使用Inno Setup为Python创建Windows安装程序

如果您正在考虑创建一个安装程序（用于Windows），它将在启动（安装）我的应用程序之前自动安装所需的设置

那么下面的脚本将帮助您做到这一点...您需要在runsection和files部分中提及python可执行文件，就像该脚本中的winscp一样。

; Script generated by the Inno Setup Script Wizard.

#define MyAppName "My Program"
#define MyAppVersion "1.5"
#define MyAppPublisher "My Company, Inc."
#define MyAppURL "http://www.example.com/"
#define MyAppExeName "MyProg.exe"

[Setup]
; NOTE: The value of AppId uniquely identifies this application.
; Do not use the same AppId value in installers for other applications.
; (To generate a new GUID, click Tools | Generate GUID inside the IDE.)
AppId={{BD59E856-F194-4E05-A93B-89089F3E3E9D}
AppName={#MyAppName}
AppVersion={#MyAppVersion}

您可以使用以下方法查找是否已安装python

1.Direxists功能（在这里您可以检查程序文件中是否存在python目录）

2. filexists函数（通过它可以检查用户系统中是否存在python文件）

3.使用python注册表项名称（HKEY_LOCAL_MACHINE \ SOFTWARE \ Python）查询注册表。

然后，如果您得到的结果是肯定的，则进行应用程序安装，否则，为Windows安装python，然后运行应用程序。您需要在“文件”部分的帮助下为Windows安装程序打包python。您必须使用inno setup的[Code]部分才能使用上述功能。

请参阅pascal脚本：inno setup帮助文件中的支持功能。
