CLI: `'yarn' is not recognized as ...` message for operations on Windows

[FLGMwt]

Description

Bug:

The packager check on Windows, in contrast to the same check on non-Windows platforms, does not mute error output. Consequently, the following message is output when running yarn --version:

'yarn' is not recognized as an internal or external command,
operable program or batch file.

Since npm is a legitimate and supported fallback, I believe this adds noise to the output and, more concerningly, confusion for developers not aware of yarn.

Expected behavior

In the absence of yarn on Windows, react-vr should not report a yarn error.

Actual behavior

The following message appears on all react-vr-cli output on Windows:

'yarn' is not recognized as an internal or external command,
operable program or batch file.

Reproduction

On a Windows system, without the yarn packager installed or available on the current path, run react-vr with no parameters. You should see the "'yarn' is not recognized" error.

Solution

Mute output for the yarn check on Windows: yarn --version 2> NUL (PR coming up shortly)

Additional Information

• React VR version: react-vr-cli: "3.3.0"
• Operating System: Windows 10
• Graphics Card: N/A
• Browser: N/A
• VR Device: N/A
