jython报错，亲测有效Exception in thread “main“ ImportError: Cannot import site module and its dependencies:

在idea中使用jython时出现以下错误

**

Exception in thread “main” ImportError: Cannot import site module and its dependencies: No module named site

**
Determine if the following attributes are correct:

• sys.path: [‘D:\maven\maven-repository\org\python\jython\2.7.0\Lib’, ‘classpath’, ‘pyclasspath/’]
  This attribute might be including the wrong directories, such as from CPython
• sys.prefix: D:\maven\maven-repository\org\python\jython\2.7.0
  This attribute is set by the system property python.home, although it can
  be often automatically determined by the location of the Jython jar file

You can use the -S option or python.import.site=false to not import the site module

主要两个解决方法，第一个在代码前面加上

        Properties props = new Properties();
        props.put("python.home", "path to the Lib folder");
        props.put("python.console.encoding", "UTF-8");
        props.put("python.security.respectJavaAccessibility", "false");
        props.put("python.import.site", "false");
        Properties preprops = System.getProperties();
        PythonInterpreter.initialize(preprops, props, new String[0]);

第二个方法，在pom.xml中加入jython-standalone的依赖

        <dependency>
            <groupId>org.python</groupId>
            <artifactId>jython-standalone</artifactId>
            <version>2.7.1</version>
        </dependency>
