Pyinstaller打包QGIS独立应用

安装pyinstaller

管理员启动cmd，进入到C:\Program Files\QGIS 3.4\bin，执行命令(非稳定版为：python-qgis.bat)：

python-qgis-ltr.bat -m pip pyinstaller

示例代码

import sys
from qgis.core import QgsApplication
from qgis.gui import QgsMapCanvas

def init():
  a = QgsApplication([], True)
  QgsApplication.setPrefixPath('qgis', True)
  QgsApplication.initQgis()
  return a

def show_canvas(app):
  canvas = QgsMapCanvas()
  canvas.show()
  app.exec_()
app = init()
show_canvas(app)

运行示例

运行成功后会出现空白窗口

完成后进入dist文件夹中的test目录，目录结构如下：

注意：其中qgis文件夹就是示例代码中设置的路径：QgsApplication.setPrefixPath('qgis', True)

运行

双击test.exe运行
