node.js – 在公司防火墙后面使用create-react-app

通过设置代理,可以使用create-react-app在公司防火墙后面工作.

我已经在npm和yarn上设置了代理,但这是我在尝试创建 – react-app my-app时看到的：

Creating a new React app in F:\react\my-app.

Installing packages. This might take a couple of minutes.
Installing react,react-dom,and react-scripts...

You appear to be offline.
Falling back to the local Yarn cache.

yarn add v0.23.4
info No lockfile found.
[1/4] Resolving packages...
error Couldn't find any versions for "react" that matches "latest" in our cache. Possible versions: ""
info Visit https://yarnpkg.com/en/docs/cli/add for documentation about this command.

Aborting installation.
  yarnpkg add --exact --offline react react-dom react-scripts has Failed.

Deleting generated file... package.json
Deleting my-app / from F:\react
Done.

解决方法

作为一种解决方法,首先尝试在空文件夹中运行yarn add react react-dom react-scripts.这会将所需的包添加到yarn的本地缓存中.然后,您可以删除该文件夹并再次运行create-react-app my-app,它将有希望工作.
