" cmd.exe的"无法运行。 [英] "cmd.exe" could not be run.
问题描述
昨天安全部门正在搞乱迈克菲设置，突然之间我无法构建我的解决方案。我有以下一个错误：
指定的任务可执行文件"cmd.exe"无法运行。 System.IO.IOException：无法创建临时文件。临时文件文件夹已满或其路径不正确。访问路径'C：\Users\hsimpson\AppData\Local\Temp\tmp77de4b0230e0494787ccfe80380a149a.exec.cmd'

我清理了Temp文件但没有帮助。 这就像是仍然存在权限错误。
任何想法？ 遇到此问题的其他人？
嗨含羞草，
欢迎来到MSDN论坛。
请检查
此主题 ，也许你可以从中得到一些帮助。
并且请确认您已获得当前用户帐户的"管理"权限。删除.vs，bin和obj文件夹（在
备份后之后），以管理员身份运行VS并重建解决方案。
此外，您还可以try命令： del / F / S / Q％TEMP％\ tmp * .tmp快速清理临时文件。根据问题，也许你可以从 C：\ WINDOWS \Temp 和
C：\ Users \ hsimpson \ AppData \ Local \Temp 。
希望以上所有有帮助。如果它有用或有帮助，请告诉我。
最好的问候

Yesterday security was messing around with McAfee settings and all of a sudden I could not build my solution. I had the following one error:
The specified task executable "cmd.exe" could not be run. System.IO.IOException: Failed to create a temporary file. Temporary files folder is full or its path is incorrect. Access to the path 'C:\Users\hsimpson\AppData\Local\Temp\tmp77de4b0230e0494787ccfe80380a149a.exec.cmd'

There was another file too created and it contained:

I cleaned up the Temp file and that didn't help. It's like there is still a permissions error.
Any Ideas? Anyone else running into this McAfee issue?
Hi Mimosa,
Welcome to MSDN forum.
Please check this thread, maybe you can get some help from it.
And please confirm that you've got the Administration permission with the current user account. Delete the .vs, bin and obj folder(after backup them), run VS as admin and rebuild the solution.
Also, you can try command: del /F /S /Q %TEMP%\tmp*.tmp to quickly cleanup the temp files. And according to the issue, maybe you can delete both temp files from C:\WINDOWS\Temp and C:\Users\hsimpson\AppData\Local\Temp.
Hope all above helps. If it's helpful or not, please let me know.
Best Regards
Lance
