Question

我正在尝试将npm软件包依赖项安装到我的angular应用程序中，并且出现此错误。有任何解决方法吗？

npm ERR! code E404
npm ERR! 404 Not Found: error-ex@^1.2.0

npm ERR!     C:\Users\Dilushi\AppData\Roaming\npm-cache\_logs\2020-02-12T13_07_17_602Z-debug.log

我将在此处附加我的package.json文件。

Answer 1

正如您在https://status.npmjs.org上所看到的那样，目前有4个软件包被关闭。

他们已经解决了该问题，但是我们需要等待CDN世界的传播。

请勿更新您的软件包或安装新软件包以解决此问题。

Answer 2

尝试使用此配置npm npm config set registry https://skimdb.npmjs.com/registry

Answer 3

现在应该可以使用了。他们已修复它。我已经尝试过并且可以工作了

Answer 4

有时您的其他软件包可能与您将要通过npm安装的软件包不兼容

卸载并重新安装最新的Node

具有最新的NPM版本

Answer 5

此问题可能还有另一个原因，请检查您的npm注册表配置是http://registry.npmjs.org/而不是http://registry.npmjs.org或https://registry.npmjs.org/

Answer 6

为了避免这个错误，你应该运行这个命令

<块引用>

npm init react-app my-app

有关详细信息，请查看此链接 npm error 404 not Found

Answer 7

我认为你触发了错误的命令，请检查命令的拼写 npx react-native run-android 然后它会起作用。

npm ERR！找不到404-GET https://registry.npmjs.org/error-ex
