FileNotFoundError:[WinError 2] [英] FileNotFoundError: [WinError 2]

问题描述

我正在尝试从 https://pypi.org/project/pygmsh/

import pygmsh
import numpy as np
geom = pygmsh.built_in.Geometry()
# Draw a cross.
poly = geom.add_polygon([
 [ 0.0,  0.5, 0.0],
 [-0.1,  0.1, 0.0],
 [-0.5,  0.0, 0.0],
 [-0.1, -0.1, 0.0],
 [ 0.0, -0.5, 0.0],
 [ 0.1, -0.1, 0.0],
 [ 0.5,  0.0, 0.0],
 [ 0.1,  0.1, 0.0]
 ],
 lcar=0.05
 )
axis = [0, 0, 1]
geom.extrude(
 poly,
 translation_axis=axis,
 rotation_axis=axis,
 point_on_axis=[0, 0, 0],
 angle=2.0 / 6.0 * np.pi
 )
points, cells, point_data, cell_data, field_data =pygmsh.generate_mesh(geom)

我遇到以下错误:

我该如何解决?

推荐答案

可能您使用的是Windows，并且helpers.py中的"gmsh_path"变量设置为 None 和"_get_gmsh_exe()" "helpers.py中的方法"仅设置为gmsh.exe的典型MacOS路径.您必须设置实际的gmsh.exe路径.

Probably you're using Windows, and "gmsh_path" variable in helpers.py in set to None, and "_get_gmsh_exe()" method in helpers.py is only setted to typical MacOS path to gmsh.exe. You must set your actual gmsh.exe path.
