Create-react-app返回“找不到模块'rxjs'". [英] Create-react-app returns "Cannot find module 'rxjs'"

问题描述

我刚刚在新机器上安装了NodeJS和NPM.我在所有现有项目中添加了 rxjs 包，以使其正常启动.但是，当我运行 create-react-app 时-全局使用npm或npx-我收到错误:找不到模块'rxjs'.似乎 rxjs 是某种事物的新依赖项(考虑到它也会影响旧项目).

I've just installed NodeJS and NPM in a new machine. I added rxjs package in all my existing projects in order to make then start properly. However, when I run create-react-app - using npm globally or npx - I receive "Error: Cannot find module 'rxjs' ". Seems like rxjs is a new dependency of something (considering it's affecting old projects too).

我已经将Node版本更改为8、10和12.重新安装了NPM，将CRA版本更改为2.x.x，问题仍然存在.

I have already changed Node version to 8, 10 and 12. Reinstalled NPM, changed CRA version to 2.x.x and the trouble persists.

如何在没有此问题的情况下使用CRA?

How can I use CRA without this problem?

推荐答案

正如原始海报在评论中所述，解决方法可能是清除缓存.

As mentioned by the Original Poster in the comments, the fix could be to clear your cache.

npm缓存清理--force

如果仍然无法执行，则可以按照以下步骤安装并尝试使用Yarn:

If this still doesn't work, you can follow the steps below to install and try with Yarn:

如果 npx create-react-app my-app 和 npm init react-app my-app 都不适合您，请尝试使用Yarn看看效果如何.

If neither npx create-react-app my-app and npm init react-app my-app are working for you, try Yarn to see how it goes.

我曾经使用CRA在Windows，Ubuntu，Mint和macOS上进行过多个项目，但从未明确安装rxjs，也没有要求我这样做.这使我认为，这个问题几乎可以肯定是由 you 引起的，而不是CRA的错误.我认为您已经在Github上搜索了他们的问题.

I have used CRA is multiple projects on Windows, Ubuntu, Mint and macOS and have never explicitly installed rxjs, nor have I been asked for it. This leads me to think that this problem is almost certainly caused by sth local to you rather than sth wrong with CRA. I assume that you have searched through their issues on Github.

尝试使用纱线打开一个新的终端(Linux和macOS)或命令行(Windows)会话，将其cd到您的documents文件夹或其他合适的文件夹.然后运行:

Try it with Yarn Open a new terminal (linux and macOS) or command line (Windows) session cd'd to your documents folder or suitable alternative. Then run:

macOS

酿造纱线

yarn create react-app my-app

Windows(含Chocolatey)

Windows (with Chocolatey)

choco install yarn

yarn create react-app my-app

Ubuntu

curl -sS https://dl.yarnpkg.com/debian/pubkey.gpg |sudo apt键添加-

echo"deb https://dl.yarnpkg.com/debian/stable main" |sudo tee/etc/apt/sources.list.d/yarn.list

sudo apt-get update&&sudo apt-get install yarn

yarn create react-app my-app
