So I have upgraded to Julia v0.7 from v0.6. I am trying to convert my code. I get the following error:
ERROR: LoadError: LoadError: ArgumentError: Package xxx d
The error Package xxx does not have ExcelReaders in its dependencies means that xxxx does not have ExcelReaders in its dependencies (it is unrelated with the fact if you have installed ExcelReaders manually). I do not know what xxxx is so it is hard to check.
See https://docs.julialang.org/en/latest/stdlib/Pkg/#Adding-dependencies-to-the-project-1 for the details.
