我有一个奇怪的用例,我需要从另一个新建的Rails应用程序上的Rails应用程序上发出“bundle install”(作为system()命令),而不需要Gemfile.lock
我知道这通常是从命令行完成的,但我需要在Rails中完成。
作为参考,irb可以轻松实现这一点。它按预期基于Gemfile获取gem,并生成Gemfile.lock。
出于某种原因,当我在Rails控制台(来自另一个应用程序)并且我发出相同系列的命令时,bundle命令实际上不会获取或更新gem并且不会生成Gemfile.lock。
正如塔德曼指出的那样,我认为这是由于irb
和rails console
之间环境的变化。从system()执行时,bundle install
命令作用于启动Rails控制台而不是目标应用程序的Rails应用程序。
即使尝试将Rails控制台中的ENV
变量与irb
中的变量匹配,我仍然无法弄清楚(参见下面的尝试)。
测试此步骤的步骤:
cd && rails new myapp --skip-bundle
rails console
Dir.chdir("/home/user/myapp")
system("bundle install")
使用 irb (成功):
1.9.3p429 :002 > Dir.chdir("/home/user/myapp")
=> 0
1.9.3p429 :003 > system("bundle install")

编辑1:在tadman的考虑之后,我尝试过这会抛出一个奇怪的包错误:
[6] pry(main)> system({"BUNDLE_GEMFILE" => nil}, "bundle install")
git://github.com/plataformatec/devise.git (at rails4) is not checked out. Please run `bundle install`
和
[6] pry(main)> system({"BUNDLE_GEMFILE" => "/home/user/myapp/Gemfile"}, "bundle install")
git://github.com/plataformatec/devise.git (at rails4) is not checked out. Please run `bundle install`
谢谢!
答案 0 :(得分:8)
解决:
Bundler.with_clean_env { Dir.chdir("/path/to/myapp") { `bundle install` } }
对于#bundler,所有功劳归于#bundler上的irc用户间接。
答案 1 :(得分:0)
在我的案例中使用Bundler.with_clean_env {Dir.chdir" / path / to / myapp" {bundle install
}}
请注意相同但没有"("和")"
