Electron Build 打包后如果安装在CProgram Files目录的问题

Electron Build 打包后如果安装在C:Program Files目录的问题

Electron Build 打包后如果安装在C:Program Files目录,这时候如果要写入文件你会发现会出现

Uncaught Error: EPERM: operation not permitted, open

经过测试 只要是默认C:Program Filesxxx目录好像都不行，那怎么办呢，既然这个目录不行，那就修改build的

默认配置不就行

修改默认安装路径

如何修改，参考官网

https://www.electron.build/configuration/nsis#custom-nsis-script

How do change the default installation directory to custom?

It is very specific requirement. Do not do if you are not sure. Add custom macro:

!macro preInit
  SetRegView 64
  WriteRegExpandStr HKLM "${INSTALL_REGISTRY_KEY}" InstallLocation "C:MyApp"
  WriteRegExpandStr HKCU "${INSTALL_REGISTRY_KEY}" InstallLocation "C:MyApp"
  SetRegView 32
  WriteRegExpandStr HKLM "${INSTALL_REGISTRY_KEY}" InstallLocation "C:MyApp"
  WriteRegExpandStr HKCU "${INSTALL_REGISTRY_KEY}" InstallLocation "C:MyApp"
!macroend

上面就是说在niss脚本中修改即可

如

;修改默认安装路径
!macro preInit
    SetRegView 64
    WriteRegExpandStr HKLM "${INSTALL_REGISTRY_KEY}" InstallLocation "C:makalo-cnblog-tool"
    WriteRegExpandStr HKCU "${INSTALL_REGISTRY_KEY}" InstallLocation "C:makalo-cnblog-tool"
    SetRegView 32
    WriteRegExpandStr HKLM "${INSTALL_REGISTRY_KEY}" InstallLocation "C:makalo-cnblog-tool"
    WriteRegExpandStr HKCU "${INSTALL_REGISTRY_KEY}" InstallLocation "C:makalo-cnblog-tool"
!macroend
