How to fix composer error "Content-Length Mismatch"

how_to.md

First, run:

$ composer config --list --global        //this will get the composer home path.
[home] /root/.composer                   //it's my composer home path.

And then, edit the config.json in [home] directory, make it like this:

{
  "config": {
    "github-protocols": [
      "https,ssh"
    ]
  },
  "repositories": {
    "packagist": {
      "type": "composer",
      "url": "https://packagist.org"
    }
  }
}

It will make the packagist connection force https. And also you could config the composer.json in your project, this is a laravel sample would be look like:

{
  "name": "laravel/laravel",
  "description": "The Laravel Framework.",
  "keywords": [
    "framework",
    "laravel"
  ],
  "license": "MIT",
  "type": "project",
  "require": {
    "php": ">=5.5.9",
    "laravel/framework": "5.2.*"
  },
  "config": {
    "preferred-install": "dist"
  },
  "repositories": {
    "packagist": {
      "type": "composer",
      "url": "https://packagist.org"
    }
  }
}

On Command, Just change the default repo url to:
composer config -g repo.packagist composer https://packagist.phpcomposer.com

Then It will be solved

@mr-sakr's solution worked for me, but I had to use the second aproach, putting it in my composer.json project file, something like that:

  "repositories": {
    "packagist": {
      "type": "composer",
      "url": "https://packagist.phpcomposer.com"
    }
  }

Content-Length mismatch, received 66937 bytes out of the expected 999743
http://repo.packagist.org could not be fully loaded, package information was loaded from the local cache and may be out of date

[Composer\Downloader\TransportException]
Content-Length mismatch, received 243335 bytes out of the expected 1700818

@mr-sakr thanks, its work!

composer config -g repo.packagist composer https://packagist.phpcomposer.com
.
Thanks. It worked for me

$ composer config -g repo.packagist composer https://packagist.org
$ composer config -g github-protocols https ssh

This does the same job :)

Thankyou @mr-sakr, working like a charm:

currently worked for me: https://packagist.phpcomposer.com

Awesome, this works for me

php -d memory_limit=-1 /usr/local/bin/composer require */*

thanks , that worked for me @mr-sakr

Brilliant. Thank you!

This works. Thanks a ton!

Nothing works for me. Trying to create a new yii project using composer. Anyone had the same problem with creating a new Yii2 framework project?

@whitesec-au in my case it was the following

"repositories": {
"packagist": {
"type": "composer",
"url": "https://packagist.org"
}
}

I had "https://asset-packagist.org" instead of just "https://packagist.org". I changed that and it worked

$ composer config -g repo.packagist composer https://packagist.org
$ composer config -g github-protocols https ssh

This does the same job :)

Thank you this worked for me

$ composer config -g repo.packagist composer https://packagist.org
$ composer config -g github-protocols https ssh

This does the same job :)

This resolved the issue for me

Still getting a content-length mismatch error even after trying the above mentioned solutions. This happens when I'm trying to create a new laravel project.
