推荐答案
我猜你正在尝试使用 node.js 运行 electron.你的 package.json 是这样的吗?
I guess you are trying to run electron using node. Does your package.json look like this?
{ "scripts": { "start": "node main.js" } }
请改成这样运行电子应用
please change to run electron app like this
{ "scripts": { "start": "electron ." } }
它应该可以工作
注意:对于使用类似命令将电子安装到全局的人来说这是额外的
note: this is extra for somebody that install electron to global with command something like this
npm install -g electron
当你想在代码中使用电子时require(electron)你应该使用这个命令将全局路径链接到你的当前目录
when you want to use electron in the code require(electron) you should link the global path to your current directory by using this command
npm link electron
