为什么 npm install 会获取旧版本的包？

Question

我正在尝试运行这个命令：

npm install --save react-highlight-words@0.16.0

失败并显示此消息：

npm install --save react-highlight-words@0.16.0
(node:16708) ExperimentalWarning: The fs.promises API is experimental

但是查看此包的 github code：

  "peerDependencies": {
    "react": "^0.14.0 || ^15.0.0 || ^16.0.0-0 || ^17.0.0-0"
  }

它似乎支持 React v17（我有）

所以我不明白为什么 npm 不让我安装这个包？

Answer 1

您正在查看 package.json 的 master 版本，它实际上可能与 0.16.0 版本不对应。

没有 0.16.0 的标签，但您仍然可以通过...查看已发布版本的依赖项...

npm view react-highlight-words@0.16.0 peerDependencies

# { react: '^0.14.0 || ^15.0.0 || ^16.0.0-0' }

请注意 v0.16.0 是 over 3 years old。 NPM 上的当前版本是 0.17.0，这可能是你想要的

npm view react-highlight-words peerDependencies

# { react: '^0.14.0 || ^15.0.0 || ^16.0.0-0 || ^17.0.0-0' }

为什么 npm install 会获取旧版本的包？

Why does npm install fetch an old version of the package?

npm

npm-install
