无法在工具目录中安装 Sed，权限被拒绝

Question

我正在从头开始构建 Linux。这是我在安装 sed 过程中遇到的错误。

/tools/bin/install: cannot create regular file '/tools/bin/sed': Permission denied

因此我无法编译 Linux 头文件

/bin/sh: sed: command not found
Makefile:629: arch//Makefile: No such file or directory
make: *** No rule to make target 'arch//Makefile'.  Stop.
