所有浏览器为基础的应用都可以响应 emacs 的 scroll-other-window
比如PDF和Org的预览应用， 分屏后， 光标专注在 emacs buffer 编辑， 可以直接用 scroll-other-window 操控预览进行上下滚动， 而不需要来回切换窗口
Shouldn’t we discourage to use sudo pip?
pip perhaps include by python2, i suggest use python3 and pip3
IIUC, the point is sudo, not py2/py3.
Besides, using sudo pip install will result in file conflicts when installing a package using pacman which contains the same files.
1 加载eaf抱错是因为没有在前面启动dbus-launch,已经解决
2 安装PyMuPDF,报错fitz.h找不到，不知道是不是要源代码安装mupdf,直接在debian9下aptitude安装，同样报错
3 pip3里面安装pyqt5,找不到包
You should paste error messages
善用debian的apt-file search foo.h
PyMuPDF报错

pyqt报错
user@debian:~$ sudo pip3 install pyqt5 [sudo] password for user: Collecting pyqt5 Could not find a version that satisfies the requirement pyqt5 (from versions: ) No matching distribution found for pyqt5
谢谢 马上尝试
安装了mupdf库文件，跟着报了一大堆错误，弄不了了，毕竟是一个医生，等大神以后弄得更傻瓜化再来尝试吧，感谢上面几位好心的朋友给我解答，也感谢大神的开发，谢谢谢谢！！！
你安装的是 Debian, debian太老了， 安装一个包更新的发行版，比如 deepin/ubuntu/archlinux
现在应用程序可以通过 send_keystroke 接口来读取 eaf buffer 的Emacs快捷键了： Add eaf-dired-open-file to make pdf/video/image default binding eaf · emacs-eaf/emacs-application-framework@eb18641 · GitHub
比如， 现在按 M-f 和 M-b 可以在浏览器中前进后退了。
无意中发现，用eaf打开pdf时，用鼠标滚轮不会加载新页，而且有时窗口贴合会错位。
窗口有错位都是因为 xlib reparent 没有很好的执行， 你用的啥系统和啥窗口管理器？
滚轮那个是已知问题， 还在调查原因。
Manjaro Deepin
你用一下KDE使一下，排除一下窗口管理器的问题
安装好了archlinux,相关的库都正常安装，但是eaf open 打开文档 视频 图片都报错，如下
Importerror: libqt5webenginewidgets.so.5:cannot open shared object file:no such file or directory
Pacman 安装的python-pyqt5
更新到最新版， 然后用 pip install pyqt5, 现在不需要 pacman 来安装 pyqt5 了
更新了，pip里面没有 pyqt5,显示
No mamatching distribution found pyqt5
我的系统是I686,已经是最新了
