linux - Chef Recipe - 用 sed 命令替换 Linux 文件中的文本(接收错误)

Question

我在 Chef Recipe 中使用了以下代码:

bash 'replace_text' do
    cwd ::File.dirname('/data01/nodemanager/bin')
    code <<-EOH
      sed 's/NODEMGR_HOME=.*/NODEMGR_HOME="\/data01\/nodemanager"/g' startNodeManager.sh
      EOH
  end

我要替换的文本是包含 NODEMGR_HOME= startNodeManager.sh 的行中的所有内容，位于 /data01/nodemanager/bin

并且我在运行 Recipe 时收到以下输出:

您的反斜杠转义级别不够。请记住，它首先是一个 Ruby 字符串，然后是一个 bash 字符串，然后是一个 sed 参数。您也可以使用 line 或 poise-file 说明书来回避整个问题。
