I meet the same problem. The abs_src is "C:\Users\33028\.cargo\bin\cargo-tauri.exe", but the abs_dest is "D:\project\sars-mobile\src-tauri". The error is from cargo-mobile>src>util>path>common_root: unreachable!("abs_src and abs_dest have no common root"); If I move my project to disk C, the error disappared. I think I should not store project to DISK C, so is this a BUG? fn common_root(abs_src: &Path, abs_dest: &Path) -> PathBuf { println!("abs_src: {:?}", abs_src); println!("abs_dest: {:?}", abs_dest); let mut dest_root = abs_dest.to_owned(); loop { if abs_src.starts_with(&dest_root) { return dest_root; } else if !dest_root.pop() { unreachable!("abs_src and abs_dest have no common root"); } } }

I'm getting the same error in windows when my project isn't on disk C:

When the project is on C: - one of the messages says

Info "C:\\Program Files\\nodejs\\node.exe" relative to "C:\\proj\\thingy\\src-tauri" is "..\\..\\..\\Program Files\\nodejs\\node.exe"

So looks like it's trying to get a relative path from your project to nodejs executable.

On windows, if they are both on different disks - this is impossible so it panics.

Could any of you who face this issue provide the directory structure of your drive, if possible with .gitignore if any exists, for example:

C:/
  |_ some-dir
    |_ .gitignore
    |_ some-another-dir
      |_ my-tauri-app

[bdew]

Could any of you who face this issue provide the directory structure of your drive, if possible with .gitignore if any exists, for example:

As i said above, the problem happens when your node executable is not on the same drive as your project.

For me tauri project is in G:\ruststuff\tauritest node is C:\Program Files\nodejs\node.exe

I have a gitignore in G:\ruststuff\tauritest (the default one created by yarn create tauri-app --alpha --template react-ts)

There is no common root between different disks and it crashes with that "entered unreachable code" error.

If the project is anywhere on C: it works correctly.

[amrbashir]

I have a similar project structure and it worked fine, could you maybe run with --verbose flag, maybe it has more info

[bdew]

@amrbashir are you on windows and is your project on a different disk than your nodejs.exe ?

The code that panics is here - https://github.com/tauri-apps/cargo-mobile2/blob/dev/src/util/path.rs#L130-L164

To me it looks like it assumes a posix filesystem that has one common root for everything, on windows it's not true so it gets into that "unreachable" branch.

[amrbashir]

@amrbashir are you on windows and is your project on a different disk than your nodejs.exe ?

yes, also not sure why it is trying to find nodejs.exe.

Finally, I can reproduce it, the issue seems to only happen with yarn and cargo as well, will look into this.

[bdew]

@amrbashir are you on windows and is your project on a different disk than your nodejs.exe ?

yes, also not sure why it is trying to find nodejs.exe.

I think it's this code: https://github.com/tauri-apps/tauri/blob/5a19147b06d03e7877ed2291e2bc6ff622aa939f/tooling/cli/src/mobile/init.rs#L107-L118

When running from yarn i think it loads the cli as a node module? (through @tauri-apps/cli npm package which then loads @tauri-apps/cli-win32-x64-msvc) so your argv[0] is node.exe

[amrbashir]

Thanks @bdew for your help, I made a PR to fix this.
