无法启动 FSLint

运行 Ubuntu 18.04 并想尝试运行 FSLint 来清除一些空间，但遇到了问题......

$ fslint-gui 
Traceback (most recent call last):
  File "/usr/bin/fslint-gui", line 27, in <module>
    import gtk
ImportError: No module named gtk

我查了一下，有一个建议

$ pip install pygtk
Collecting pygtk
  Using cached https://files.pythonhosted.org/packages/7c/18/fa4f2de77500dd62a314fd845ff6e903ac2ce551164cb421c5750969f799/pygtk-2.24.0.tar.bz2
    Complete output from command python setup.py egg_info:
    ********************************************************************
    * Building PyGTK using distutils is only supported on windows. *
    * To build PyGTK in a supported way, read the INSTALL file.    *
    ********************************************************************

    ----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-build-zgzLmi/pygtk/

当那失败时我尝试了apt。

$ sudo apt install --install-recommends python-gtk2

python-gtk2 is already the newest version (2.24.0-5.1ubuntu2).

然后我想也许模块隐藏在dev。

$ sudo apt install --install-recommends python-gtk2-dev

好吧，我顺着依赖关系线索往下走，却走进了死胡同。

或已移出接收状态。以下信息可能有助于解决此情况：

The following packages have unmet dependencies:
 libfontconfig1-dev : Depends: libfontconfig1 (= 2.12.6-0ubuntu2) but 2.12.6-0ubuntu2.3 is to be installed

您认为该如何解决这个问题？

附加信息

不久前我用简单的安装了它sudo apt install fslint。

我按照 N0rbert 的说法运行了以下命令：

$ sudo apt-get install fslint libglade2-0 python-cairo python-glade2 python-gobject-2 python-gtk2

which python给我/usr/local/bin/python

只需输入即可python打开

Python 2.6.6 (r266:84292, Nov 20 2019, 15:47:02)
[GCC 7.4.0] on linux4

我甚至尝试了purge和，install但fslint没有任何依赖项被重新安装。我甚至sudo apt install -f没有成功。

darksky 的其他更新

Python 2.6.6。那可能是你的问题。默认的 python 2 应该是 2.7。你可以尝试一下sudo apt install python2，确保运行 时它是 2.7 python2，然后fslint-gui再次运行吗？

事实上，你的 python 就在那里/usr/local/bin，没有/usr/bin告诉我你或其他人已经手动安装了它，可能是从源代码安装的。

我认为我没有进行过源代码构建。make这通常会导致缺少依赖项。首次安装系统时是否已预装 python？也许我应该从备份操作系统安装（16.04）中复制一些文件。

另外，通过运行 sudo update-alternatives --config python 确保将您的 python 指向 python2，并确保它指向 python2 或 python2.7，而不是 2.6 的任何内容。

$ sudo update-alternatives --config python
update-alternatives: error: no alternatives for python

答案1

18.04 发行版的默认 Python 2 版本始终是 2.7。如果你只是sudo apt install python在 18.04 中运行，你最终会得到一个/usr/bin软链接到的Python 2.7 /usr/bin/python2.7。你有不知何故在您的系统中安装了 python2.6 /usr/local，它似乎优先于 2.7。您需要做的第一件事是确保 2.7 再次成为默认值。

一个简单的方法是将您的重命名/usr/local/bin/python为/usr/local/bin/python2.6。如果有 ，/usr/local/bin/python2您可能也想将其删除。最后，当您这样做时，您which python应该会看到/usr/bin/python。如果您运行，ll /usr/bin/python您应该会看到/usr/bin/python -> python2.7*。您还可以python2通过创建sudo ln -s /usr/bin/python2.7 /usr/bin/python2以进一步兼容需要python2特定程序的程序。

Python 是操作系统的重要组成部分，并且很多依赖它的软件包，包括程序fslint。因此，如果您的系统范围的 Python 不是 18.04 通常附带的，您可能会遇到奇怪的依赖问题。

最后，您不需要-devpython 的版本，因为您没有编译任何依赖于源代码中的 python 头文件的东西。
