执行脚本 fbs_pyinstaller_hook 失败

Question

我正在尝试从我的 PyQt5 应用程序创建一个可执行文件。我的系统规格：

• ubuntu 18.04
• python (3.6.9)
• fbs (0.8.9)
• matplotlib (3.3.0)
• numpy (1.19.1)
• 熊猫 (1.1.0)

我正在关注fbs tutorial 从我的应用程序构建一个可执行文件。我使用fbs run 命令运行应用程序时没有出错。

fbs freeze 命令产生以下输出：

-c:12: MatplotlibDeprecationWarning: 
The matplotlib.backends.backend_qt4agg backend was deprecated in Matplotlib 3.3 and will be removed two minor releases later.
Done. You can now run `target/DataVisualization/DataVisualization`. If
that doesn't work, see https://build-system.fman.io/troubleshooting.

但我在我的代码中将matplotlib.backends.backend_qt4agg 的5 版本导入为：

from matplotlib.backends.backend_qt5agg import FigureCanvasQTAgg, NavigationToolbar2QT as NavigationToolbar

当我从

运行可执行文件时

~/MyProject/target/AppName

我收到此错误：

./AppName

我已经检查了这些链接中给出的解决方案，但没有一个能派上用场！

• The most common mistake
• Failed to execute script fbs_pyinstaller_hook for pyqt5 gui application

有什么想法吗？

Answer 1

我完全放弃了使用 FBS。pyinstaller 非常适合编译 PyQt5 代码。尝试只使用 pyinstaller 看看是否有效。
