無法找到Jython類

我寫了一個名爲jug.java的java文件，它使用jython和PythonInterpreter;這是代碼：無法找到Jython類

import org.python.util.PythonInterpreter; 
import org.python.core.PyObject; 

public class Jug{ 
    public void main(String[] args) { 
     PythonInterpreter interpreter = new PythonInterpreter(); 
     interpreter.exec("import InstaFeed\nAPI=InstaFeed.InstaFeed(someusername, somepassword)"); 
     PyObject someFunc = interpreter.get("API.like(mediaId"); 
     PyObject result = someFunc.__call__(new PyInteger(15)); 
     String realResult = (String) result.__tojava__(String.class); 
    } 
}

當我嘗試使用這個命令執行它：

javac Jug.java

這些錯誤發生：

Jug.java:1: error: package org.python.util does not exist 
import org.python.util.PythonInterpreter; 
        ^
Jug.java:2: error: package org.python.core does not exist

     PyObject someFunc = interpreter.get("like"); 
     ^

    location: class Jug 
Jug.java:9: error: cannot find symbol 
     PyObject result = someFunc.__call__(new PyInteger(15)); 
     ^

    location: class Jug

     PyObject result = someFunc.__call__(new PyInteger(15)); 
               ^
    symbol: class PyInteger 
    location: class Jug 
7 errors

而且安裝的Jython。我該如何解決這個錯誤？

更多信息

已經我已經安裝了Jython的使用終端：

sudo apt install jython

它成功地安裝Jython的。但每當我嘗試從源安裝：

sudo java -jar jython-installer-2.7.0.jar

這些錯誤發生：

包org.python.util應在jython.jar存在你缺少

你可以從jython下載

如果存在將它添加到您的命令（而不是javac Jug.java）

java -cp jython.jar:. Jug

我無法從源碼安裝，請閱讀我剛添加的信息。 –

您是否嘗試過調用java -cp jython-installer-2.7.0.jar :.壺？ – user7294900

是和輸出：錯誤：無法找到或加載主類Jug –
