确实％x []捕获所有输出？

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}=" 

我得到这样的结果

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svn_output内svn的错误消息。那可能吗？

你要标准错误重定向到标准输出：

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