How Do We Reproduce?

Try installing on Windows 10

Extra (like a sample repo to reproduce the issue, etc.)

The problem is "wget" command which is not avaliable on windows sistem. Instead we can use de command "curl" with -o and -L option.

After some researches I figured out that the command function executes the script inserted as parameter in cmd.exe in windows systems ( maybe I'm wrong ).

I tried to execute the curl command with -O and -L parameters, as mentioned before, but I got a couple of errors.
So I modified the parameters suplied to curl to avoid also The revocation function was unable to check revocation for the certificate error with curl -O "http://simple-test" --ssl-no-revok and everything went right.

Finally the modified code in "scripts/setup-offline/run-setup-tts.js" should be:

import`` fs from 'node:fs'

import { command } from 'execa'

import { LogHelper } from '@/helpers/log-helper'
import { SystemHelper } from '@/helpers/system-helper'

  new Promise(async (resolve, reject) => {

    const destFliteFolder = 'bin/flite'
    const tmpDir = 'scripts/tmp'
    let makeCores = ''
    if (SystemHelper.getNumberOfCPUCores() > 2) {
      makeCores = `-j ${SystemHelper.getNumberOfCPUCores() - 2}`
    }
    let downloader = 'wget'
    if (SystemHelper.getInformation().type === 'macos') {
      downloader = 'curl -L -O'
    } else if (SystemHelper.getInformation().type === 'windows') { // this is the added block for windows curl command
        downloader = 'curl -O --ssl-no-revok'
    }


    if (!fs.existsSync(`${destFliteFolder}/flite`)) {

After replacing scripts/setup-offline/run-setup-tts.js with the above code, I now get this error:

Evidently the Windows TTS script also needs a rewrite, as I get:

c:\Users\User1\.leon>npm run setup:offline-stt

...so the same wget problem.

curl check revocation error on stackoverflow: https://stackoverflow.com/questions/54938026/curl-unknown-error-0x80092012-the-revocation-function-was-unable-to-check-r

One thing I'm fairly sure is wrong is that there shouldn't be the two ''s after the first 'import' in the script. I removed those and tried again. This time I get:

c:\Users\User1.leon\scripts\setup-offline>npm run setup:offline-tts

[email protected] setup:offline-tts
ts-node scripts/setup-offline/run-setup-tts.js

and that's it. When I try to do

leon start

again I still get:

.: TTS :.
ℹ️ Initializing TTS...

.: FLITE TTS SYNTHESIZER :.
✅ New instance
🚨 Cannot find bin\flite\flite You can set up the offline TTS by running: "npm run setup:offline-tts"

[thebitmaster]

I then went back to another doc page here:

https://docs.getleon.ai/1.0.0-beta.4/offline

And so I ran:

[email protected] setup:offline
ts-node scripts/setup-offline/setup-offline.js

ℹ️ Checking OS environment...
🚨 Voice offline mode is not available on Windows
🚨 undefined

c:\Users\User1.leon\scripts\setup-offline>

So is it actually not supported yet?

Thanks for all your hard work on Leon!
