关于如何解决这个问题的任何想法？我真的需要将pyfftw安装到 conda 环境中，该环境已经有我需要的其他库，例如 tensorflow。直到知道，我只能为 python 3.9 正确安装其他库（即 tensorflow）。我正在使用 Mac M1。这是命令pip install pyfftw的错误输出：

PyPA 没有为osx-arm64托管预编译的轮子，因此它是从源代码构建的。根据文档，在构建源代码时，需要先安装 FFTW。幸运的是，Conda Forge 似乎正在构建它（包括osx-arm64），所以尝试

conda install -c conda-forge fftw

pip install pyfftw

否则，我向 Conda Forge feedstock 提出了一个问题，指出他们应该能够构建osx-arm64构建。希望这会向前发展，并且将来可以完全避免 Pip 和本地编译。

更新：现在正在为 osx-arm64 构建原料，因此您应该可以使用

conda install -c conda-forge pyfftw
