Answer 1

1. 在您的项目中创建 .npmrc 文件
2. 然后添加@foo:registry=https://gitlab.example.com/api/v4/projects/${CI_PROJECT_ID}/packages/npm/

Answer 2

我也遇到了同样的问题，以上都不适合我！

解决这个问题：

1. 删除package.json 和package-lock.json 文件

2. 然后在cmd中（进入boilerplate-express app的正确路径）然后使用：

   npm init -y
   

   它将创建一个新的package.json 文件，但在该文件中您必须检查"main" 属性，将"main" 属性设置为server.js

3. 在server.js 文件中，他们使用var bGround = require('fcc-express-bground'); 代替var bGround = require('fcc-express-background'); 并保存文件（因为在npmjs.com 中没有fcc-express-bground 等模块，但fcc-express-background 模块可用于样板应用程序）

4. 然后安装那些被询问的包模块。

Answer 3

我认为您触发了错误的命令，请检查命令的拼写 npx react-native run-android 然后就可以了。

Answer 4

为了避免这个错误，你应该运行这个命令

npm init react-app my-app

Answer 5

这个问题可能还有其他原因，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

正如您在 https://status.npmjs.org 上看到的那样，目前有 4 个包被关闭。

他们已经解决了这个问题，但我们需要等待 CDN 世界传播。

不要更新您的软件包或安装新软件包来解决此问题。

Answer 7

有时您的其他软件包可能与您要通过 npm 安装的软件包不兼容

卸载并重新安装最新的 Node

拥有最新的 NPM 版本

Answer 8

现在应该可以了。他们已经修好了。我现在已经尝试过了，并且可以正常工作

Answer 9

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