我们从Python开源项目中，提取了以下25个代码示例，用于说明如何使用pydoc.pager()。

Install using your Linux software packager for a noticeably better integrated experience. ---[Ubuntu/Debian/Mint/etc]-------------------------- python3-dev libmpv1 libmpv-dev python3-pyqt5 python3-pyqt5.qtopengl ffmpeg mediainfo ---[Arch Linux]-------------------------------------- python mpv python-pyqt5 ffmpeg mediainfo ---[Fedora]------------------------------------------ python3-devel mpv-libs mpv-libs-devel python3-qt5 ffmpeg mediainfo ---[openSUSE]---------------------------------------- python3-devel libmpv1 mpv-devel python3-qt5 ffmpeg mediainfo You need to build a Python extension module before you can run the app directly from source code. This is done for you automatically by the package installers but if you wish to simply run the app direct from source without having to install it (i.e. python3 setup.py install) you can do so by building the extension module with the following setuptools command, run from the top-most extracted source code folder: $ python3 setup.py build_ext -i And to then run the app directly from source, from the same top-most source code folder: $ python3 -m vidcutter To view all console output for debugging or general interest then append the debug parameter: $ python3 -m vidcutter --debug Make sure you build the extension module AFTER installing the dependencies covered above, in particular libmpv and the mpv + python3 dev headers are all needed for it to compile successfully. Compiled extension modules under vidcutter/libs will look like: mpv.cpython-36m-x86_64-linux-gnu.so [linux] mpv.cp36-win_amd64.pyd [win32] Windows users must do all this within a Visual Studio 2015/2017 Native x64/x86 Developer Command Prompt accessible from your Visual Studio program group via the start menu. It's easier to just grab the prebuilt Windows installers directly from: https://github.com/ozmartian/vidcutter/releases/latest ''')
