Common Issues

Blank screen on builds, but works fine on serve

This issue is likely caused when Vue Router is operating in history mode. In Electron, it only works in hash mode. To fix this, edit your src/router.(js|ts):

// src/router.(js|ts)
export default new Router({
-  mode: 'history',
+  mode: process.env.IS_ELECTRON ? 'hash' : 'history',

This will have the router operate in hash mode in Electron builds, but won't affect web builds.

electron:serve freezes on Launching Electron...

Often this issue is caused when Vue Devtools fails to install. This may happen if Vue Devtools cannot be accessed in your location (eg. China). To fix this, you may have to disable Vue Devtools by removing the following lines from your src/background.(js|ts) file:

if (isDevelopment && !process.env.IS_TEST) {
  // Install Vue Devtools
  await installVueDevtools()

Strict mime-type error when running a built app


As of v1.0.0-rc.5, this tag is no longer necessary. You can remove it if you wish.

This is likely caused because you are missing code in your public/index.html file. To add it, simply run vue invoke electron-builder. This will re-invoke the generator of VCP Electron Builder. Any missing code will be detected and added automatically. If you would not like to re-invoke the generator, you can paste this code into the top of the <head> of your public/index.html:

<% if (BASE_URL === './') { %><base href="app://./" /><% } %>

Exceptions in async functions not getting logged to console

This bug can be fixed by adding the following code to the entrypoint of your Vue App src/main.js:

process.on('unhandledRejection', error => {

See #118 for more details. Thanks to dspangenberg for the fix.

Electron not opening on Node v11

Make sure you are using Electron v2.0.14+ or v3.0.10+. Also, make sure Node is v11.2.0+. See #107 (comment) for more details.

Other issues

Many issues can be solved by re-invoking the generator of Vue CLI Plugin Electron Builder. This allows it to add newer code to your project files. You may need to do this after upgrading the plugin.

# In the root dir of your project
vue invoke electron-builder
