Composer (installing / updating) always fails

Question

I have a stable connection, however composer always throws Composer\\Downloader\\TransportException when I run composer update on my project root, followed by messages stating that I had a timeout error while downloading the files.

After running composer diagnose , everything seems to pass the test.

I attempted uninstalling, and, afterwards, I could not install composer. When I download composer with curl -sS https://getcomposer.org/installer | php curl -sS https://getcomposer.org/installer | php , composer prints this to the stream:

 ~  curl -sS https://getcomposer.org/installer | php -d detect_unicode=Off
All settings correct for using Composer

The download failed repeatedly, aborting.

I am using Ubuntu 14.04 LTS .

Any ideas on why this keeps happening?

Answer 1

I advised on this before. Try composer update/install -o -vvv and check wether the package is being loaded from composer's cache.

if yes try clearing composer's cache or try adding -cache-dir=/dev/null .

To force downloading an archive instead of cloning sources, use the --prefer-dist option in combination with --no-dev .

Otherwise you could try raising composer's process timeout value:

export COMPOSER_PROCESS_TIMEOUT=600 ( defaults to 300 )

I'm not sure that this applies to your reinstall option, but it might apply to your initial timeout problem (in addition to the suggestions of Vector); I was using hhvm to run composer , which specifies its own request timeout parameters, which override anything that you specify in your composer.json or the environment variables. The previous link contains the appropriate information to configure your timeout in more detail, but my example bash alias may help.

alias composer='hhvm -v ResourceLimit.SocketDefaultTimeout=60 -v Http.SlowQueryThreshold=60000 -v Eval.Jit=false /home/liam/bin/composer'
