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](https://discourse.julialang.org/t/error-with-nullablearrays-when-trying-to-install-or-remove-packages-or-run-pkg-update/11225/6)

It looks like you edited the wrong file (`...\v0.6\Requires\REQUIRE`) and changed the wrong line (the `julia` requirement itself).
