如何在Windows上安装pygalmesh (依赖于本征)？
提问于 2020-04-28 03:15:03
编辑:对于那些感兴趣的人，创建者目前正在开发这个这里。
我正在尝试使用吡咯烷酮安装pip install pygalmesh，这取决于本征。我已经下载了Eigen，但是pip安装程序并不“知道”这一点。它返回以下错误消息：
ERROR: Could not build wheels for pygalmesh which use PEP 517 and cannot be installed directly更具体而言：
fatal error C1083: Cannot open include file: 'Eigen/Dense':pygalmesh的github有一个setup.py文件，我可以编辑，但是我不知道如何安装pygalmesh。还带着皮普吗？
是否有我可以编辑的setup.py文件，以便安装程序知道特征/密度在哪里？由于我有一台Windows，我至少认为/需要改为\。但是我找不到要编辑的setup.py。
我在网站的其他地方找到了关于这个问题的对话，也在这里上找到了。我不知道如何实现这些帖子中提到的内容。我也尝试过通过conda安装艾根，比如这里。这也不起作用。

此解决方案适用于Windows 10，安装了python3.8和VisualStudioCommunity2019。
- 安装依赖关系：
gmp、mpfr、eigen3和cgal。我推荐用于libs构建和安装的vcpkg，如下所述。您还可以以自己的方式分别安装和构建这些依赖关系，而不需要vcpkg。 1.1。安装vcpkg(https://vcpkg.io/en/getting-started.html)。 1.2。安装对x64静态配置的依赖关系： 安装gmp:x64 windows静态vcpkg安装mpfr:x64 windows静态vcpkg安装特征3:x64 windows静态vcpkg安装cgal:x64 windows - 克隆
pygalmesh源： git克隆https://github.com/nschloe/pygalmesh.git - 将
library_dirs=["C:/path/to/vcpkg/installed/x64-windows-static/lib"]添加到pygalmesh/setup.py(请参阅post下面的修改setup.py，也可以检查备选解决方案)。不要忘记插入您自己的vcpkg/path/to/vcpkg.位置，而不是my 位置 - 构建和安装
pygalmesh： cd吡咯烷酮集EIGEN_INCLUDE_DIR=C:/path/to/vcpkg/installed/x64-windows-static/include pip安装。 - 确保安装了
pygalmesh： python >>>导入pygalmesh
改性setup.py
import os
from pybind11.setup_helpers import Pybind11Extension, build_ext
from setuptools import setup
# https://github.com/pybind/python_example/
ext_modules = [
Pybind11Extension(
"_pygalmesh",
# Sort input source files to ensure bit-for-bit reproducible builds
# (https://github.com/pybind/python_example/pull/53)
sorted(
[
"src/generate.cpp",
"src/generate_2d.cpp",
"src/generate_from_inr.cpp",
"src/generate_from_off.cpp",
"src/generate_periodic.cpp",
"src/generate_surface_mesh.cpp",
"src/remesh_surface.cpp",
"src/pybind11.cpp",
]
),
include_dirs=[os.environ.get("EIGEN_INCLUDE_DIR", "/usr/include/eigen3/")],
# no CGAL libraries necessary from CGAL 5.0 onwards
libraries=["gmp", "mpfr"],
# !!! ADD YOUR PATH HERE !!!
library_dirs=["C:/D/Apps/vcpkg/installed/x64-windows-static/lib"]
)
]
if __name__ == "__main__":
setup(
cmdclass={"build_ext": build_ext},
ext_modules=ext_modules,
zip_safe=False,
)替代解
实际上，pip有指向库路径的命令行参数(--global-option=build_ext、--include-path、--library-path 见pip文档和这个职位)，并且潜在的安装可能是一对行(在安装C++ libs的步骤1之后)：
set EIGEN_INCLUDE_DIR=C:/path/to/vcpkg/installed/x64-windows-static/include
pip install --global-option=build_ext --install-option="--include-path=C:\path\to\vcpkg\installed\x64-windows-static\include" --global-option="--library-path=C:\path\to\vcpkg\installed\x64-windows-static\lib" pygalmesh但。由于某些原因(可能只是我的系统配置特性，或者是setuptools==58.1.0版本特定的“功能”)，在构建包时，setuptools不向MSVC link.exe的/LIBPATH:键添加--library-path参数，这会导致LNK错误。
