【问题描述】：

我正在尝试通过以下命令在 Google Colab 上安装 "gmpy2"：

!pip3 install gmpy2

我收到错误：

pip3 --version
pip 21.1.3 from /usr/local/lib/python3.7/dist-packages/pip (python 3.7)

为什么我不能安装 "gmpy2" ？出现此错误的原因可能是什么？

【问题讨论】：

gmpy2.readthedocs.io/en/latest/intro.html#installation 非python要求都安装了吗？

【参考方案1】：

这里是如何安装gmpy2：

!apt install libmpc-dev
!pip install gmpy2
