Found my answer: The command had a line break between the source and destination strings. So, Visual Sudio was treating it as two commands. Eliminating the line break solved the problem.
找到我的答案：该命令在源字符串和目标字符串之间有一个换行符。因此，Visual Sudio 将其视为两个命令。消除换行符解决了问题。

Your xcopycommand failed for some reason.
xcopy由于某种原因，您的命令失败。
I would guess that either the DLL file doesn't exist (eg, the build failed) or the target path doesn't exist.
我猜想要么 DLL 文件不存在（例如，构建失败），要么目标路径不存在。
Run the same command line in a command prompt and see what error it prints.
在命令提示符下运行相同的命令行并查看它打印的错误。

I encounted this error on the TeamCity build server. I finally resolved it after checking the build log and found:
我在 TeamCity 构建服务器上遇到了这个错误。我在检查构建日志后终于解决了它，发现：
"'xcopy' is not recognized as an internal or external command."
“'xcopy' 未被识别为内部或外部命令。”
I then changed my statement to:
然后我将我的陈述改为：
C:\Windows\System32\xcopy"$(ProjectDir)config\Web.config.$(ConfigurationName)" "$(ProjectDir)Web.config" /Y/R
C:\Windows\System32\xcopy"$(ProjectDir)config\Web.config.$(ConfigurationName)" "$(ProjectDir)Web.config" /Y/R

This error can occur if your system PATH environment variable has been set incorrectly. The path should contain (at the very least)
如果您的系统 PATH 环境变量设置不正确，则会发生此错误。路径应该包含（至少）
%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;
on modern versions of Windows (see https://superuser.com/questions/124239/what-is-the-default-path-environment-variable-setting-on-fresh-install-of-window). I have just found my system PATH had been set to
在现代版本的 Windows 上（参见https://superuser.com/questions/124239/what-is-the-default-path-environment-variable-setting-on-fresh-install-of-window）。我刚刚发现我的系统 PATH 已设置为
C:\Program Files (x86)\Bad Vendor\Buggy Program;
by an msi installer that obviously has issues.
由显然有问题的 msi 安装程序。
If you don't know how to edit the PATH via the System Properties dialog, check out this link : http://support.microsoft.com/kb/310519- it's basically the same in Windows 7 & 8 as it is in XP.
如果您不知道如何通过“系统属性”对话框编辑 PATH，请查看此链接：http: //support.microsoft.com/kb/310519- 在 Windows 7 和 8 中与在 XP 中基本相同.
Finally, it's worth noting that a lot of programs don't notice if you update the PATH while they are running, so closing down and re-opeing programs like Visual Studio or command prompt windows will be required for the repaired path to take effect.
最后，值得注意的是，如果您在运行时更新 PATH，许多程序不会注意到，因此需要关闭并重新打开 Visual Studio 或命令提示符窗口等程序，修复后的路径才能生效。

Mostly related to path C\Program files...\some.exe. It should be "C\Program files...\some.exe"
主要与路径 C\Program files...\some.exe 相关。它应该是“C\Program files...\some.exe”
