如何从 apt-get 安装 python-dev？

Question

我试过这个和这个，这个和这个

这些都没有安装python-dev，我启动并运行了我的amd64系统，14.04，当我尝试安装wagtail，django cms时，出现错误：

     pysass.c:4:20: 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

    ----------------------------------------
    Cleaning up...
    Command /usr/bin/python -c "import setuptools, tokenize;__file__='/tmp/pip_build_root/
    libsass/setup.py';exec(compile(getattr(tokenize, 'open', open)(__file__).read().replace
    ('\r\n', '\n'), __file__, 'exec'))" install --record /tmp/pip-ojWg1O-record/install-
    record.txt --single-version-externally-managed --compile failed with error code 1 in

如何解决此问题并安装软件包？

这是因为缺少Python.h包含在python-dev包中的 c 头文件。

当我尝试上述链接时，它说：

apt-get install python-dev

Package python-dev is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
However the following packages replace it:
  python

E: Package 'python-dev' has no installation candidate

为了 apt-get install python2.7-dev

Package python2.7-dev is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package 'python2.7-dev' has no installation candidate

我研究了debian 档案并找到了一个软件包，python 2.7.8-1但无法安装。

在启动板上也试过这个，但不起作用。

你确定你做对了吗？

这是我的输出 # apt-get install python2.7-dev

root@olympus:/home/zeus# apt-get install python2.7-dev

尝试以 root ( su)身份执行此操作

此外，尝试运行# apt update并确保启用Multiverse 和 Universe（请参阅如何启用“Universe”存储库？）。我还在我的系统中启用了向后移植，不确定在这种情况下是否会有所不同。
