如何解决错误：找不到模块'json-parse-helpfulerror'

Question

In Windows, I tried to create a new application form of this site: https://facebook.github.io/react/docs/installation.html

First, I installed Node.js v8.2.1 and when I execute npm install -g create-react-app , I get the following error:

npm ERR! code MODULE_NOT_FOUND
npm ERR! Cannot find module 'json-parse-helpfulerror'

npm-debug.log:

Answer 1

在目录文件夹中，发出以下命令：

npm update

Answer 2

Remove npm and reinstall it

And run:

sudo rm -rf /usr/local/{lib/node{,/.npm,_modules},bin,share/man}/npm*

Answer 3

Seeing what is requested in the Users folder, it seems that it should be installed as a global package.

Check and install each required package.

npm i -g json-parse-helpfulerror

Answer 4

1. You must uninstall nodejs and npm packages.
2. after first, you must install npm.
3. and you should install "npm install --save json-parse-better-errors"
4. Finally you can run your project

https://www.npmjs.com/package/json-parse-better-errors

Answer 5

I fixed it by removing the node_modules folder and reinstalling it again. To remove the folder, go to your project folder and run $ rm -rf node_modules and then reinstall your packages using your preferred package manager, either npm i or yarn install .
