在linux安装蜂鸟E203的编译工具gcc时候报错
解决方案结果
…/Makefile:78: recipe for target ‘rv32ui-p-simple’ failed make: *** [rv32ui-p-simple] Error 127)

根据报错（对比着看）
make: /home/ubuntu/e203_hbirdv2/riscv-tools/riscv-tests/isa/…/…/prebuilt_tools/prefix/bin/riscv-nuclei-elf-gcc: Command not found
找不到riscv-nuclei-elf-gcc的位置
这里用查找：
find / -name riscv-nuclei-elf-gcc
找到之后RISCV_PREFIX,这个参数，重新定位gcc-riscv工具链
sudo nano Makefile
更改Makefile第32行的
linux指令里面两个点“…”代表向上一级，数一下。
成功啦！！
