我是编程新手，我想安装flutter SDK，但无法继续传递错误消息：
E325: ATTENTION
Found a swap file by the name ".bash_profile.swp"
owned by: macbook dated: Thu May 16 12:30:19 2019
file name: ~macbook/.bash_profile
modified: YES
user name: macbook host name: macbooks-MBP
process ID: 1242
While opening file ".bash_profile"

(1) Another program may be editing the same file. If this is the case,
be careful not to end up with two different instances of the same
file when making changes. Quit, or continue with caution.
(2) An edit session for this file crashed.
If this is the case, use ":recover" or "vim -r .bash_profile"
to recover the changes (see ":help recovery").
If you did this already, delete the swap file ".bash_profile.swp"
to avoid this message.
Swap file ".bash_profile.swp" already exists!

如果有人可以一步一步地帮助我解决这个问题，那将是很棒的事情。
