安装python3-dev时出现的问题

Question

这个问题已经折磨了我两天了，如果没有python3-dev我就无法安装任何模块，有人可以告诉我如何解决这个问题吗？

The following packages have unmet dependencies:
     python3-dev : Depends: python3 (= 3.5.1-3) but 3.5.1-4 is to be installed
                   Depends: libpython3-dev (= 3.5.1-3) but it is not going to be installed
                   Depends: python3.5-dev (>= 3.5.1-2~) but it is not going to be installed
    E: Unable to correct problems, you have held broken packages.

Answer 1

您可以尝试安装libpython3-dev软件包而不是安装 python3-dev 软件包。
