如何解决npm和cnpm无法卸载依赖的问题？

cnpm/npm 都无法卸载依赖。npm不能安装也不能卸载依赖。只能运行cnpm install. 环境node 10.16.3 npm 6.9.0 * 如果运行npm cache clean --force会报错 "image.png" (https://wmprod.oss-cn-shanghai.aliyuncs.com/images/20250121/42bf8a166c42039472c26fdb0124385e.png) *** * 如果运行cnpm cache clean --force报错 "image.png" (https://wmprod.oss-cn-shanghai.aliyuncs.com/images/20250121/efbed96c43b2cff8ed4ea3159ca5d460.png) * 如果cnpm uninstall xxx会报错 "image.png" (https://wmprod.oss-cn-shanghai.aliyuncs.com/images/20250121/5a16404812895956fa1057bcc75fba55.png)

在MongoDB中，简单场景是否适宜使用事务？

简单场景下使用mongoDB事务是否合适？有一个项目使用的是mongoDB作为存储数据库，其中用户充值购买VIP功能（逻辑很简单）打算使用mongoDB中的事务来实现，看官网文档的介绍说使用事务的性能并不好。那这样说在mongoDB中应该避免使用事务吗？（我是mongoDB新手，刚使用这种数据库）

electron实现区域录屏，我使用ffmpeg，有其他方法吗？

我用electron 实现了一个录屏软件，使用 desktopCapturer 可以录制全屏，但是我想局部或者区域录屏，就不太行，electronjs 好像不能使用 CropTarget 这个类，只能比较曲折的用ffmpeg实现的。大佬们，有什么优雅的方法吗？

Node项目中 CommonJs语法和ES6 Module的语法，两个不同语法的文件可以互相导入吗？

现象 1. 项目A：ESM 模块文件中导入 CommonJS 模块文件。运行项目没报错 «"https://stackblitz.com/edit/stackblitz-starters-> pescaa?file=p..."

加班使我熟睡

付费软件如何设计验证是否会员身份？

请问，付费软件的是否付费这功能是怎么设计/做的呢？我们知道，很多付费软件如果不付费是不能使用高级功能的。 "image.png" (https://wmprod.oss-cn-shanghai.aliyuncs.com/images/20241229/9bee019fe173440c2c2415d91ed6a77d.png) 请问下： 1. 是否有对应的付费验证的设计教程可以参考我们设计实现呢？ 2. [联网功能] 比如，这里非付费会员每天可以保存1篇文章，但是我保存第2篇文章的时候，一般是怎么进行验证的，是将自己的userid传输，每次保存时候调用后端API时候，后端都进行先验证再保存吗？ 3. [本地功能] 比如，功能在本地软件上，这样的验证是否会员的策略是直接获取API得到是否会员然后进行验证是否可以使用是吗？是否有更好的方法呢？总觉得这个方法不好一样，容易本地破解。
