Bash 意外标记“elif'”附近出现语法错误；（`elif[$ver==8]；然后'；）

这是该程序的来源，但当我试图启动它时，我犯了错误：

Pause 'Press [Enter] key to continue...'

当我从这个错误开始时：

./newscript.sh: line 89: syntax error near unexpected token `elif'
./newscript.sh: line 89: `      elif [ $ver == 8]; then'

我已经设置了chmod，并且已经用dos2unix转换了它 我还尝试了命令：

catspiget-Install.sh | sed'/\015/d'>newscript.sh

我怎样才能修好它

elif [ $ver == 7]; then: 
version="1.8.8"
elif [ $ver == 8]; then
version="1.8.7"`

在

elif[$ver==7]行中；然后：

您有

：

之后，这是导致错误的原因。只需删除

：

并在conditions中的每个

]

前面加上空格。

此外，

]

前面缺少空格。您可以考虑使用bash内置

选择vname[in word…]；do列表；已完成

，用于进行选择。
