The format of the URI could not be determined

[HZSamir]

What version of electron-installer-windows are you using?
0.2.0
What version of node and npm are you using?
v6.3.1 and 3.10.3
What operating system are you using?
Windows 10 (Latest build)
Can you compile the example app successfully?
Yes. Although the app doesn't start for whatever reason
What did you do? Please include the configuration you are using for electron-installer-windows.
Building the installer with the minimum options passed. Just an src and a dist folder.
electron-installer-windows --src ./OLS-Educ2-win32-x64/ --dest dist/installers/
What did you expect to happen?
An installer is born
What actually happened?
A huge error stack which boils down to this: "The format of the URI could not be determined".

I have seen in older issues that this issue stems from an incorrect icon path, however whether I pass one (http link to whatever icon) or not, the issue remains.

Here is the full text of the error:
`C:\Users\Samir\Documents\school5.electrify.dist>electron-installer-windows --src OLS-Educ2-win32-x64/ --dest dist/installers/
(node:1396) fs: re-evaluating native module sources is not supported. If you are using the graceful-fs module, please update it to a more recent version.

Thank you for taking the time.

I had same issue. I noticed projectUrl in .nuspec file is incorrect. After I added homepage to package.json, this issue disappeared.

[unindented]

Thanks @NikitaG for looking into it! I'll close the ticket then.

[mindvox]

What does the homepage property of package.json need to be set to in order to fix this issue?

[unindented]

It's required by Squirrel.Windows, which is the underlying library that generates the installer, as explained in the README. You can read their documentation here: https://github.com/Squirrel/Squirrel.Windows

[mindvox]

Thank you, but I have it set and still get the error?

[unindented]

@karlbateman It could be a malformed URL that you are passing to some other option. Can you paste your config file?

[mindvox]

package.json?

[unindented]

Yeah, if that's what you're using.

Try providing an email and homepage for your author field (it's the only difference I find when comparing with the example app provided with the package):

[mindvox]

Same problem

[unindented]

Try comparing with the example app, see what other differences you find. For example, you are not providing an icon, so maybe try that?

[mindvox]

Will do, I got it working with electron-builder.

[Wqrld]

bump, how do i need to set this up? im having the same problem with a config.json

{
  "dest": "dist/installers/",
  "iconUrl": "file:///C:/Users/werel/Desktop/programmeren/gamehub/gamehub/favicon.ico",
  "tags": [
    "Utility"
  ]
}

[joshuapinter]

@Wqrld Since your icon is a local file, you should use icon instead:

{
  "dest": "dist/installers/",
  "icon": "C:/Users/werel/Desktop/programmeren/gamehub/gamehub/favicon.ico",
  "tags": [
    "Utility"
  ]
}
