windows - 批处理文件：相对路径错误，从当前目录上一级

Question

我是批处理脚本编程的新手。如果我给出相对路径，则在执行批处理文件时会出错。我有以下文件夹结构

Script folder - C:\batch\script\ServiceRegister.bat
Bin path - C:\batch\bin\ERecruitGenerateReportsWindowsService.exe

ServiceRegister.bat 批处理文件 –

%windir%\Microsoft.NET\Framework\v4.0.30319\InstallUtil.exe %~dp0%~1\bin\ERecruitGenerateReportsWindowsService.exe

当我执行 ServiceRegister.bat 文件时，出现错误：

Exception occurred while initializing the installation:
System.IO.FileNotFoundException: Could not load file or assembly 'file:///C:\batch\script\bin\ERecruitGenerateReportsWindowsService.exe' or one of its dependencies. The system cannot find the file specified.

我正在使用“%~dp0%~1”在目录中向上移动一级，但它仍然获得其当前路径。

%~dp0%~1 - C:\batch\script\  

我需要 C:\batch\ 路径。我怎样才能得到这条路？如果我给出绝对路径，它工作正常 -

%windir%\Microsoft.NET\Framework\v4.0.30319\InstallUtil.exe C:\batch\bin\ERecruitGenerateReportsWindowsService.exe

Answer 1

Your attempt to use %~1 to go up one level in the directory structure is inventive and totally invalid syntax. The proper syntax is just as simple - use ..\.

A leading \ is not required because %~dp0 ends with a \.

%windir%\Microsoft.NET\Framework\v4.0.30319\InstallUtil.exe %~dp0..\bin\ERecruitGenerateReportsWindowsService.exe
