[WinError 5] Access Denied: 'D:\\V-ExpressOutput-temp'

[WebKing2024]

我在“V-Express Sampler”节点遇到了拒绝访问错误，提示无法访问“D:\V-ExpressOutput-temp”文件夹，然后我在相应目录新建了“D:\V-ExpressOutput-temp”文件夹，问题依旧没有解决，完整的报错信息和截图如下：

I encountered an access denied error in the "V-Express Sampler" node, which said that the "D:\V-ExpressOutput-temp" folder could not be accessed. I then created a new "D:\V-ExpressOutput-temp" folder in the corresponding directory, but the issues was still not solved. The complete error message and screenshots are as follows:

The corresponding video length is 137. [ERROR:0@13898.964] global cap.cpp:597 cv::VideoWriter::open VIDEOIO(CV_IMAGES): raised OpenCV exception:

可能是你没有用管理员权限打开comfyui，所以才会没有权限删除文件夹。你试试用管理员权限运行comfyui。

感谢您的反馈，我用的是秋叶整合包，用管理员权限启动后，依然报这个错误，以下是新的报错信息：

!!! Exception during processing!!!

备注：我明天试试用原生ComfyUI更新包是否会出现这个问题。

或者你可以把对应的这一行代码注释掉，这一行原本是为了删掉生成过程的中间结果，不删也是可以的。 E:\ComfyUI-aki-v1.2\custom_nodes\ComfyUI-V-Express\src\pipelines\utils.py
91行
os.remove(temp_output_path) -> # os.remove(temp_output_path)

我注释掉这行代码，节点可以顺利通过并执行完毕，但视频预览下方的控件显示异常，点击无法播放视频，我又查看了未删除的output_temp目录和output目录下均没有任何视频文件，还有哪些可能会导致这个问题呢？

我刚注意到更新日志： [2024/06/15] 🔥 We have optimized memory usage, now supporting the generation of longer videos. 我记得下载的这个代码压缩包是15日之前的版本，我刚更新了最新代码，明天再执行一遍工作流查看最新结果。

没想到代码执行的如此之快，我得到了结果，并且我对比原代码，发现是更改了output_path参数时，没有输入文件名引起的异常。感谢开发团队的开源分享！

I didn't expect the code to execute so quickly. I got the result and compared it with the original code. I found that the exception was caused by not inputting the file name when the output_path parameter was changed. Thanks to the development team for sharing the open source!

是的，我将关闭这个问题，希望对后来者有所帮助。 Yes, I will close this question in the hope that it helps someone who comes later.
