我正在尝试使用github的参考建立供应链区块链。我已经修改了链码的内容，并尝试使用以下命令更新链码：
peer upgrade -name of the file
但是在出现错误之后：
Command 'peer' not found, did you mean:
command 'pee' from deb moreutils
command 'peet' from deb pipexec
command 'pear' from deb php-pear
command 'seer' from deb seer
command 'beer' from deb gerstensaft
Try: sudo apt install <deb name>
请有人帮助
