Ruby on rails 使用Open3执行rake任务,ruby-on-rails,ruby,Ruby On Rails,Ruby,我试图在控制器内捕获rake任务的输出，如下所示： buffer = [] Open3.popen3("rake namespace:task") do |stdin, stdout, stderr| begin while line = stdout.readline buffer << line end rescue end end buffer=[] popen3（“rake名称空间：task”）do | stdin、stdout、st

我试图在控制器内捕获rake任务的输出，如下所示：

buffer = []
Open3.popen3("rake namespace:task") do |stdin, stdout, stderr|
  begin
    while line = stdout.readline
      buffer << line
    end
  rescue
  end
end

buffer=[]
popen3（“rake名称空间：task”）do | stdin、stdout、stderr|
开始
而line=stdout.readline

buffer将source
gems.gthub.com
添加到gem文件解决了我的问题。
