Installation Error Version 1.19.1: error: key not found in dictionary

[sankhaneel bisui]

Hi, 

I hope you are doing well. I installed Macaulay2 Version-1.19.1 on my apple device with macOS Mojave (version-10.14.6). I followed the instructions as described on the website. I can start Macaulay2 in emacs, but it begins with the following error message and other notes. 

/Applications/Macaulay2-1.19.1/share/Macaulay2/Core/packages.m2:424:124:(1):[67]: error: key not found in dictionary

I tried to load some packages, but that did not work. I am attaching the screenshot of the error and notes. I wondered whether the old version of macOS was causing the trouble. Has anyone faced similar situations before? 

I also tried to install M2 using brew, but that did not work out. So I installed it by downloading the .dmg file. I do not know what to do at this point. I appreciate any help you can give me. 

Thanks in advance.

You seem to have some old packages installed in your "user application directory", `~/Library/Application Support/Macaulay2/`.  If you add `-q` to the M2 command line, it should work.  If that does work, you can remove those old packages with `uninstallAllPackages()`, and then you won't need the `-q`, and you can re-install those packages, after first checking that they work.

Thank you, Dr. Grayson, this works.
