It seems dependency error means that particular Module is missing when it's running.似乎依赖错误意味着特定模块在运行时丢失。
Run npm ls or yarn list will print to stdout all the versions of packages that are installed, as well as their dependencies, in a tree-structure.运行npm ls or yarn list将以树形结构将已安装包的所有版本及其依赖项打印到标准输出。 Then search for that particulate packages are listed or not.然后搜索是否列出了颗粒包。 Run npm ls jspdf or yarn list jspdf then you can see its list of dependencies in tree-structure.运行npm ls jspdf or yarn list jspdf然后你可以在树结构中看到它的依赖列表。
Please check your node version is updated or not ?请检查您的node版本是否更新？ If not then update first.如果没有，请先更新。
Quick & Dirty way: delete package.lock or yarn.lock file and delete .node_modules folders And Then run npm install or yarn to install again. Quick & Dirty 方法：删除package.lock or yarn.lock文件并删除.node_modules文件夹，然后运行npm install or yarn再次安装。 Look at console while you installing and make sure there are no error in the installing process.安装时查看控制台，确保安装过程中没有错误。 If you saw error you better look that massages also.如果你看到错误，你最好也看看按摩。
