我正在尝试从Tools tab
打开包管理器,我收到以下错误:

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
可能出现什么问题?
答案 0 :(得分:3)
实际上,您的文件系统中存在的目录是MultiObje c
tiveEvolutionaryFuzzyClassifier,而没有&#39; c&#39; 。自己改变它,你会让它运作良好:))
