Python 3.x 无法使用pip在windows上安装h5py

我使用的是python版本3.8.5，在Windows1064位上使用的是pip版本20.2.4。 我需要安装h5py来安装Keras库，我在cmd中为其运行命令pip install h5py。这给了我以下错误：

当我使用pip安装keras直接安装keras时，我会遇到同样的问题，因为这也需要h5py。我正在使用pycharm，甚至从那里安装keras都显示出一个错误，我认为这是由于h5py造成的。我在尝试安装keras时也遇到了这个问题，但是这个命令帮助我安装了h5py和keras所需的所有依赖项：

pip install versioned-hdf5

在此之后，我还可以成功地安装keras。该命令还下载h5py。
