electron 打包，NSIS修改默认安装路径

我们用NSIS打包electron做的exe时，默认安装路径都是C盘，如果想要修改默认安装路径，就需要写个NSIS脚本来修改。

1.package.json的nsis里添加

"include": "build/script/installer.nsh"

2.新建文件installer.nsh

!macro preInit
    SetRegView 64
    WriteRegExpandStr HKLM "${INSTALL_REGISTRY_KEY}" InstallLocation "D:\Program Files\abc"
    WriteRegExpandStr HkCU "${INSTALL_REGISTRY_KEY}" InstallLocation "D:\Program Files\abc"
    SetRegView 32
    WriteRegExpandStr HKLM "${INSTALL_REGISTRY_KEY}" InstallLocation "D:\Program Files\abc"
    WriteRegExpandStr HkCU "${INSTALL_REGISTRY_KEY}" InstallLocation "D:\Program Files\abc"
!macroend
