让gmsh进入虚拟世界

Question

我对Python非常陌生，如果这是一个愚蠢的问题，我很抱歉。总之，我在尝试运行我安装在PyCharm（Python IDE）上的包时遇到了这个错误：

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')()

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

从我以前的问题中收集到的信息来看，这似乎是因为我的virtualenv中没有gmsh。既然我已经下载了gmsh，我就找不到一个合适的安装指南来指导如何将它安装到virtualenv中。有人有这方面的经验吗？你知道吗

我想更具体地说，有没有一种方法可以确定它试图访问的路径并将gmsh粘贴到该目录中？你知道吗

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'])

这意味着它期望gmsh.exe在%PATH%的某个地方。所以安装gmsh，并将带有gmsh.exe的目录添加到%PATH%。你知道吗
