Running python file in cmd through java- %1 is not a valid Win32 application(1个答案)
4个月前关闭。
我正在尝试用java程序执行一个python文件(test1.py)。
下面是我们的代码:
import java.io.*;
import java.nio.charset.StandardCharsets;
public class pro {
public Process mProcess;
public pro() {
Process process;
try {
process = Runtime.getRuntime().exec("test1.py");
mProcess = process;
} catch (Exception e) {
System.out.println("Exception Raised" + e.toString());
}
InputStream stdout = (mProcess != null) ? mProcess.getInputStream(): null;
BufferedReader reader = new BufferedReader(new InputStreamReader(stdout, StandardCharsets.UTF_8));
String line;
try {
while ((line = reader.readLine()) != null) {
System.out.println("stdout: " + line);
}
} catch (IOException e) {
System.out.println("Exception in reading output" + e.toString());
}
}
}
线process = Runtime.getRuntime().exec(new String[] { "test1.py"});
抛出Exception Raisedjava.io.IOException: Cannot run program "test1.py": CreateProcess error=193, %1 is not a valid Win32 application
怎么啦?

我觉得唯一的问题是在这条线上
test1.py 只是一个python文件,您需要像在shell或命令提示符中那样告诉exec如何运行此文件
