我正在尝试从Tools tab打开包管理器，但出现以下错误：

A problem has occurred whilst trying to get all package information. Trying a cache refresh...
Refresh in progress. Please wait...
然后下载默认的程序包管理器：
[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正确放置在
C:\Users\user\wekafiles\repCache\MultiObjectiveEvolutionaryFuzzyClassifier目录中有什么事吗
最佳答案
实际上，文件系统中存在的目录是MultiObje c tiveEvolutionaryFuzzyClassifier，不带'c'。自行更改，即可正常使用：）
