每次我尝试安装任何软件包时 pip 都会失败

Question

我的 pip 不适用于任何包：

 regex_3/_regex.c:46:20: fatal error: Python.h: No such file or directory
     #include "Python.h"
                        ^
    compilation terminated.
    error: command 'x86_64-linux-gnu-gcc' failed with exit status 1

当我试图通过

解决这个问题时

sudo apt-get install python3-dev

我知道了：

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created

The following information may help to resolve the situation:

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.

我无法安装任何这些依赖项！谁能帮帮我。

Answer 1

您应该能够通过以下方式查看持有的包裹列表：

apt-mark showhold 

然后通过

取消持有它们

sudo apt-mark unhold <package name>

之后，您应该能够删除冲突的软件包，然后重新安装所有。

尝试删除所有未满足的依赖项，然后重新安装。
