NSIS变量在定义变量中不允许有空格

NSIS变量在下面声明的变量中不允许有空格

 **define POSTGRESQL_INSTALLATION_DIRECTORY "C:\Program Files\Postgre SQL\9.3"**

如果我定义不带空格的变量（如：

[INFO] [MAKENSIS] DetailPrint expects 1 parameters, got 2.
[INFO] [MAKENSIS] Usage: DetailPrint message
[ERROR] Failed to execute goal org.codehaus.mojo:nsis-maven-plugin:1.0-SNAPSHOT:compile (64bit_REACH) on project dsr.installer: Execution of makensis compiler failed. See output above for details. -> [Help 1]

但是我想要声明变量之间的空间，比如

 `**define POSTGRESQL_INSTALLATION_DIRECTORY "C:\ProgramFiles\PostgreSQL\9.3"**`

因此，请让我知道如何执行此定义的变量。

编译器正在告诉您问题所在，

DetailPrint

指令使用1个参数，当带空格的字符串没有正确引用时，它将被解释为多个参数

`**define POSTGRESQL_INSTALLATION_DIRECTORY "C:\Program Files\Postgre SQL\9.3"**` 

---

你问的有点不清楚。当我在代码定义POSTGRESQL\u安装目录“C:\Program Files\POSTGRESQL\9.3”中添加变量时，我得到了编译失败消息。请告诉我如何执行此变量。您所说的是定义，而不是变量…您应该使用“$ProgramFiles\…”而不是硬代码“C:\ProgramFiles\…”

!define POSTGRESQL_INSTALLATION_DIRECTORY "C:\Program Files\PostgreSQL\9.3"

Section
;DetailPrint ${POSTGRESQL_INSTALLATION_DIRECTORY} ; This will not work because the string is not quoted
DetailPrint "${POSTGRESQL_INSTALLATION_DIRECTORY}"
DetailPrint '${POSTGRESQL_INSTALLATION_DIRECTORY}'
DetailPrint "Hello ${POSTGRESQL_INSTALLATION_DIRECTORY} World"
DetailPrint 'Hello "${POSTGRESQL_INSTALLATION_DIRECTORY}" World'
DetailPrint "Hello $\"${POSTGRESQL_INSTALLATION_DIRECTORY}$\" World"
