Ionic-cli: Error: Failed to fetch plugin from a URL

Created on 7 Sep 2017  路  34Comments  路  Source: ionic-team/ionic-cli

Description:
ionic cordova plugin add {URL} fails.
I tried to add the WKWebView as an example on a brand new ionic app, and it failed.
ionic cordova plugin add https://github.com/ionic-team/cordova-plugin-wkwebview-engine.git --save

However, if I run the command without the "ionic" (i.e. using Cordova) it works fine. However, when packaging in the Ionic Cloud, it doesn't seem to work.

cordova plugin add https://github.com/ionic-team/cordova-plugin-wkwebview-engine.git --save

Steps to Reproduce:
Create a new Ionic Blank App
Run: ionic cordova plugin add https://github.com/ionic-team/cordova-plugin-wkwebview-engine.git --save

Output:
C:\mobile\TestApp>ionic cordova plugin add https://github.com/ionic-team/cordova-plugin-wkwebview-engine.git --save

cordova plugin add https://github.com/ionic-team/cordova-plugin-wkwebview-engine.git --save
脳 Running command - failed!
[ERROR] An error occurred while running cordova plugin add

    Probably this is either a connection problem, or plugin spec is incorrect.

replace git+https with https in both config.xml and package.json

Looks like this is your issue: fatal: Unable to find remote helper for 'https'

Try updating git on your machine.

I had git version 2.13.1 on Windows
I updated to the latest git 2.14.1 now I get a different error.

How come running the same command directly using cordova command, works fine??

Also, the original issue is happening on 2 different computers.

I'm not sure yet. What's the new error?

How did you install git? It seems to have issues.
What shell are you using?
What's the output of: git --exec-path ?

imhoffd picture imhoffd on 8 Sep 2017

I just went to the Git web site and downloaded the Git windows installer and installed it
the output of: git --exec-path:
C:\Program Files\Git\mingw64/libexec/git-core

I think it is the vqariable (-q) should be (--quiet)

neoassyrian picture neoassyrian on 8 Sep 2017

What about npm install https://github.com/ionic-team/cordova-plugin-wkwebview-engine.git --save ?

imhoffd picture imhoffd on 8 Sep 2017

That seems to work fine.
No issues.

neoassyrian picture neoassyrian on 8 Sep 2017

Is there going to be a fix for this?

neoassyrian picture neoassyrian on 12 Sep 2017

@neoassyrian I would just use the Cordova CLI directly. I may start recommending people do this normally. The ionic cordova platform and ionic cordova plugin commands offer little benefit over cordova platform and cordova plugin. We just added them to fully wrap it.

This is not working in the cloud either when running "ionic package build" command. Getting the original error.

The same for me

same,using npm or cordova to install is ok,but using ionic is error

coloz picture coloz on 12 Nov 2017

Inline with what @kleeb mentioned, changing the following path prefixes in config.xml && package.json seems to have alleviated the issue in a permanent manner.

git+https://... -> https://...
git+ssh://... -> ssh://...

@dwieeb 's suggestion worked for me straightaway.
just use the Cordova CLI directly wihtout ionic wrapper:

cordova plugin add https://github.com/ionic-team/cordova-plugin-wkwebview-engine

@maikosoft @L96Github @zmoshansky @coloz @pvdyck @kleeb May I ask if you are using Windows with Command Prompt or Git Bash?

imhoffd picture imhoffd on 13 Jul 2018

MacOS, zsh, git; Team-mates also experienced similar on MacOS, bash? (default iterm2), git.

zmoshansky picture zmoshansky on 13 Jul 2018

@zmoshansky Okay, I use the same. Can I see all the <plugin elements in your config.xml? On my computer it added the plugin successfully with this command:

ionic cordova plugin add https://github.com/ionic-team/cordova-plugin-wkwebview-engine.git

Installs the plugin and puts this in my config.xml: 

    <plugin name="cordova-plugin-wkwebview-engine" spec="https://github.com/ionic-team/cordova-plugin-wkwebview-engine.git" />

@dwieeb gitbash

maikosoft picture maikosoft on 13 Jul 2018

@dwieeb, I can share the following:

This is a fork of a plugin that we use,
ionic cordova plugin add git+https://github.com/flipflopapp/cordova-universal-links-plugin fails
ionic cordova plugin add https://github.com/flipflopapp/cordova-universal-links-plugin succeeds.

We have one other forked plugin that also has the same issue; In both cases, I've noticed the package.json contains the original repo url, instead of the forked repo url. Is it possible the git+ prefix causes the package.json to be checked and errors when the url's don't align or elicits this error?

I would intuitive expect that prefixed or not, those commands should behave consistently.
(IIRC, some tooling causes these to have git+ prefix re-added constantly, thus the battle back and forth).

zmoshansky picture zmoshansky on 30 Jul 2018

For me, those commands save the correct forked URL to config.xml and package.json.

git+ prefix:

ionic cordova plugin add git+https://github.com/flipflopapp/cordova-universal-links-plugin 

    <plugin name="cordova-universal-links-plugin" spec="git+https://github.com/flipflopapp/cordova-universal-links-plugin.git" />

    "cordova-universal-links-plugin": "git+https://github.com/flipflopapp/cordova-universal-links-plugin.git",

no git+ prefix:

ionic cordova plugin add https://github.com/flipflopapp/cordova-universal-links-plugin 

    <plugin name="cordova-universal-links-plugin" spec="https://github.com/flipflopapp/cordova-universal-links-plugin.git" />

    "cordova-universal-links-plugin": "git+https://github.com/flipflopapp/cordova-universal-links-plugin.git",

I think Cordova/npm always adds the git+ prefix to package.json because just the URL isn't a valid URL according to the package.json spec: https://docs.npmjs.com/files/package.json#git-urls-as-dependencies

imhoffd picture imhoffd on 31 Jul 2018

@dwieeb I'm suspect of this perhaps stemming from npm 3 / node 5 in my case, vs npm 5 and node 8 on yours. Unfortunately we still have some deps to upgrade before we can move to node 8/npm 5.

zmoshansky picture zmoshansky on 31 Jul 2018

I've tested node 6 + npm 3 before. I just did again, and got the same behavior as before.

I thought originally it was an issue with the git version. But I'm stumped as to why it works for Cordova CLI, but not when Ionic CLI wraps the exact same command.

imhoffd picture imhoffd on 31 Jul 2018

This command fixed it for me:
git config --global url."https://".insteadOf git+https://

steenstra picture steenstra on 18 Mar 2020

I spent hours on this. Downgrading from Cordova 10.0.0 to 9.0.0 ([email protected]) worked for me
