让 gmsh 进入 virtualenv

问题描述

我对 Python 非常陌生，如果这是一个愚蠢的问题，我很抱歉.无论如何，我在尝试运行安装在 PyCharm(Python IDE)上的包时遇到此错误:

I'm extremely new to Python, so sorry if this is a stupid question. Anyways, I'm getting this error when trying to run a package I installed on PyCharm (Python IDE):

Traceback (most recent call last):
  File "C:\Users\turtl\PycharmProjects\untitled\venv\Scripts\openbte-script.py", line 11, in <module>

从我从以前的问题中收集的信息来看，这似乎是因为我的 virtualenv 中没有 gmsh.现在我已经下载了 gmsh，但我找不到有关如何将其放入 virtualenv 的正确安装指南.有没有人有这方面的经验?

From what I've gathered from previous questions, it seems this is because I don't have gmsh in my virtualenv. Now that I've downloaded gmsh, I can't find a proper installation guide on how to get it into the virtualenv. Does anyone have experience with this?

我想更具体地说，有没有办法可以查明它试图访问的路径并将 gmsh 粘贴到该目录中?

I guess more specifically, is there a way I can pinpoint the path that it's trying to access and just paste gmsh into that directory?

推荐答案

openbte\geometry.py 似乎运行 gmsh.exe 没有任何路径:

openbte\geometry.py seems to run gmsh.exe without any path:

a=subprocess.check_output(['gmsh','-' + str(self.dim),'mesh.geo','-o','mesh.msh'])

这意味着它期望 gmsh.exe 位于 %PATH% 的某处.所以安装 gmsh 并将带有 gmsh.exe 的目录添加到 %PATH% 中.

Which means it expects gmsh.exe somewhere in the %PATH%. So install gmsh and add the directory with gmsh.exe to the %PATH%.
