我在 Mojave 上使用 lldb 和 Xcode 10.2.1。一旦命令“运行”到 lldb,就会发生这种情况:
(lldb) target create "<executable>"
Current executable set to '<executable>' (x86_64).
(lldb) run
Process 95857 launched: '/Users/<path to executable>' (x86_64)
Process 95857 stopped
* thread #2, stop reason = exec

我尝试查找与 dyld`_dyld_start 打印输出相关的问题,因为这是我能想到的唯一线索。我读到这可能与尝试重新运行可执行文件有关,尽管我不太确定所描述的内容。
我应该能跑得这么好。它可以在其他具有较旧操作系统的计算机上运行。
我正在尝试在 Mac OS mojave 中使用 brew 安装 vim,我可以通过在终端中引入整个方向来使用它,但是当我输入vim它时使用默认一个,当我构建它时它显示了这个错误:

我正在编写一个 PyQt 应用程序,我必须添加一个补丁,以便字体在启用暗模式的 macos 上可读:
app = QApplication([])
# Fix for the font colours on macos when running dark mode
if sys.platform == 'darwin':
p = app.palette()
p.setColor(QPalette.Base, QColor(101, 101, 101))
p.setColor(QPalette.ButtonText, QColor(231, 231, 231))
app.setPalette(p)
main_window = MainWindow()
main_window.show()
app.exec_()
Run Code Online (Sandbox Code Playgroud)
这个补丁的问题是它使 macos 上的灯光模式变得不可读。
有没有办法可以从 python 或通过子进程使用标准 shell 命令检测 macos 上的暗模式?
编辑:从 PyQt 5.12 开始,不再需要暗模式修复。
enter action在Mac上的IntelliJ IDE上,默认的键盘快捷键是:cmd+ shift+ A。
当我输入此快捷方式时,会弹出一个奇怪的终端弹出窗口。
如何恢复该默认快捷方式正常工作?
