Question

我创建了一个unix minecraft发射器。它只在一个半小时前完成（截至9:30）。然后我明白了：

/home/axium1998/MinecraftMegaLauncher.sh: line 14: syntax error near unexpected token ~'$'do\r''. 
/home/Axium1998/MinecraftMegaLauncher.sh: line 14: 'do

我不知道是什么造成的。

# If code needs to be changed, just send me a PM saying something like: Project:MinecraftMegaLauncher Line #<line number> = <changed code>
# if it works (I bet it will, but for me to learn xP )it will be replaced/fixed.

编辑：可能不是确切的行。我上次上传后改变了它

我的猜测是您将脚本转换为Windows格式（可能是从Windows复制）然后您收到此错误：意外do\r，因为\r是意外的。

使用dos2unix进行转换。

unix bash语法错误附近意外令牌'do'
