批处理文件:相对路径错误,从当前目录向上一级

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获取错误.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,我收到错误:

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仍然获取其当前路径.

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

我需要C:\ batch\path.我怎么能走这条路呢？它工作正常如果我给出绝对路径 -

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

Answer 1

您尝试使用目标%~1结构中的一个级别是创造性的并且语法完全无效.正确的语法就是这么简单 - 使用..\.

\不需要领先,因为%~dp0以a结尾\.

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