Theia cannot be started properly without LocalHost binding

[bjzhangtao]

Bug Description:

Theia cannot be started properly without LocalHost binding，I bound localhost to 127.0.0.1 and it started normally，but the user can't be required to bind, How to Get Rid of Dependencies

Steps to Reproduce:

native node modules are already rebuilt for electron
$ electron scripts/theia-electron-main.js

root INFO Backend MiniBrowserEndpoint.configure: 0.6 ms [Finished 1.702 s after backend start]
root ERROR Uncaught Exception:  Error: getaddrinfo ENOTFOUND localhost
root ERROR Error: getaddrinfo ENOTFOUND localhost
    at GetAddrInfoReqWrap.onlookup [as oncomplete] (node:dns:71:26)
root WARN The local plugin referenced by local-dir:/Users/hostname/.theia/plugins does not exist.

Additional Information

• Operating System: macOS Monterey ：12.5 MacBook Pro (16-inch, 2019)
• Theia Version: "@theia/cli": "1.23.0"

This is the first time I hear about the localhost host not being defined, how did that happen?

Official Git Repository，application with Electron

• yangster-electron （or use dmg）
• theia.git

localhost not being a valid host on your system should be independent from those applications/repositories, I would be more interested with how you ended up in that state with your system?

Actually we develop an application based on Theia. Some users gave us feedback that the applicaiton could not be started without localhost defined. We are seeking for an solution to support starting Theia without localhost defined in user's platform. Appreciate any help you provide. Thanks!

Moved from #11930:

We have received reports of non-functional Theia electron apps from multiple users:

• arduino/arduino-ide#1708
• arduino/arduino-ide#1527

Our users were friendly to help us, and they could reproduce the bug with the TheiaBlueprint application.
