Question

我是Python的新手，如果这是一个愚蠢的问题，敬请原谅。无论如何，尝试运行在PyCharm（Python IDE）上安装的软件包时出现此错误：

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

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

从我从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，就找不到如何将其导入virtualenv的正确安装指南。有人有经验吗？

我想更具体地讲，有什么方法可以查明它试图访问的路径并将gmsh粘贴到该目录中吗？

Answer 1

openbte\geometry.py似乎在运行gmsh.exe却没有任何路径：

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

这意味着它期望gmsh.exe中%PATH%的某个位置。因此，安装gmsh，并将带有gmsh.exe的目录添加到%PATH%。

将gmsh放入virtualenv
