available.packages does not work for local repo

[Zhenglei-BCS]

Anyone has encountered this issue below? I am trying to write up the unit test for the package but failed at the 1st step. Already tried to change the path into single quote, does not work.

The available.packages works for local packages but the internal logic is complicated. Could you show the path you used? It also checks the files at the directory to determine if it is a valid repository. Could you also show what files are at that directory? In principle there should be a PACKAGES (and PACKAGES.gz is recommended too)
