我是jython的新手。这是我尝试使用javac将我的python脚本编译成类文件的失败尝试。
rohit@rohit-laptop:~/backyard$ echo "print 'hi'" > test.py
rohit@rohit-laptop:~/backyard$ jython test.py
hi
rohit@rohit-laptop:~/backyard$ jythonc test.py

请建议正确的方法。

Jython会在第一次执行时自动将其编译成.class文件，但是如果你想编译它，可以使用标准库，在Jython lib文件夹中找到py_compile.py或compileall.py。

$ java test # is not the exact command to execute the class file
此类文件需要执行jython.jar文件，您必须在运行时提供jython.jar路径。
#java -cp /home/litindia/jython-2.0.1/jython.jar:. test
-cp是强制性的/home/litindia/jython-2.0.1/jython.jar是我的路径jython.jar出现在我的系统中，您的路径可能会有所不同。所以请给出适当的路径。
路径:.是强制性的。然后需要文件名。
