【问题描述】：

我想在树莓派 3 上安装 glpk。我使用由 venv 创建的虚拟环境 testEnv。

python3 -m venv testEnv

我已经成功安装pyomo

python3 -m pip install pyomo

但是当我尝试时

python3 -m pip install glpk

我收到以下错误：

(testEnv) pi@raspberrypi:~/Desktop/MA-AU/Software-Test $ python3 -m pip install glpk

【参考方案1】：

当您在尝试安装 Python 库时收到有关缺少 .h 文件的错误时，原因通常是 Python 库依赖于 C 库，而 Python 包找不到该库 — 可能是因为您尚未安装它！

在这种情况下，运行 apt-get install libglpk-dev 应该会为您获取必要的库和标头。

【讨论】：

感谢您的提示！ :) 我必须从虚拟环境内还是外部执行此命令？还是有关系？

没关系；这是一个操作系统级别的命令，对 Python 的虚拟环境一无所知。

完美！成功了，你拯救了我的一天！ :)
