Plugin not installing in IOS

[matthitachi]

ionic cordova plugin add cordova-plugin-firebase
npm install --save @ionic-native/firebase

not working, it just waits for a pretty long time and does not finally install.
i even created a new blank project and tried it but same problem.
Ran npm cache clean --force and updated my npm, still no change.
This is my environment information. Any help would be appreciated.

Error:
Failed to restore plugin "cordova-plugin-firebase" from config.xml. You might need to try adding it again. Error: Failed to fetch plugin cordova-plugin-firebase@^1.0.5 via registry.
Probably this is either a connection problem, or plugin spec is incorrect.
Check your connection and plugin name/version/URL.

Have you tried adding it through URL. Some people say that helps with some problems.

[ThonyFD]

Same issue, and I tried using the url, but doesn't work, some people say that the installation process finish ok after long time #760

[Flucadetena]

Have you tried to clone it and installed locally? Maybe an older version?

[matthitachi]

Try the
npm install --save @ionic-native/firebase
first before running
ionic cordova plugin add cordova-plugin-firebase

It worked for me.

install time will be fixed by #672
