46
The [plugin:install|INFO] task installs a plugin:
47
 
48
  [./symfony plugin:install sfGuardPlugin|INFO]
49
 
50
By default, it installs the latest [stable|COMMENT] release.
51
 
52
If you want to install a plugin that is not stable yet,
53
use the [stability|COMMENT] option:
54
 
55
  [./symfony plugin:install --stability=beta sfGuardPlugin|INFO]
56
  [./symfony plugin:install -s beta sfGuardPlugin|INFO]
57
 
58
You can also force the installation of a specific version:
59
 
60
  [./symfony plugin:install --release=1.0.0 sfGuardPlugin|INFO]
61
  [./symfony plugin:install -r 1.0.0 sfGuardPlugin|INFO]
62
 
63
To force installation of all required dependencies, use the [install_deps|INFO] flag:
64
 
65
  [./symfony plugin:install --install-deps sfGuardPlugin|INFO]
66
  [./symfony plugin:install -d sfGuardPlugin|INFO]
67
 
68
By default, the PEAR channel used is [symfony-plugins|INFO]
69
(plugins.symfony-project.org).
70
 
71
You can specify another channel with the [channel|COMMENT] option:
72
 
73
  [./symfony plugin:install --channel=mypearchannel sfGuardPlugin|INFO]
74
  [./symfony plugin:install -c mypearchannel sfGuardPlugin|INFO]
75
 
76
You can also install PEAR packages hosted on a website:
77
 
78
  [./symfony plugin:install http://somewhere.example.com/sfGuardPlugin-1.0.0.tgz|INFO]
79
 
80
Or local PEAR packages:
81
 
82
  [./symfony plugin:install /home/fabien/plugins/sfGuardPlugin-1.0.0.tgz|INFO]
83
 
84
If the plugin contains some web content (images, stylesheets or javascripts),
85
the task creates a [%name%|COMMENT] symbolic link for those assets under [web/|COMMENT].
86
On Windows, the task copy all the files to the [web/%name%|COMMENT] directory.
