Exiting application: lab解决方式
找了许久在这篇文章npm ERR! code: ‘EPERM’ (权限问题 errro permit)中找到解决办法。
进入C:Users{账户名}
删除该目录下的.npmrc文件即可
之后再通过命令安装插件，可以看到插件被成功安装。
好用的插件推荐
这篇博客jupyterlab 插件推荐提供了一些比较实用的插件和下载配置方法。
截止此文撰写时，除了jupyterlab-variableInspector这个插件外，其它均可正常安装。
jupyterlab-variableInspector安装失败，原作者的github上有人给出了解决方法。
下载本地vi.tar.gz文件，使用pip install vi.tar.gz安装即可。
该文件我也上传到了我的资源内，有需要的可以下载。
