python - ERROR : a package requires another one, 未安装，Python

Question

我正要安装一个 python 包，但它说

(base) E:\codementor\Project>pip install importlib-resources
Collecting importlib-resources

所以我尝试安装另一个包(dill)

自从pip安装了一个pypi包相关的所有依赖后，我至今还没有体验过。我不明白为什么会这样。有什么办法可以解决吗？

Answer 1

我通过重新安装上层包解决了这个问题。

pip install tensorflow-datasets
pip install apache-beam

我不确定为什么没有提前安装所需的包。
