ModuleNotFoundError：尝试安装 numpy 1.16 时没有名为“distutils.msvccompiler”的模块

Question

我正在 conda 环境中工作，我正在尝试将 numpy 降级到版本 1.16，但运行时

pip install numpy==1.16

我不断收到以下错误：

$ pip install numpy==1.16

      `setup.py clean` is not supported, use one of the following instead:
      
        - `git clean -xdf` (cleans all files)
        - `git clean -Xdf` (cleans all versioned files, doesn't touch
                            files that aren't checked into the git repo)
      
      Add `--force` to your command to use it anyway if you must (unsupported).

我该如何解决这个问题？

似乎可以解决这个问题的是安装特定版本的setuptools（<65) into the conda environment:

conda install "setuptools <65"
