本文介绍了如何解决在使用pip安装程序时遇到的错误，特别是针对未知参数'-mno-fused-madd'的问题，并提供了设置环境变量ARCHFLAGS来规避此问题的方法。

pip安装程序错误

clang: error: unknown argument: '-mno-fused-madd' [-Wunused-command-line-argument-hard-error-in-future]

clang: note: this will be a hard error (cannot be downgraded to a warning) in the future

error: command 'cc' failed with exit status 1

Projects using invalid compiler options will need to be changed to remove those options.

To help ease that transition, the compiler will temporarily accept an option to downgrade the error to a warning:

-Wno-error=unused-command-line-argument-hard-error-in-future

To workaround this issue, set the ARCHFLAGS environment variable to downgrade the error to a warning.

For example, you can install a Python native extension with:

ARCHFLAGS=-Wno-error=unused-command-line-argument-hard-error-in-future easy_install ExtensionName

Similarly, you can install a Ruby Gem with:

ARCHFLAGS=-Wno-error=unused-command-line-argument-hard-error-in-future gem install GemName (16214764)

Note: This option will not be supported in the future.
