Weka 3.8 包管理器不工作

Question

我试图从 Tools tab 打开程序包管理器，但出现以下错误：

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

    at weka.gui.GUIChooserApp.run(GUIChooserApp.java:822)
A problem has occurred whilst trying to get all package information. Trying a cache refresh...
Refresh in progress. Please wait...

然后它会下载默认包管理器：

[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：文件 versions.txt 已正确放置在 C:\Users\user\wekafiles\repCache\MultiObjectiveEvolutionaryFuzzyClassifier 目录中

有什么问题吗？

Answer 1

实际上，您的文件系统中存在的目录是没有 'c' 的 MultiObjectiveEvolutionaryFuzzyClassifier。自己改，就可以了:)
