Composer update error

gistfile1.txt

When running any composer commands, sometimes you see the following error stack:

```
                                                                          
  [ReflectionException]                                                   
  Class Fxp\Composer\AssetPlugin\Repository\NpmRepository does not exist  
                                                                          

                                                                                                    
  [ErrorException]                                                                                  
  Declaration of Fxp\Composer\AssetPlugin\Repository\AbstractAssetsRepository::whatProvides() shou  
  ld be compatible with Composer\Repository\ComposerRepository::whatProvides(Composer\DependencyRe  
  solver\Pool $pool, $name, $bypassFilters = false) 
  
```

To correct this, you need to install/update **fxp/composer-asset-plugin** plugin. You can do that by running the following commands:

```
composer global require fxp/composer-asset-plugin --no-plugins // For installing it first time
composer global update fxp/composer-asset-plugin --no-plugins // For updating plugin, if already installed

```

Thank you, very helpful

Helped me! Thank you!

I have done all of these, but still I had the same problem. I removed vendor/fxp and it fixed.

I have been trying all kind of solutions and the only way I was able to fix it was following the steps mentioned here.
