如何用pyrcc5编译resources.qrc文件

Question

我正在尝试为QGIS 3(我使用的是Windows 10)制作一个插件，但在创建它之前，它会显示以下消息：

"The resource compiler pyrcc5 was not found in your path. You'll have to manually compile the resources .qrc file with pyrcc5 before installing your plugin".

这是一个挫折，因为在pyqgis中设置插件路径后，它会部署，但是插件说它找不到类模块。

我已经设法制作了一个插件，但在调用它的classFactory()方法时它显示错误，因此我认为这是因为我未能编译pyrcc5。

在选择了不能加载插件'remove_feature'后，它带来了这个错误，因为调用它的classFactory()方法时发生了错误：

ModuleNotFoundError: No module named 'remove_feature.resources' 
Traceback (most recent call last):

Answer 1

在OSGeo4W外壳程序中，运行qt5_env.bat和py3_env.bat。然后，将目录更改为

C:\Users\Arnold Kilaini M\AppData\Roaming\QGIS\QGIS3\profiles\default\python\plugins\mmqgis".

运行pyrcc5 -o resources.py resources.qrc

此外，我还找到了一个与您的gis.stackexchange问题相关的link：

希望这能有所帮助！

Answer 2

使用这个.bat，我没有任何问题，艾莫尔。

@echo off
SET QGIS_ROOT=C:\GIS\QGIS
call "%QGIS_ROOT%"\bin\o4w_env.bat
call "%QGIS_ROOT%"\apps\grass\grass78\etc\env.bat

path %PATH%;%QGIS_ROOT%\apps\qgis\bin
path %PATH%;%QGIS_ROOT%\apps\grass\grass78\lib
path %PATH%;C:\GIS\QGIS\apps\Qt5\bin
path %PATH%;C:\GIS\QGIS\apps\Python37\Scripts

set PYTHONPATH=%PYTHONPATH%;%QGIS_ROOT%\apps\qgis\python
set PYTHONPATH=%PYTHONPATH%;%QGIS_ROOT%\apps\Python37\lib\site-packages

set PYTHONHOME=%QGIS_ROOT%\apps\Python37
set QT_PLUGIN_PATH=%QGIS_ROOT%\apps\qgis\qtplugins;%QGIS_ROOT%\apps\qt5\plugins

set PATH=C:\Program Files\Git\bin;%PATH%

cmd.exe

Answer 3

对于Ubuntu用户，我尝试了一下，但没有成功：

pb_tool compile

同样绑定到安装python-qt5和Ubuntu 20.04找不到它，然后使用

sudo apt install pyqt5-dev-tool

然后pb_tool编译，它工作了。
