Yet another reason: If your pre-build event references another projects bin path and you see this error when running msbuild, but not Visual Studio, then you have to manually arrange the projects in the *.sln file (with a text editor) so that the project you are targeting in the event is built before the event's project. In other words, msbuild uses the order that projects are listed in the *.sln file whereas VS uses knowledge of project dependencies. I had this happen when a tool that creates a database to be included in a wixproj was listed after the wixproj.

检查拼写。我试图调用一个可执行文件，但有名称拼写错误，它给了我退出与代码9009消息。

您需要确保已全局安装了grunt

当找不到signtool.exe本身时，我实际上得到了这个错误消息。为了解决这个问题，我将文件夹路径添加到path环境变量中，并重新启动Visual Studio。

在我的案例中，问题发生在我试图在命令行上为测试类库中的Post-build事件使用命令时。当你像这样使用引号时:

"$(SolutionDir)\packages\NUnit.Runners.2.6.2\tools\nunit" "$(TargetPath)" 

或者如果你使用控制台:

"$(SolutionDir)\packages\NUnit.Runners.2.6.2\tools\nunit-console" "$(TargetPath)"

这为我解决了问题。
