安装reactjs时出错:解析附近时，JSON输入意外结束错误 [英] Error installing reactjs: Error unexpected end of JSON input while parsing near

问题描述

我尝试使用1)npx create-react-app my-app和2)npx create-react-app app

I tried installing reactjs via node using two different commands in the terminal using 1) npx create-react-app my-app and 2) npx create-react-app app

但是两者都产生了如下所示的相同错误:

But both yielded the same error shown below:

安装软件包.这可能需要几分钟.

Installing packages. This might take a couple of minutes.

使用cra-template安装react，react-dom和react-scripts ...

Installing react, react-dom, and react-scripts with cra-template...

中止安装.

npm install --save --save-exact --loglevel错误反应react-dom react-scripts cra-template失败.

npm install --save --save-exact --loglevel error react react-dom react-scripts cra-template has failed.

我尝试卸载并重新安装节点，还尝试安装不同版本的reactjs，但仍然遇到相同的错误.另外，我尝试清除节点缓存，然后再次通过npm cache clear --force和npm cache verify对其进行验证，但是仍然没有任何运气.任何帮助将不胜感激.

I tried uninstalling and reinstalling node and also trying to install different older versions of reactjs but still got the same error. Also, I have tried clearing the node cache and then verifying it again via npm cache clear --force and then npm cache verify but still have not had any luck. Any help will be greatly appreciated.

推荐答案

使用节点包管理器安装yarn为我解决了该问题.打开命令提示符，然后输入:

Installing yarn using node package manager fixed the issue for me. Open command prompt and enter:

npm install -g yarn
