[英]How to get bundle_path from rbenv setting in Capistrano deploy.rb?
Since I have require capistrano-bundler
and capistrano-rbenv
gems, and have set as follow in deploy.rb file:由于我需要
capistrano-bundler
和capistrano-rbenv
gems,并且在 deploy.rb 文件中设置如下:
# rbenv
set :rbenv_type, :user
set :rbenv_ruby, '2.0.0-p645'
set :rbenv_prefix, "RBENV_ROOT=#{fetch(:rbenv_path)} RBENV_VERSION=#{fetch(:rbenv_ruby)} #{fetch(:rbenv_path)}/bin/rbenv exec"
set :rbenv_map_bins, %w{rake gem bundle ruby rails}
# bundler
set :bundle_roles, :all # this is default
set :bundle_servers, -> { release_roles(fetch(:bundle_roles)) } # this is default
set :bundle_binstubs, -> { shared_path.join('bin') } # default: nil
set :bundle_gemfile, -> { release_path.join('Gemfile') } # default: nil
set :bundle_path, -> { shared_path.join('bundle') } # this is default
set :bundle_without, %w{development test}.join(' ') # this is default
set :bundle_flags, '--deployment --quiet' # this is default
set :bundle_env_variables, {} # this is default
Clearly bundle_path is not in shared
subpath, it should be /home/deploy/.rbenv/shims/bundle
.显然 bundle_path 不在
shared
子路径中,它应该是/home/deploy/.rbenv/shims/bundle
。 So how can I get that path after I have set rbenv's settings.那么在我设置了 rbenv 的设置后,我如何才能获得该路径。 I struggle for a long time but found nothing both on github or
google.com
.我挣扎了很长时间,但在github或
google.com
上一无所获。
Thx.谢谢。
To get rbenv's gem path you can do rbenv exec gem environment gemdir
.要获得 rbenv 的 gem 路径,您可以执行
rbenv exec gem environment gemdir
。
However, I think the problem comes from the combination of the :bundle_path
, :bundle_flags
settings, and how bundler interacts with rbenv.但是,我认为问题来自
:bundle_path
、 :bundle_flags
设置的组合,以及 bundler 如何与 rbenv 交互。
Because of the --deployment
option (set in :bundle_flags
), the installed gems won't install their binaries in rbenv's system gemdir, but on app/shared/bundle
, so you won't get them in your $PATH
.由于的
--deployment
选项(在设置:bundle_flags
),安装的宝石不会rbenv的系统gemdir安装它们的可执行文件,但在app/shared/bundle
,这样你就不会在你得到他们$PATH
。
To fix this, you need to add your command to both :rbenv_map_bins
and :bundle_bins
so that it is properly prefixed.要解决此问题,您需要将命令添加到
:rbenv_map_bins
和:bundle_bins
以便正确添加前缀。
For example, for jekyll, you need to set:比如对于jekyll,需要设置:
set :rbenv_map_bins, fetch(:rbenv_map_bins, []).push('jekyll')
set :bundle_bins, fetch(:bundle_bins, []).push('jekyll')
This makes the command executed by capistrano to be something like这使得由 capistrano 执行的命令类似于
RBENV_ROOT=#{fetch(:rbenv_path)} RBENV_VERSION=#{fetch(:rbenv_ruby)} #{fetch(:rbenv_path)}/bin/rbenv exec bundle exec jekyll
which will work because bundle
is in :rbenv_map_bins
and bundle install --deployment
creates a .bundler/config
file that sets the path to app/share/bundle
这将起作用,因为
bundle
在:rbenv_map_bins
并且bundle install --deployment
.bundler/config
创建了一个.bundler/config
文件,该文件设置了app/share/bundle
的路径
