如何在Inno Setup中使用空格处理路径?

问题描述：

在使用Inno Setup安装程序时，我想允许路径带有空格(例如，程序文件).但是带有空格的路径会使我的已安装服务崩溃.

I want to allow paths with spaces (for example program files) when installing my program with Inno Setup. However paths with spaces let my installed service crash.

Inno Setup文件如下:

The Inno Setup file looks like this:

[Setup]
AppName=Demo
DefaultDirName={pf}\demo

[Files]
Source: "bin\nssm.exe"; DestDir: "{app}"
Source: "bin\jdk1.8.0_152\jre\*"; DestDir: "{app}\jre"; Flags: recursesubdirs
Source: "build\libs\demo.jar"; DestDir: "{app}"

[Run]
Filename: "{app}\nssm.exe"; \
    Parameters: "install demo ""{app}\jre\bin\java.exe"" -jar ""{app}\demo.jar"""
Filename: "{app}\nssm.exe"; Parameters: "start demo"

"nssm.exe"；是将Java应用程序作为Windows服务执行的服务包装器.

"nssm.exe" is a service wrapper to execute a java application as a windows service.

关键部分是这一行:

Filename: "{app}\nssm.exe"; \
     Parameters: "install demo ""{app}\jre\bin\java.exe"" -jar ""{app}\demo.jar"""

根据此问题/答案中的建议，我试图使用双双引号，但这无济于事，该服务仍在崩溃.如果我将 DefaultDirName 更改为没有空格的路径，那么一切都会按预期进行.

As suggested in this question/answer, I tried to use double double quotes, but this doesn't help, the service is still crashing. If I change DefaultDirName to a path without spaces everything works as expected.

DefaultDirName=c:\demo

我该如何处理带空格的路径?

How do I have to handle paths with spaces?

答

问题是Inno Setup和nssm的组合，它们都在转义双引号和双引号.这使得必须使用多个双引号.

The problem was the combination of Inno Setup and nssm, which both are escaping double quotes with double quotes. That makes multiple double quotes necessary.

解决方案:

Filename: "{app}\nssm.exe"; Parameters: "install demo ""{app}\jre\bin\java.exe"" -jar """"""{app}\demo.jar"""""""

请参见 nssm文档报价问题"部分.

See nssm documentation section "Quoting issues".
