python - 让 gmsh 进入 virtualenv

Question

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，当我尝试运行我在 PyCharm (Python IDE) 上安装的包时，我收到此错误:

Traceback (most recent call last):
  File "C:\Users\turtl\PycharmProjects\untitled\venv\Scripts\openbte-script.py", line 11, in <module>
    load_entry_point('openbte==0.9.24', 'console_scripts', 'openbte')()

    startupinfo)
FileNotFoundError: [WinError 2] The system cannot find the file specified

从我之前的问题中收集到的信息，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。有人有这方面的经验吗？

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

Answer 1

openbte\geometry.py 似乎在没有任何路径的情况下运行 gmsh.exe:

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

这意味着它需要 %PATH% 中的某个位置 gmsh.exe。因此，安装 gmsh 并将包含 gmsh.exe 的目录添加到 %PATH% 中。
