FileNotFoundError:[WinError 2]

Question

我试图从https://pypi.org/project/pygmsh/执行以下代码

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)

我得到以下错误：

Traceback (most recent call last): File "C:/Users/200498/PycharmProjects/untitled/venv/test_builtin.py", line 30, in points, cells, point_data, cell_data, field_data =pygmsh.generate_mesh(geom) File "C:\ProgramData\Anaconda3\lib\site-packages\pygmsh\helpers.py", line 117, in generate_mesh gmsh_major_version = get_gmsh_major_version(gmsh_executable) File "C:\ProgramData\Anaconda3\lib\site-packages\pygmsh\helpers.py", line 81, in get_gmsh_major_version stderr=subprocess.STDOUT File "C:\ProgramData\Anaconda3\lib\subprocess.py", line 336, in check_output **kwargs).stdout File "C:\ProgramData\Anaconda3\lib\subprocess.py", line 403, in run with Popen(*popenargs, **kwargs) as process: File "C:\ProgramData\Anaconda3\lib\subprocess.py", line 709, in init restore_signals, start_new_session) File "C:\ProgramData\Anaconda3\lib\subprocess.py", line 997, in _execute_child startupinfo) FileNotFoundError: [WinError 2] The system cannot find the file specified: especificado

我该怎么解决呢？在

可能您使用的是Windows和“gmsh_path”变量助手.py在中设置为无，并且在中的“\u get_gmsh_exe（）”方法助手.py只设置为典型的MacOS路径gmsh.exe文件. 你必须设置gmsh.exe文件路径。在
