Composer freezing when installing symfony vendors

问题

I'm trying to install Symfony 2. I get the same issue of I download the archive without vendors and if I try to install via curl.

Running OSX/MAMP setup.

As you can see below, if I do composer update I get a similar problem.

➜  composer update

Any suggestions on how to get past this? It works fine for me on an Ubuntu VM so I presume it is something to do with the setup.

回答1:

zlib extension enabled?

check your phpinfo if zlib ( which provides zlib_decode ) is enabled or run

php -m

if your php cli uses a different php.ini

cache problem?

[...] package information was loaded from the local cache and may be out of date

Delete composer's cache folder being...

 /Users/alexlongshaw/.composer/cache/

... in your case to prevent updating from cache only and see if a general connection exists.

proxy?

make sure you don't have a proxy set via environment-variables

https_proxy
http_proxy
HTTPS_PROXY
HTTP_PROXY

common problems

composer has built-in capabability of identifying some common problems

composer diagnose

回答2:

This turned out to be network related. Didn't work on either connection (Broadband or 3G) at home but at work there were no problems
