Node_Modules 文件夹在“npm install”后消失

Question

每当我在新计算机上的项目上运行“npm install”命令时，都会出现一些奇怪的行为。安装命令完成后，我的 node_modules 文件夹就会消失。任何帮助表示赞赏！

这是日志：

PS C:\Dev\eth> npm i

您可能缓存了一个包，但校验和比较失败，您可以尝试：

$ cd <project_directory>
$ rm -rf package-lock.json npm-shrinkwrap.json node_modules
$ npm cache clean --force
$ npm cache verify
$ npm install

或者看这里：当我运行“npm install”时，它返回“ERR！” 代码 EINTEGRITY` (npm 5.3.0)

由于您正在使用 Crypto 构建某些内容，因此我会格外小心，并确保这实际上只是一个错误/误报，而不是未通过校验和的恶意包。后者的可能性非常低，但我会在这一步多加注意。
