Weka 3.8包管理器不工作

Question

我试图从Tools tab打开包管理器，并得到以下错误：

C:\Users\user\wekafiles\repCache\MultiObjectiveEvolutionaryFuzzyClassifier\versions.txt (The system cannot find the path specified)
    java.io.FileInputStream.open0(Native Method)

A problem has occurred whilst trying to get all package information. Trying a cache refresh...

然后下载默认的Package：

[DefaultPackageManager] downloaded 13 KB
[DefaultPackageManager] downloaded 16 KB
[DefaultPackageManager] downloaded 28 KB
[DefaultPackageManager] downloaded 50 KB
[DefaultPackageManager] downloaded 67 KB
[DefaultPackageManager] downloaded 75 KB
...[DefaultPackageManager] downloaded 1666 KB

并再次输出相同的错误。

注意: versions.txt文件正确地放置在C:\Users\user\wekafiles\repCache\MultiObjectiveEvolutionaryFuzzyClassifier目录中。

有什么不对的？

Answer 1

实际上，文件系统中存在的目录是MultiObjectiveEvolutionaryFuzzyClassifier，没有“c”。你自己去改变它，你会让它运行得很好：)
