在 Openshift 期间安装 pyodbc Build/Deployment

Question

在我的 Openshift 部署中安装 pyodbc 时出现错误。有许多线程解释了解决方案，包括这个：

错误：

Building wheel for pyodbc (setup.py): started
  Building wheel for pyodbc (setup.py): finished with status 'error'
  error: subprocess-exited-with-error
  
  × python setup.py bdist_wheel did not run successfully.
  │ exit code: 1
  ╰─> [10 lines of output]

      compilation terminated.

      [end of output]
  
  note: This error originates from a subprocess, and is likely not a problem with pip.
  ERROR: Failed building wheel for pyodbc

我的问题是：如何在我的部署中启动 apt 安装（或 sudo）？我正在使用 OpenShift GUI。

我正在使用 requirements.txt 强制安装所有依赖项的 PIP：

pandas
numpy
dash
dash_core_components
dash_html_components
plotly.express
dash
plotly
sqlalchemy
matplotlib
pyodbc
powershift-image

为了解决我的问题，我必须创建自定义 Docker 文件并将应用程序作为 Docker 映像部署到 OpenShift 中。具体来说，我在 GUI 中使用了 add --> from Dockerfile 而不是 add--> Import from Git (Python builder image)。从 Git 导入方法不允许足够的灵活性来安装所有需要的包。（pyodbc 等）
