%x []捕获所有输出吗？

Question

如果我运行此代码:

svn_output = %x[svn update /Users/radek/Sites/db2.rft -r 11105 --force ]
puts
puts " output is  =#{svn_output}="

我得到了这个结果

svn: Working copy '/Users/radek/Sites/db2.rft' locked
svn: run 'svn cleanup' to remove locks (type 'svn help cleanup' for details)

 output is  ==

但我想从变量中的svn发出错误消息svn_output.那可能吗？

Answer 1

您想将stderr重定向到stdout:

svn_output = %x[svn update /Users/radek/Sites/db2.rft -r 11105 --force 2>&1]
puts
puts " output is  =#{svn_output}="
