本文介绍了Electron 无法正确安装，请删除 node_modules/并尝试重新安装的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我正在尝试使用 webpack + react + electron，当我在 CLI 中输入electron"时.它给了我这个错误:
我删除了 node_modules 并一遍又一遍地重新安装了所有模块大约 6 次，显然删除 node_modules 并安装不是解决方案，所以我需要社区的帮助来查找此错误.

确保删除 node_modules 文件夹并运行 yarn cache clean 或 npm cache verify 以确保缓存已从损坏问题中修复.
现在再次安装您的依赖项 npm install 或 yarn 一切都应该正常工作.
I am trying to use webpack + react + electron, and when I type in the CLI "electron ." it gives me this error:
I deleted node_modules and re-installed all the modules over and over like about 6 times, obviously deleting node_modules and installing isn't a solution, so I need the community's help on finding this error.

解决方案 This usually happens due to bad network so the dependencies aren't downloaded and installed correctly.
Make sure to delete node_modules folder and run yarn cache clean or npm cache verify to make sure the cache is healed from corruption issues.
Now install your dependencies again npm install or yarn and everything should work properly.
