我买了一台装有 Debian 10 的新笔记本电脑，并将我的.vimrc文件从旧笔记本电脑（Linux Mint）中移出。
当我运行 vim 时它说
Warning: Cannot find word list "de.utf-8.spl" or "de.ascii.spl"
到目前为止一切正常，但:set spell在 vim 中输入时出现：
:set spell
Cannot find spell file for "de" in utf-8
Do you want me to try downloading it?
Downloading de.utf-8.spl...
shell returned 127
**error** (netrw) /bin/bash: ftp: command not found

Could not find it, trying de.ascii.spl...
shell returned 127
**error** (netrw) /bin/bash: ftp: command not found

Sorry, downloading failed
Warning: Cannot find word list "de.utf-8.spl" or "de.ascii.spl"
Press ENTER or type command to continue
我不知道那里出了什么问题。我使用这个 .vimrc 文件好几年了。
