問題描述

我正在開發一個電子應用程序，在該應用程序中，我使用 child_process.exec 執行 shell 命令.我運行的命令之一是 npm run start;這在開發環境中完美運行，但是當我為生產構建應用程序時，所有 npm 命令都失敗并顯示以下錯誤:

I'm working on an electron app and within the app, I execute shell commands using child_process.exec. One of the commands I run is npm run start; this works perfectly in a dev environment but when I build the application for production all npm commands fail with showing the following error:

   Error: Command failed: npm run start
   /bin/sh: npm: command not found


    at ChildProcess.exithandler (child_process.js:287)
    at emitTwo (events.js:126)
    at ChildProcess.emit (events.js:214)
    at maybeClose (internal/child_process.js:925)
    at Socket.stream.socket.on (internal/child_process.js:346)
    at emitOne (events.js:116)
    at Socket.emit (events.js:211)
    at Pipe._handle.close [as _onclose] (net.js:554)

我嘗試通過運行以下命令以調試模式運行應用程序 open MyApp.app/Contents/MacOS/MyApp 并且 npm 命令成功運行且沒有錯誤.

I tried running the application in debug mode by running the following command open MyApp.app/Contents/MacOS/MyApp and the npm commands run successfully with no errors.

可能是什么問題?

推薦答案

打包后的應用程序中$PATH環境變量錯誤的問題，在開發中是可以的，因為應用程序是從終端啟動的，它可以訪問$BASH 配置文件.

The issue that the environment variable of $PATH is wrong inside the packaged app, it works in development because the application is launched from the terminal which gives it access to the $BASH profile.

為了解決這個問題，我使用了這個包 fix-path.我安裝了軟件包并在文件頂部添加了以下代碼段

To solve this problem I used this package fix-path. I installed the package and added the following snippet at the top of the file

if (process.env.NODE_ENV === 'production') {
  const fixPath = require('fix-path');

  fixPath();
}
