PHP Fatal error: Class 'Icecave\Isolator\Isolator' not found in eloquent/composer-npm-bridge/src/NpmClient.php on line 35

I am trying to use the bridge in my Symfony2-project (2.7.8).
When I add "eloquent/composer-npm-bridge":"~3.0" to my require section an call composer.phar update, I get the following error:

It works with "eloquent/composer-npm-bridge":"~2.1"

[ezzatron]

Thanks for the report, I'll look into it.

@jmalloc, this looks related to the issue you were having?

[nwoetzel]

Could source of that problem be the changes in composer.json
"icecave/isolator": "~2" in version 2.1 to
"icecave/isolator": "^2|^3" in version 3.0.0
but icecave/isolator in version 3 does not have a Class 'Icecave\Isolator\Isolator' but instead an IsolatorAbstract class? I am not sure what has changed - and if it can just be changed to that, but it is clear, that "icecave/isolator": "^2|^3" is not compatible - only ^2

[ezzatron]

Isolator 3 uses an autoloader to generate Icecave\Isolator\Isolator at run time. It seems what was happening is that the autoload mechanism used by Isolator 3 was not available at the time the plugin ran. In addition, once the isolator is generated, it is cached on disk, so that's probably how I missed this issue.

In any case, it's probably better that this plugin doesn't require any dependencies, so I simply re-wrote the portion of the code that used Isolator to function without it.

Can you please try your use-case with "eloquent/composer-npm-bridge": "dev-develop"?

[nwoetzel]

This is the new error I get with "eloquent/composer-npm-bridge": "dev-develop"

[nwoetzel]

second call to composer.phar update works without an error

[nwoetzel]

So I had 2.1 installed, changed to dev-devlop and called composer.phar update and that was the output:
You are running composer with xdebug enabled. This has a major impact on runtime performance. See https://getcomposer.org/xdebug
The "eloquent/composer-npm-bridge" plugin requires composer-plugin-api 1.0.0, this WILL break in the future and it should be fixed ASAP (require ^1.0 for example).

calling composer.phar update again works just fine and updates npm dependencies

[nwoetzel]

I will try to remove the "eloquent/composer-npm-bridge": "dev-develop" - update - and add it back again
I should be able to see if this was just an artifact of the 2.1 installation

[nwoetzel]

when I remove and call composer update I get this output

This might be realted to #5 and could be the same error as observed there

When adding "eloquent/composer-npm-bridge": "dev-develop" back in it works as expected:

Thanks a lot for the quick fix. Looking forward to the actual release!

Yeah, from memory, Composer does some weird thing where it tries to run the old version of a plugin, even when updating the plugin itself. This explains the "works on second run" you're seeing. I'm not aware of any way to "fix" the issue. From a quick search, this looks to be related: composer/issues#4520.

So long as it works when you do something like the following:

• delete vendor (and composer.lock for good measure)
• update composer-npm-bridge dependency
• composer update

Then I consider it to be "working".

I'll probably add something to the readme about this at some point.

[ezzatron]

Fixed in 3.0.1.
