Docker在映像构建中不接受pyOBDC

Posted 2023-02-27

我正在尝试为我的python应用程序构建q docker映像。但是每次运行Docker构建时，都会出现下一个错误。

Building wheels for collected packages: pyodbc, matplotlib, fpdf, pandas, MarkupSafe

如果我从我的requirements.txt中删除pyODBC，它将生成而没有问题。我的requirements.txt包含：

Flask==1.1.1
pyodbc==4.0.27
matplotlib==3.1.1
fpdf==1.7.2
pandas==0.25.1

答案

我认为您必须安装：

sudo apt-get install unixodbc unixodbc-dev

在我们的Docker文件中。
