“意外地”删除了node_modules文件夹

意外地删除了node_modules文件夹是指在开发过程中,由于一些意外情况导致了项目中的node_modules文件夹被删除或丢失。node_modules文件夹是用来存放项目所依赖的第三方模块的文件夹,通常由包管理工具(如npm)自动生成和维护。

这种情况可能会导致项目无法正常运行,因为缺少了必要的依赖模块。解决这个问题的方法有以下几种:

  1. 重新安装依赖:可以通过在项目根目录下执行命令npm installyarn install来重新安装项目所需的依赖模块。这会根据项目的package.json文件中的依赖配置,自动下载并安装所需的模块到node_modules文件夹中。
  2. 使用版本控制工具恢复:如果项目使用了版本控制工具(如Git),并且在删除node_modules文件夹之前进行了提交,可以通过版本控制工具的恢复功能将node_modules文件夹还原到之前的状态。
  3. 使用缓存恢复:如果之前已经执行过npm installyarn install命令,并且缓存中还有依赖模块的备份,可以尝试使用缓存来恢复node_modules文件夹。具体操作可以参考npm或yarn的文档。
  4. 手动安装依赖:如果以上方法都无法解决问题,可以尝试手动安装项目所需的依赖模块。首先需要查看项目的package.json文件,找到dependencies和devDependencies字段中列出的依赖模块,然后使用npm或yarn命令手动安装这些模块。

需要注意的是,删除node_modules文件夹后重新安装依赖模块可能会花费一些时间,特别是对于大型项目或依赖较多的项目。此外,为了避免意外删除node_modules文件夹,建议在使用版本控制工具时将其添加到忽略列表中,或者定期备份整个项目文件夹。

关于 npm 和 yarn 总结一些细节

Searches the local package tree and attempts to simplify the overall structure by moving dependencies further up the tree, where they can be more effectively shared by multiple dependent packages. For example, consider this dependency graph: a +-- b <-- depends on c@1.0.x | `-- c@1.0.3 `-- d <-- depends on c@~1.0.9 `-- c@1.0.10 In this case, npm dedupe will transform the tree to: a +-- b +-- d `-- c@1.0.10 Because of the hierarchical nature of node's module lookup, b and d will both get their dependency met by the single c package at the root level of the tree. 复制代码 // npm7 以后微调 // 在保持上述原则的基础上,升级了如下细微的规则: In some cases, you may have a dependency graph like this: a +-- b <-- depends on c@1.0.x +-- c@1.0.3 `-- d <-- depends on c@1.x `-- c@1.9.9 During the installation process, the c@1.0.3 dependency for b was placed in the root of the tree. Though d's dependency on c@1.x could have been satisfied by c@1.0.3, the newer c@1.9.0 dependency was used, because npm favors updates by default, even when doing so causes duplication. Running npm dedupe will cause npm to note the duplication and re-evaluate, deleting the nested c module, because the one in the root is sufficient. To prefer deduplication over novelty during the installation process, run npm install --prefer-dedupe or npm config set prefer-dedupe true. Arguments are ignored. Dedupe always acts on the entire tree. Note that this operation transforms the dependency tree, but will never result in new modules being installed. Using npm find-dupes will run the command in --dry-run mode. Note: npm dedupe will never update the semver values of direct dependencies in your project package.json, if you want to update values in package.json you can run: npm update --save instead.During the installation process, the c@1.0.3 dependency for b was placed in the root of the tree. Though d's dependency on c@1.x could have been satisfied by c@1.0.3
