# Frequently Asked Questions ## Why does the menubar appear when running in development mode, but disappear when packaged? Based on [a comment from **@MarshallOfSound**](https://github.com/electron-userland/electron-packager/issues/553#issuecomment-270805213): When you're running in "development mode" (for example, `electron /path/to/app`), Electron uses the `default_app` codepath to run your app, which also provides a default menubar. When the app is packaged, Electron runs your app directly. To have a menubar that's consistent between development and packaged modes, you'll need to [define it yourself](https://electron.atom.io/docs/api/menu/). ## Why isn't my `ignore` option working? As stated in the documentation for [`ignore`](https://github.com/electron-userland/electron-packager/blob/master/docs/api.md#ignore), it uses "[one] or more additional [regular expression](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guide/Regular_Expressions) patterns. […] Please note that [glob patterns](https://en.wikipedia.org/wiki/Glob_%28programming%29) will not work." ## Why isn't the relative path in my app code working? To make a path work in both development and packaged mode, you'll need to generate a path based on the location of the JavaScript file that is referencing the file. For example, if you had an app structure like the following: ``` AppName ├── package.json ├── data │   └── somedata.json └── src    └── main.js ``` In `src/main.js`, you would access `data/somedata.json` similar to this: ```javascript const path = require('path'); const jsonFilename = path.resolve(__dirname, '..', 'data', 'somedata.json'); console.log(require(jsonFilename)); ``` ## How do I set an icon on Linux? The docs for [`icon`](https://github.com/electron-userland/electron-packager/blob/master/docs/api.md#icon) already show how to set an icon on your `BrowserWindow`, but your dock/taskbar may not use that and instead use the `Icon` value in your `.desktop` file. The [Linux distributable creators](https://github.com/electron-userland/electron-packager#distributable-creators) can help you set/distribute the appropriate icon in that case.
