情感分析无法连接LM（Loughran and McDonald）词典，即ps.LM()

Question

https://github.com/hanzhichao2000/pysentiment是我试图为我工作的代码，因为我想评估一段文本是正的还是负的。在

我真的不明白为什么它不起作用，如果有人能给我任何建议，我会很高兴的。（这可能与我在学校电脑上运行这一点有关，我需要它在那里工作，也就是说，到python（2.7）的路径不像通常那样简单，因此我下载文件夹，而不是做pip安装或类似操作，并将它们添加到Lib文件夹中）

我把整个错误代码放在下面，因为我不知道什么是最相关的。谢谢您！在
