A bug about freeAlgebra

[wp-hhh]

I am learning Macaulay2 now. When I try to use the method "freeAlgebra(QQ,{x,y,z})" to create a free algebra as shown in the example of the documentation, where the example is in the website, "https://macaulay2.com/doc/Macaulay2/share/doc/Macaulay2/AssociativeAlgebras/html/_free__Algebra.html", I get a mistake as shown in the fig.1. When I try to use it online, I also get the mistake as shown in the fig.2. Do I do something wrong or are there some bugs in the method "freeAlgebra"?

You need to run the command

needsPackage “AssociativeAlgebras”

before using any of the noncommutative functionality.

Best, Frank

OK, I solved it by your advice.

Thanks.
