无法在R中安装pattern.nlp包

Question

我试图在R中安装pattern.nlp包，但有几个错误正在经历。这个软件包用于python库，所以我改变了环境变量的路径。但在运行下面的代码时，我收到错误。

$ 

x <- pattern_sentiment("i really really hate iphones", language = "english") 



Error in data.table::setDF(score) : 
    All elements in argument 'x' to 'setDF' must be of same length 
In addition: Warning messages: 
1: In pyConnectionCheck() : R isn't connected to Python! 

2: In pyConnectionCheck() : R isn't connected to Python! 

3: In pyConnectionCheck() : R isn't connected to Python! 

4: In pyConnectionCheck() : R isn't connected to Python! 


$ 

Answer 1

检查Python是否通过使用函数pyIsConnected（）从R连接。如果没有，则使用pyConnect（）建立连接。

还要确保pattern.nlp软件包安装在Python中 - 请参阅http://www.clips.ua.ac.be/pattern
