我对Python StupTooSoT和Dist.No.i很陌生,我无法得到一个C++包装模块来导入,以便我可以使用这些函数。p>
pip安装后,编译后的.so文件将显示在installed-files.txt中,但导入包装器时不会显示

我试图使用virtualenv来隔离项目中运行所需的模块
以下是文件结构:
.
|-- CMakeLists.txt
|-- README.md
|-- bgtfs_py_lib
| |-- __init__.py
| |-- bgtfs_handler
|-- cpp
| |-- BgtfsFeedHandler.cpp

`-- test_functions.py
bgtfs\u py\u库中的init.py文件如下所示。包装器的功能正在公开
import bgtfs_py_lib_wrapper as _bgtfs_py_lib
from bgtfs_py_lib.bgtfs_handler.bgtfs_handler import BgtfsHandler
在另一个项目中,它是使用git+ssh和egg安装的pip
git+ssh://git@github.com/path/to/project.git@build/production/setup#egg=bgtfs_py_lib
当在pyCharm中Ictrl+space时,将找到包装器模块并显示类。
该模块位于二进制骨架目录中,但是
将bgtfs_py_lib包装器作为_bgtfs_py_lib导入根本不起作用,并引发以下异常:ModuleNotFoundError: No module named 'bgtfs_py_lib_wrapper'
有人能帮我弄清楚如何正确构建C++/Pybind11模块,并在安装了virtualenv的pip包中使用它们吗
我终于解决了
结果表明需要更改CMakeLists.txt,因为cmake_参数和build_参数之间不一致。因此,CMakeList.txt文件现在如下所示:
CMakeLists.txt
setup.py文件现在是:
setup.py
扩展文件不会输出到bgtfs_py_lib目录,而是输出到虚拟环境,需要项目本身
向Sergei大声呼喊,寻求帮助解决问题
