Composer Content-Length Mismatch

Question

Sometimes when I run composer update to upgrade the laravel project, a content-length mismatch exception might occur. Finally, I get this is because of the terrible firewall in China: the DNS was poisoned. So, if you are like me, could there be a way to fix it out?

Answer 1

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, make it like this:

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

Update

Before Composer v1.2.3 the repository key for packagist was "packagist". In v1.2.3 it was changed to "packagist.org" (see commit e38ebef).
