我已经用nvm安装了nodejs，目前在Ubuntu 18.04上使用版本11.5.0
我只是想开始学习用电子编程，所以我使用了code example on GitHub，在运行npm start后出现了这个错误：
> electron-quick-start@1.0.0 start /home/alireza/extra/projects/vm/electron-quick-start
> electron .
sh: 1: electron: Permission denied
npm ERR! code ELIFECYCLE
npm ERR! errno 126
npm ERR! electron-quick-start@1.0.0 start: `electron .`
npm ERR! Exit status 126
npm ERR!
npm ERR! Failed at the electron-quick-start@1.0.0 start script.
npm ERR! This is probably not a problem with npm. There is likely additional logging output above.
npm ERR! A complete log of this run can be found in:

所以日志看起来像这样（很长的日志文件很抱歉）：

所以我被困在这里，尝试了很多事情。从一次又一次地删除rm -rf node-modules和npm install的node_modules到更改和检查对node_modules等的访问权限。
您是否还有此问题，或者您知道如何解决此问题？
