NSIS：如何基于选定的语言加载不同的许可证文件

Question

我试着用电子构建器制作NSIS安装程序。我需要根据用户根据选定的语言显示不同的许可证文件。

package.json

"devDependencies": {
    "electron": "22.0.1",
    "electron-builder": "^23.6.0"
  },

"build": {
    
    "directories": {
      "output": "out"
    },

    "win": {
      "target": "nsis",
      "icon": "images/logo.ico"
    },

    "nsis": {
      "oneClick": false,
      "deleteAppDataOnUninstall": true,
      "uninstallerIcon": "images/logo.ico",
      "installerIcon": "images/logo.ico",

      "displayLanguageSelector": true,
      "installerLanguages": ["en_US", "bg_BG"],
      "multiLanguageInstaller": true,

      "perMachine": true,
      "include": "build/preInstall.nsh"
    }
  }
}

Preinstall.nsh

!include MUI2.nsh
!insertmacro MUI_PAGE_WELCOME
!insertmacro MUI_PAGE_LICENSE $(translatedlicensefile)
!insertmacro MUI_PAGE_DIRECTORY
!insertmacro MUI_PAGE_INSTFILES
!insertmacro MUI_PAGE_FINISH

!insertmacro MUI_LANGUAGE English
LicenseLangString translatedlicensefile ${LANG_ENGLISH} "build/license/license_en.txt"
!insertmacro MUI_LANGUAGE Bulgarian
LicenseLangString translatedlicensefile ${LANG_BULGARIAN} "build/license/license_bg.txt"

发生此错误：

Error output:
LicenseLangString: open failed "build/license/license_en.txt"
Usage: LicenseLangString name lang_id|0 license_path
!include: error in script: "/Users/..../preInstall.nsh" on line 32
Error in script "<stdin>" on line 51 -- aborting creation process

线32是

LicenseLangString translatedlicensefile ${LANG_ENGLISH} "build/license/license_en.txt" 我尝试了许多示例，包括官方的示例，并想使用电子构建器弄乱了NSIS脚本的流程，但此时我无法包括任何修改。

提前感谢

i我找到了将许可证文件直接加载到NSIS代码中的解决方法。这不是一个好习惯，而是仍在寻找更好的解决方案。

Answer 1

Node_modules/app-builder-lib/out/targets/nsis/nsislicense.js

const licenseFiles = await license_1.getLicenseFiles(packager);
// --> workaround
let license_bg = {file: packager.projectDir + "/pages/license_bg.txt", lang:"bg", langWithRegion:"bg_BG", langName:"Bulgarian"};
let license_en = {file: packager.projectDir + "/pages/license_en.txt", lang:"en", langWithRegion:"en_US", langName:"English"};
licenseFiles.push(license_el);
licenseFiles.push(license_en);
// <-- workaround
// if (licenseFiles.length === 0) {
//     return;
// }

那是对我有用的。

I放置了

和

LICENSE_RU.RTF

to ./build文件夹（相对于Project root Directory） - 事实证明这很重要。并将它们添加到额外文件列表中，如下所示。

package.json

"build": {
  . . .
  "extraFiles": [
    "license_en.rtf",
    "license_ru.rtf"
  ],
  "nsis": {
    . . .
    "displayLanguageSelector": true,
    "installerLanguages": ["en_US", "ru_RU"],
    "multiLanguageInstaller": true
  }
}

根据

Electron-Builder的源代码，您可以使用.rtf，.txt和.html来使自动化起作用。 P.S：电子构建器VER。 25.1.8
