I wondered whether you could help with an error I'm getting with SBCL. I'm doing a tutorial, and one of the first lessons is to load a script into LISP. Here's the script, called hello.lisp:
(defun hello ()
"say hello to USER"
(format t "hello ~a" (uiop:getenv "USER")))
(hello)
But when I run the command: (load "hello.lisp") I get the following error:
debugger invoked on a SB-C::INPUT-ERROR-IN-LOAD in thread
#<THREAD "main thread" RUNNING {1000510083}>:
READ error during LOAD:
Package UIOP does not exist.
Line: 3, Column: 36, File-Position: 74

Type HELP for debugger help, or (SB-EXT:EXIT) to exit from SBCL.
restarts (invokable by number or by possibly-abbreviated name):
0: [ABORT] Abort loading file "/home/oliver/Programs/hello.lisp".
1: Exit debugger, returning to top level.
(SB-C:COMPILER-ERROR SB-C::INPUT-ERROR-IN-LOAD :CONDITION #<SB-INT:SIMPLE-READER-PACKAGE-ERROR "Package ~A does not exist." {1001542543}> :STREAM #<SB-INT:FORM-TRACKING-STREAM for "file /home/oliver/Programs/hello.lisp" {10015403F3}>)
Any ideas on how I can fix? It seems I'm missing "UIOP" but I can't figure out how to install. Thanks in advance!

SOLUTION Please! add this (require :asdf) command line to .sbclrc file It will work.
(require :asdf)
(defun hello ()
"say hello to USER"
(format t "hello ~a" (uiop:getenv "USER")))
(hello)
