Windows dev build: Tauri version mismatch, IPv6 localhost timeout, and Vite watching Cargo target

Environment

• Windows 11
• Node.js 24.16.0
• npm 11.13.0
• Rust 1.97.0
• Visual Studio Build Tools 2022
• FileExplorer 0.2.3, current main

Problem

A fresh Windows checkout could not be started with:

npm install
npm run tauri dev

I encountered three consecutive issues.

1. Tauri dialog plugin version mismatch

The initial run failed with:

Error Found version mismatched Tauri packages:
tauri-plugin-dialog (v2.0.0-rc) :
@tauri-apps/plugin-dialog (v2.7.1)

Updating the Rust dependency fixed it:

cargo add --manifest-path .\src-tauri\Cargo.toml tauri-plugin-dialog@2.7.1

Suggested change in src-tauri/Cargo.toml:

tauri-plugin-dialog = "2.7.1"

2. Tauri waits indefinitely for the Vite server on Windows

Vite reported:

Local: http://localhost:1420/

but Tauri repeatedly printed:

Waiting for your frontend dev server to start on http://localhost:1420/...

netstat showed that Vite was listening only on IPv6:

TCP [::1]:1420 LISTENING

while 127.0.0.1:1420 was unavailable.

The following changes fixed it:

In vite.config.js:

host: host || "127.0.0.1",

In src-tauri/tauri.conf.json:

"devUrl": "http://127.0.0.1:1420"

3. Vite watches the Cargo target directory

During Rust compilation, Vite terminated with:

Error: EBUSY: resource busy or locked, watch
'C:\Users\...\FileExplorer\target\debug\build\serde-...\build_script_build-....exe'

The existing Vite exclusion ignores only src-tauri, but Cargo places its target directory at the repository root in this setup.

Adding the Cargo target directory to the ignored paths fixed the problem:

watch: {
  ignored: ["**/src-tauri/**", "**/target/**"],
},

Additional Windows prerequisite

Because ssh2 enables vendored-openssl, the build also requires Perl:

configuring OpenSSL build: Command 'perl' not found

Installing Strawberry Perl resolved this. It may be useful to mention Perl in the Windows build prerequisites.

Result

After these changes and installing Perl, npm run tauri dev compiled successfully and launched the application.

Thank you, it's worked fine!
