【问题描述】：

我正在尝试从使用 pyinstaller 创建的可执行文件中使用 geopandas 库。但它会引发有关缺少 dll 文件的错误。我可以在作为 python 文件执行时运行脚本，但不能作为可执行文件运行。

这是我正在使用的脚本（名为 sample.py）：

import geopandas as gpd
print("Hello world")

这是我遇到的错误：

(venv) C:\Users\Windows 10\Desktop\py2exe\dist\sample>sample.exe

我执行了pyinstaller sample.py 来创建可执行文件。

【问题讨论】：

如果你能找到spatialindex_c.dll，也许在geopandas包的安装位置，你可以尝试手动把它放到dist/文件夹中。

标签： python pyinstaller geopandas

【解决方案1】：

您可以在 pyinstaller 命令中添加--collect-binaries rtree，如果
您正在使用pyinstaller 4.3 或更高版本。

spatial*.dlls 位于 rtree 包内：

|   core.py
|   exceptions.py
|   finder.py
|   index.py
|   __init__.py
|
\---lib
        spatialindex-64.dll
        spatialindex_c-64.dll

PyInstaller 将收集 dll 并将它们放入 dist/ 文件夹中。
