请帮帮我

您的ruby版本太旧，无法运行

get\u进程\u mem

gem。gem使用解析来自linux服务器上的

/proc

文件的信息。然而，Ruby1.8.7还不支持这样复杂的regexp

你可以在irb中看到自己。在ruby 1.8.7中，匹配失败：

"aaa" =~ /(?<value>(\d*\.{0,1}\d+))\s+(?<unit>\w\w)/
# => SyntaxError: compile error
# => (irb):1: undefined (?...) sequence: /(?<value>(\d*\.{0,1}\d+))\s+(?<unit>\w\w)/

“aaa”=~/（？（\d*\.{0,1}\d+）\s+（？\w\w）/
#=>语法错误：编译错误
#=>（irb）：1：未定义的（？…）序列：/（？（\d*\.{0,1}\d+）\s+（？\w\w）/

而在ruby 2.2下，它工作正常（在这个测试用例中不会返回任何内容，但更重要的是，不会出现错误）：

“aaa”=~/（？（\d*\.{0,1}\d+）\s+（？\w\w）/
#=>零

您现在有几个选择：

如果可以，升级到更新的ruby（和rails），您将不必解决这些与旧代码相关的问题，也不再使用不受支持的ruby/rails版本，但这是一个相当麻烦的过程
摆脱
```
Get\u进程\u mem
```
gem。您可以使用命令行实用程序查看相同的信息，即进程消耗的内存，而无需安装任何gem例如，尝试
top
或
htop
命令。
