每当我安装需要 python3-dev 的东西时，它都会显示以下消息：
The following packages have unmet dependencies:
python3-dev: Depends: python3 (= 3.6.7-1~18.04) but 3.6.7-1~18.04 is installed
Depends: libpython3-dev (= 3.6.7-1~18.04) but 3.6.7-1~18.04 is installed
我该如何修复这个问题？运行 Linux mint 18 XFCE
编辑：我尝试在这里重新安装 python3：
lukaka@Lukaka-Minecraft-PC:~$ sudo apt-get install --reinstall python3

You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
python3-dev : Depends: python3-distutils (>= 3.6.7-1~) but 3.6.5-3 is to be installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).

答案1
您可以尝试安装包libpython3-dev而不是安装包 python3-dev。
就我而言，我尝试通过 pip 安装 webrtcvad，但出现编译错误
> cbits/pywebrtcvad.c:1:10: fatal error: Python.h: No such file or directory
我在网上搜索并被建议安装包 python3-dev。
但是我在安装 python3-dev 时遇到了完全相同的错误。
安装libpython3-dev之后，我成功通过pip完成了webrtcvad的安装。
希望它能帮助你。
