shell中带双引号的命令无法执行

Question

我执行下面脚本的时候会报错，但是我手动执行echo的命令就不会报错，明明是一样的！

我尝试在Linux、Windows中执行这个脚本，它们都报同样的错误。虽然在Linux上没有命令MinGW Makefiles，但即使有，也会被举报。因为错误提示是Could not create named generator "MinGW而不是Could not create named generator "MinGW Makefiles"

我该如何解决这个问题？

#!/bin/bash

compiler_options=(' -G "MinGW Makefiles"')

echo "cmake -S . -B build ${compiler_options}"
cmake -S . -B build ${compiler_options}

# run command
bash test.sh

# errorinfo
CMake Error: Could not create named generator "MinGW

Answer 1

使用数组的目的是避免将所有参数塞入一个whitespace-delimited字符串。

#!/bin/bash

compiler_options=(-G "MinGW Makefiles")

echo "cmake -S . -B build ${compiler_options[*]}"
cmake -S . -B build "${compiler_options[@]}"
