求助：RuntimeError: Could not locate a supported Microsoft Visual C++ installation

[xiwwix]

运行app.py时遇到了以下问题： (nerfstream) D:\lipkumetahuman-stream\metahuman-stream>python app.py Traceback (most recent call last): File "D:\lipkumetahuman-stream\metahuman-stream\ernerf\raymarching\raymarching.py", line 10, in import _raymarching_face as _backend ModuleNotFoundError: No module named '_raymarching_face'

During handling of the above exception, another exception occurred:

Traceback (most recent call last): File "D:\lipkumetahuman-stream\metahuman-stream\app.py", line 332, in from ernerf.nerf_triplane.network import NeRFNetwork File "D:\lipkumetahuman-stream\metahuman-stream\ernerf\nerf_triplane\network.py", line 6, in from .renderer import NeRFRenderer File "D:\lipkumetahuman-stream\metahuman-stream\ernerf\nerf_triplane\renderer.py", line 10, in from .. import raymarching File "D:\lipkumetahuman-stream\metahuman-stream\ernerf\raymarching_init_.py", line 1, in from .raymarching import * File "D:\lipkumetahuman-stream\metahuman-stream\ernerf\raymarching\raymarching.py", line 12, in from .backend import _backend File "D:\lipkumetahuman-stream\metahuman-stream\ernerf\raymarching\backend.py", line 28, in raise RuntimeError("Could not locate a supported Microsoft Visual C++ installation") RuntimeError: Could not locate a supported Microsoft Visual C++ installation

安装的VS是2022社区版，已按照网络教程添加了系统变量，问题仍然存在，希望能得到帮助，谢谢😭！

您好，问题解决了么？

您好，问题解决了么？ 可以先试试把ernerf下面的几个文件夹里有的setup.py都先运行一遍python setup.py install

这个问题的正确解法是在整个工程中搜索find_cl_path():然后找下你的H:\Program Files (x86)\Microsoft Visual Studio\2022\BuildTools\VC\Tools在哪个位置，比如我的找到是在H盘，所以我会把 # find cl.exe def find_cl_path(): import glob for edition in ["Enterprise", "Professional", "BuildTools", "Community"]: paths = sorted(glob.glob(r"C:\Program Files (x86)\Microsoft Visual Studio\\%s\VC\Tools\MSVC\\bin\Hostx64\x64" % edition), reverse=True) if paths: return paths[0] 中的 paths = sorted(glob.glob(r"C:\Program Files (x86)\Microsoft Visual Studio\\%s\VC\Tools\MSVC\\bin\Hostx64\x64" % edition), reverse=True) 替换为 paths = sorted(glob.glob(r"H:\Program Files (x86)\Microsoft Visual Studio\\%s\VC\Tools\MSVC\\bin\Hostx64\x64" % edition), reverse=True) 问题就解决了

首先visual studio 2022已经不存在C:\Program Files (x86)\Microsoft Visual Studio\%s\VC\Tools\MSVC\bin\Hostx64\x64，取而代之的是C:\Program Files\Microsoft Visual Studio\%s\VC\Tools\MSVC\bin\Hostx64\x64，但就算我修改了这个地方依然有这个错误出现。

我是这样解决的，我出现这个，是因为visual studio的安装目录不是在program files (x86)下 文件为ernerf/raymarching/backend.py
