我的桌面上有一个我想运行的程序(url 中的结构),但是当我编译时,
\code\nlp\assignments\parsing\javac PCFGParserTester.java
我得到:
PCFGParserTester.java:6: error: package nlp.io does not exist
import nlp.io.PennTreebankReader;
^
PCFGParserTester.java:7: error: package nlp.ling does not exist
import nlp.ling.Tree;
^
PCFGParserTester.java:8: error: package nlp.ling does not exist
import nlp.ling.Trees;
^
PCFGParserTester.java:9: error: package nlp.parser does not exist
import nlp.parser.EnglishPennTreebankParseEvaluator;
如何让我的程序正确导入我的包?
