这个错误可能是由于 pyqt5==5.15.0 的构建要求问题导致的。建议检查一下相关要求是否正确，并确保已安装必要的构建依赖项。另外，也可以尝试更新 pip 版本，然后再次运行安装命令。需要注意的是，这个问题不是由 pip 引起的，而是由这个包本身引起的。如果问题仍然存在，请尝试联系包的开发人员获取更多帮助。

ERROR: Command errored out with exit status 1: command: 'D:\software\Anaconda3\python.exe' 'D:\software\Anaconda3\lib\site-packages\pip' install --ignore-installed --no-user --prefix 'C:\Users\calm\AppData\Local\Temp\pip-build-env-nqacz0u_\overlay' --no-warn-script-location --no-binary :none: --only-binary :none: -i http://pypi.mirrors.ustc.edu.cn/simple --trusted-host pypi.mirrors.ustc.edu.cn -- 'sip >=6.6.2, <7' 'PyQt-builder >=1.14.1, <2'

这似乎是一个pip安装包的命令错误。根据你提供的命令，尝试使用以下命令进行安装：

pip install --ignore-installed --no-user --prefix 'C:\Users\calm\AppData\Local\Temp\pip-build-env-nqacz0u_\overlay' --no-warn-script-location --no-binary :none: --only-binary :none: -i http://pypi.mirrors.ustc.edu.cn/simple --trusted-host pypi.mirrors.ustc.edu.cn 'sip >=6.6.2, <7' 'PyQt-builder >=1.14.1, <2'

请确保你的网络连接正常，并且你的pip已经升级到最新版本。如果问题仍然存在，请提供完整的错误信息以便我更好地帮助你解决问题。
