错误：命令“/usr/bin/clang”失败，退出代码为 1

Question

I download a not commonly-used software package in github in Mac M1. I am trying to compile and install myself according to the instruction.

I have encountered the following problem saying "command/usr/bin/clang with exits error 1". I did install xcode in my mac. Because the built-in gcc version is 4.2, I upgrade the version using brew install gcc@7 command and the link to this gcc version. But I still face the same compiling problem.

Does anyone have instructions for me how to solve this? The author did not maintain the source code anymore and I have struggled for one day and still can not fix the problem.

The follow steps worked!

1. upgrade pip and related components by:

python -m pip install --upgrade pip
pip install –upgrade wheel 
pip install –upgrade setuptools

2. install openssl

brew install openssl re2

3. reinstall your package with some environment to be set

LDFLAGS="-L$(/opt/homebrew/bin/brew --prefix openssl)/lib -L$(/opt/homebrew/bin/brew --prefix re2)/lib" CPPFLAGS="-I$(/opt/homebrew/bin/brew --prefix openssl)/include -I$(/opt/homebrew/bin/brew --prefix re2)/include" GRPC_BUILD_WITH_BORING_SSL_ASM="" GRPC_PYTHON_BUILD_SYSTEM_RE2=true GRPC_PYTHON_BUILD_SYSTEM_OPENSSL=true GRPC_PYTHON_BUILD_SYSTEM_ZLIB=true pip install <your package name>
