【问题描述】：

我想使用 shell 命令从 java 执行 python 脚本文件位置：d:/python/test.py

下面是我的java程序

def callstme(){
        Process p
        try {

            List<String> cmdList = new ArrayList<String>();
            cmdList.add("sh");
            cmdList.add("d:/python/test.py");
            ProcessBuilder pb = new ProcessBuilder(cmdList);
            p = pb.start();

            p.waitFor();
            BufferedReader reader=new BufferedReader(new InputStreamReader(
             p.getInputStream()));
            String line;
            while((line = reader.readLine()) != null) {
                System.out.println(line);
            }
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (InterruptedException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }

执行时出现错误

"java.io.IOException: Cannot run program "sh": CreateProcess error=2, The system cannot find the file specified
    at java.lang.ProcessBuilder.start(ProcessBuilder.java:1048)
