看看它是否適用於您。

所以它拋出一個錯誤，未處理的錯誤事件，這意味着你需要處理錯誤事件，在這個事件上添加函數並打印錯誤，你會發現原因和你的程序將正常工作。
