我正在尝试在 deploy.rb
中添加配置参数,以便正确构建 pg
gem:
before "bundle:install" do
run "ls -l #{fetch(:latest_release)}/Gemfile"
run "bundle config --local --gemfile=#{fetch(:latest_release)}/Gemfile build.pg --with-pg-config=/usr/pgsql-9.1/bin/pg_config"
end
在输出中,添加的诊断代码清楚地显示了非空 Gemfile 的存在:
* executing `bundle:install'
triggering before callbacks for `bundle:install'
* executing "ls -l /apps/my_app/releases/20121008195429/Gemfile"
servers: ["my_server.com"]
[my_server.com] executing command
** [out :: my_server.com] -rw-r--r-- 1 webapp webapp 1291 Oct 5 22:34 /apps/my_app/releases/20121008195429/Gemfile
command finished in 157ms
* executing "bundle config --local --gemfile=/apps/my_app/releases/20121008195429/Gemfile build.pg --with-pg-config=/usr/pgsql-9.1/bin/pg_config"
servers: ["my_server.com"]
[my_server.com] executing command
** [out :: my_server.com] Could not locate Gemfile
如果我使用 --global
代替 --local
,我会得到相同的结果。如果我删除 global
/local
标志,我会得到一个不同的错误:
** [out :: my_server.com] Invalid scope --gemfile=/apps/my_app/releases/20121008194937/Gemfile given. Please use --local or --global.
似乎有一个全局配置或上下文使情况变得困惑。如何让 bundle config
看到我的 Gemfile
?有更好的方法吗?
最佳答案
与 bundle install
命令中使用的 --gemfile
标志相比,bundle config
中的标志仅标识 Gemfile 的名称:
# man bundle-config
...
gemfile (BUNDLE_GEMFILE)
The name of the file that bundler should use as the Gemfile. This location of this file
also sets the root of the project, which is used to resolve relative paths in the Gemfile,
among other things. By default, bundler will search up from the current working directory
until it finds a Gemfile.
我先通过 cd 到该目录解决了这个问题:
run "cd #{fetch(:latest_release)} && bundle config build.pg --with-pg-config=/usr/pgsql-9.1/bin/pg_config"
