无法在 Python3 中升级 pycairo

Question

我正在尝试升级pycairo软件包，但收到以下错误：

$ python3 -m pip install -U pycairo 

Defaulting to user installation because normal site-packages is not writeable

File 意味着您必须使用 C/C++ 标头进行安装，因为它必须编译一些 C/C++ 代码。Python.hpython-dev.h在Linux Mint/Ubuntu/Debian上，它可能是这个命令之一。apt install python-devapt install python3-devapt install python3.7-dev
