sudo -H proxychains4 python -m pip install pymupdf==1.14.21
我用了较低版本后，安装成功了。 但是现在eaf-open-browser打开baidu.com仍然报错，仍然没有什么详细错误日志可看
下面是我重新运行了一次安装命令，用于检查：

你崩溃的情况我无法重现，比较有效的调试方法就是在 eaf.py, core/browser.py, app/browser/buffer.py 三个文件中加上 print("******") 的代码，然后反复运行，查看 *eaf* buffer 的输出，可以暴力判定哪一行代码有问题，这样可以比较快速的修复问题。
我倒，我昨天还把log打到文件里面查coredump
class AppBuffer(BrowserBuffer): def __init__(self, buffer_id, url, config_dir, arguments, emacs_var_dict): print("AppBuffer init 1") BrowserBuffer.__init__(self, buffer_id, url, config_dir, arguments, emacs_var_dict, False, QColor(255, 255, 255, 255)) print("AppBuffer init 2")
上面的代码加了两行日志，崩溃的时候，eaf只显示了 “ApBuffer init 1”, 所以应该是BrowserBuffer__init__中有问题
class BrowserBuffer(Buffer): get_focus_text = QtCore.pyqtSignal(str, str) def __init__(self, buffer_id, url, config_dir, arguments, emacs_var_dict, fit_to_view, background_color): Buffer.__init__(self, buffer_id, url, arguments, emacs_var_dict, fit_to_view, background_color) print("BrowserBuffer init 1") self.add_widget(BrowserView(config_dir)) print("BrowserBuffer init 2")
这段只打印了BrowserBuffer init 1, 所以问题应该在self.add_widget(BrowserView(config_dir))
class BrowserView(QWebEngineView): open_url_in_new_tab = QtCore.pyqtSignal(str) open_url_in_background_tab = QtCore.pyqtSignal(str) translate_selected_text = QtCore.pyqtSignal(str) def __init__(self, config_dir): super(QWebEngineView, self).__init__() self.installEventFilter(self) self.config_dir = config_dir print("BrowserView init 1") self.web_page = BrowserPage() print("BrowserView init 2")
这段只打印了BrowserView init 1，所以BrowserPage对象构造的时候出了问题
class BrowserPage(QWebEnginePage): def __init__(self): print("BrowserPage init 1") QWebEnginePage.__init__(self) print("BrowserPage init 2")
QWebEnginePage.init(self) 这行有问题。追踪到此，难道还是QT的问题么？ 我对pyQT不熟悉，有什么一个简单的程序，可以运行诊断这个问题？
看着你的日志分析，非常像PyQt或者系统Qt的问题，应该和EAF无关。
是啊，现在要找个最简单的PyQt程序运行一下看看
可以Google一个最简单的PyQt5 Browser Demo测试一下。
创建t.py测试程序, 代码如下:
import sys from PyQt5.QtCore import * from PyQt5.QtWebEngineWidgets import * from PyQt5.QtWidgets import QApplication app = QApplication(sys.argv) web = QWebEngineView() web.load(QUrl("https://further-reading.net")) web.show() sys.exit(app.exec_())
python3-dbg t.py
Traceback (most recent call last): File "t.py", line 3, in <module> from PyQt5.QtCore import * ImportError: /usr/local/lib/python3.6/dist-packages/PyQt5/QtCore.abi3.so: undefined symbol: PyModule_Create2 Error in sys.excepthook: Traceback (most recent call last): File "/usr/lib/python3/dist-packages/apport_python_hook.py", line 63, in apport_excepthook from apport.fileutils import likely_packaged, get_recent_crashes File "/usr/lib/python3/dist-packages/apport/__init__.py", line 5, in <module> from apport.report import Report File "/usr/lib/python3/dist-packages/apport/report.py", line 30, in <module> import apport.fileutils File "/usr/lib/python3/dist-packages/apport/fileutils.py", line 23, in <module> from apport.packaging_impl import impl as packaging File "/usr/lib/python3/dist-packages/apport/packaging_impl.py", line 24, in <module> import apt File "/usr/lib/python3/dist-packages/apt/__init__.py", line 23, in <module> import apt_pkg ModuleNotFoundError: No module named 'apt_pkg' Original exception was: Traceback (most recent call last): File "t.py", line 3, in <module> from PyQt5.QtCore import * ImportError: /usr/local/lib/python3.6/dist-packages/PyQt5/QtCore.abi3.so: undefined symbol: PyModule_Create2
还没有找到解决办法
把用apt安装的 pyqt删除， 用 pip3 安装试试
你是将pip3软链接到了pip吗？不是的话，用pip3重新安装所有依赖试一下。我之前也遇到和你类似的问题：默认python是py3，我就认为pip安装的也是对应py3的。然后换成pip3就可以用了。
我是直接建了一个 virtualenv， 把 eaf-python-command 指向 env 下的python执行文件 ，把所有库都安装到 env 里面。目前用着还行。
在github或者gitee上分享一下你的virtualenv吧，折腾死了。
$ sudo apt list --installed | grep pyqt
WARNING: apt does not have a stable CLI interface. Use with caution in scripts.
之前就清理过一次
反其道而之，不采用pip install, 将所有sudo pip install 和 pip install的package卸载掉，然后只采用ubuntu18.04 apt提供的pyqt包。现在程序可以运行。但碰到一个问题，下面的程序在spacemacs的shell里面只能用sudo才能运行。
import sys from PyQt5.QtCore import * from PyQt5.QtWebEngineWidgets import * from PyQt5.QtWidgets import QApplication app = QApplication(sys.argv) web = QWebEngineView() web.load(QUrl("https://www.baidu.com")) web.show() sys.exit(app.exec_())
如果不用sudo运行，就会报错
Qt: Session management error: Could not open network socket [1:1:0202/170712.758765:FATAL:sandbox_linux.cc(180)] Check failed: sandbox::Credentials::MoveToNewUserNS(). #0 0x7fdb947dfaee <unknown> #1 0x7fdb947f20e2 <unknown> #2 0x7fdb944ede60 <unknown> #3 0x7fdb94033fe0 <unknown> #4 0x7fdb947be6d7 <unknown> #5 0x7fdb947bedf7 <unknown> #6 0x7fdb947b81c9 <unknown> #7 0x7fdb93e68b59 QtWebEngine::processMain() #8 0x5641b40efbf3 <unknown> #9 0x7fdb928d1b97 __libc_start_main #10 0x5641b40efc7a <unknown>
现在 eaf 中看到的也是这个错误。
如果直接在终端窗口里面运行上面的pyqt程序，正常，不需要sudo也可以运行。 但是一旦在spacemacs的shell中运行 python t.py 就会出现错误。错误如上所述。
现在咋办，难道emacs启动用sudo, 也太奇怪了吧。
终于搞定了！！
原因是.spacemacs.d/.spacemacs.env文件里面保留了proxychains4的环境变量，居然导致spacemacs启动的时候会自动使用proxychains4翻墙。 而proxychains4会导致pyqt程序崩溃，包括chromium-browser程序启动也会崩溃。 删除掉.env文件后正常了。
@manateelazycat 今天试着更为深度的集成 eaf， 感觉挺好用，贴出来大家讨论讨论

不知EAF的pdf阅读器能像pdf-tools一样和org-noter配合使用吗？
我不用org，主要嫌麻烦，欢迎patch
不知愿意分享一下对知识的管理? 我觉得 org 是最简单的办法. 如果不去系统管理知识,很多知识都用不上.
