无法安装python-weka-wrapper

Question

我正在安装软件包python-weka-wrapper。但是我对Java开发工具包有疑问。

这是针对Windows 10上的python 3.7.4的。

C:\Users\dell>pip install python-weka-wrapper3

应该已经检查过Java版本：

C:\Users\dell>java -version
java version "1.8.0_231"
Java(TM) SE Runtime Environment (build 1.8.0_231-b11)
Java HotSpot(TM) 64-Bit Server VM (build 25.231-b11, mixed mode)

那么如何解决错误？谢谢！

Answer 1

您已经检查并找到Java运行时环境（JRE），而不是Java开发工具包，它是单独的安装。

您可以在oracle website上找到它。下载并安装，然后应该解决您的问题
