Answer 1

我也有类似的问题。只需使用以下命令来更新您的 npm 版本：

npm install -g npm

Answer 2

这些警告来自您在 package.json 中使用的库。有两种类型的库：

1. 直接库：您直接列出它
2. 传递库：通过使用其他库来安装

那么你必须做什么：

运行

npm list --depth=3

（如果没有找到则增加深度） 并跟踪该库的来源，一旦找到它，您有 2 个选择：

1. 升级它，大多数情况下都有效
2. 删除它并使用另一个具有最新版本传递库的库

Answer 3

1. 奔跑

   npm ls package_name@version

   所以在你的情况下第一个包裹

   npm ls [email protected]

2. 您将获得其安装源。像这样的东西（例如）

    │ │   └─┬ [email protected]
    │ │     └─┬ [email protected]
    │ │       └─┬ [email protected]
    │ │         └── [email protected]
   

3. 所以，如果是直接安装，您可以简单地从https://www.npmjs.com找到更新的版本。直接在package.json中更新版本，删除node_modules文件夹，然后运行

   npm i

   。

4. 如果不是直接安装，可以尝试用类似的方式更新父包，看看是否包含所需包的更新版本。更新 package.json 中的父包版本后，如果它包含过时包的更新版本，您将不会在终端中收到错误消息。

这将解决错误消息。

我也找不到答案，你能解决这个错误吗？

尝试过 >npm ls typescript@* vu[电子邮件受保护] D:\Desktop\Vue 项目 ue-anime-db └──（空

Answer 5

尝试

npm 我-g

或

删除当前版本的节点并重新安装最新的稳定版本。

其中任何一个都应该有效。
