2021 年更新答案
截至 2021 年，最初的 Github 问题 (Python 3.8 Support) about supporting Python 3.8 with pmdarima has been resolved (with this PR [MRG+2] Python 3.8 support) 已关闭。现在可以用pip 21.x and Python 3.8.x and pmdarima 1.8.x:
正常安装
(tmp) tmp$ python3.8 -m pip -V
pip 21.2.4 from /usr/local/lib/python3.8/site-packages/pip (python 3.8)

另外，也可以用Python安装 3.9.x:

(tmp) tmp$ python3.9 -V

如果您仍然遇到安装问题，请确保更新到最新的 pip (21.x) 和 Python 版本（3.8、3.9），并安装最新的 pmdarima (1.8.x).
2019 年原答案
您似乎在使用 Python 3.8:
c:\users\dobri\appdata\roaming\python\python38\site-packages
Python 3.8 于 2019 年 10 月刚刚发布，预计（或者这并不奇怪）并非所有第三方软件包都完全支持它。事实上，pmdarima 的 Github 存储库中有一个支持 Python 3.8 的未决问题。见 https://github.com/tgsmith61591/pmdarima/issues/199:
Python 3.8 was released on 2019-10-14. It appears to be fully
backwards compatible, we just need to pre-build wheels for it.
Currently, some of our dependencies do not support 3.8, so we will
have to wait for them, but this issue is to track any conversation
around 3.8 support
请注意有关等待其依赖项支持 3.8 的部分，然后才能构建合适的轮子。您可以关注该票证 and/or post 您的安装问题，以便通知他们（请务必提供 完整 环境详细信息！）。
您现在可以做的最好的事情是 降级到 Python 3.7 并使用它来安装 pmdarima。它在 Python 3.7.5.
上安装正常
$ python -V
Python 3.7.5
$ python -m pip install pmdarima
...
Successfully installed Cython-0.29.14 joblib-0.14.0 numpy-1.17.4 pandas-0.25.3 patsy-0.5.1 pmdarima-1.4.0 python-dateutil-2.8.1 pytz-2019.3 scikit-learn-0.21.3 scipy-1.3.2 statsmodels-0.10.1
一旦 pmdarima 支持，就将您的 project/app/script 迁移到 Python 3.8。
存在持续性错误，所有要求均已满足。

Python 3.8 于 2019 年 10 月刚刚发布，预计（或者这并不奇怪）并非所有第三方软件包都完全支持它。事实上，pmdarima 的 Github 存储库中有一个支持 Python 3.8 的未决问题。见 https://github.com/tgsmith61591/pmdarima/issues/199:
Python 3.8 was released on 2019-10-14. It appears to be fully backwards compatible, we just need to pre-build wheels for it. Currently, some of our dependencies do not support 3.8, so we will have to wait for them, but this issue is to track any conversation around 3.8 support
请注意有关等待其依赖项支持 3.8 的部分，然后才能构建合适的轮子。您可以关注该票证 and/or post 您的安装问题，以便通知他们（请务必提供 完整 环境详细信息！）。
您现在可以做的最好的事情是 降级到 Python 3.7 并使用它来安装 pmdarima。它在 Python 3.7.5.
$ python -V
Python 3.7.5
$ python -m pip install pmdarima
...

一旦 pmdarima 支持，就将您的 project/app/script 迁移到 Python 3.8。
