尝试在virtualenv中安装pyodbc时出错

Question

我正在尝试在虚拟环境中安装pyodbc。以下命令行命令显示了这些步骤：

>python3.9 -m venv .venv
>source .venv/bin/activate
>pip install pyodbc

然后我得到以下错误：

我正在使用wsl ubuntu。在我的wsl系统中，我已经成功地安装了pyodbc，但在虚拟环境中却无法实现。我做错了什么

Answer 1

我通过在linux上安装python3.9-dev解决了这个问题：

> sudo apt-get install python3.9-dev
