When updating packages, the following error was issued. (JuliaPro_v0.6.2.2_build-321 on Windows 10 Pro)
This is probably the same as the errors in Error with NullableArrays when trying to install or remove packages or run Pkg.update() - #6 by Harsha . Do the instructions posted there help?
Also please post code by copying and pasting it, rather than including a screenshot. Screenshots are harder to read and generally impossible to search, among other reasons.

Thank you for your advice and the pointer.
I’ve followed the instructions in the link, but haven’t been able to fix the error.
I found the file REQUIRE under …\v0.6\Requires folder, which had a line
julia 0.6.0-pre.beta.450
I first deleted the line, but it didn’t work.
I changed the line to the following cases, including
julia 0.6.2+
julia 0.6+
but still get the error message as follows:
julia> Pkg.resolve()

Er, no, that doesn’t look right. The file you should be changing is ...\v0.6\REQUIRE, and you need to change the line with Compat. See Error with NullableArrays when trying to install or remove packages or run Pkg.update() - #6 by Harsha
It looks like you edited the wrong file (...\v0.6\Requires\REQUIRE) and changed the wrong line (the julia requirement itself).

Sorry I edited the wrong file.
Yes, it worked! 
I opened the file REQUIRE in the folder …\JuliaPro-0.6.2.2\pkgs-0.6.2.2\v0.6, and changed
Compat 0.55.1 0.55.1+
to
Compat
Then, Pkg.resolve() worked fine!
Many thanks.
