嘗試在 Heroku 問題上部署 API 准備元數據 (pyproject.toml) 未成功運行

Question

我正在使用 Python 3.9.2。 開發 Flask API 並且我的代碼運行良好，我能夠在本地運行 API 並返回預期的數據，但我想將其部署到更多測試。

我嘗試在 requirements.txt 中降級我的 Numpy 版本，但仍然出現相同的錯誤。

               `numpy.distutils` is deprecated since NumPy 1.23.0, as a result
               of the deprecation of `distutils` itself. It will be removed for
               Python >= 3.12. For older Python versions it will remain present.
               It is recommended to use `setuptools < 60.0` for those Python versions.

Answer 1

在您的requirements.txt中嘗試設置錯誤消息所報告的較低版本的setuptools和numpy

要求.txt ：

...
setuptools==59.8.0
numpy==1.19.2
...

Answer 2

問題在於 Heroku 用於構建應用程序的 Python 版本。 我創建了一個 runtime.txt 文件並指定了修復該問題的 Python 3.9.12。
