I cannot install NLopt



I have trouble installing NLopt package. The error message is shown below. I’d appreciate any help on this.

You appear to be affected by the GitHub TLS change (see Errors for Git / Pkg). Try running Pkg.update() which should install the new BinDeps.jl to fix this issue.


That solved my problem. Thank you.
