Something wrong with -colorpalette-

[Chen Samulsion]

Dear Stata users,

I have installed the -colorpalette- wrote by Ben Jann, and I remenber that it run successfully before. I run it today but fails. I reinstall -colorpalette- and -colrspace-, but the problem still exists. Below is the information:

. version
version 16.0

. colorpalette
function pexists() not declared in class ColrSpace
(176 lines skipped)
(error occurred while loading colorpalette.ado)
r(3000);

I'm sorry to post the question before carefully examining. I find the reason is that I have installed -palettes- and -colrspace- more than once. The command runs well after removing older copies.

. adoupdate palettes colrspace
(note: ado update updates community-contributed files; type -update- to check for updates to official Stata)
(note: package mrtab was installed more than once; older copy removed)
(note: package palettes was installed more than once; older copy removed)
(note: package colrspace was installed more than once; older copy removed)

Checking status of specified packages...
