安装react时如何解决“找不到项目”错误

Question

I am new to react and i am taking my first course on openclassrooms on react. The instructor is using the command yarn global add create-react-app
to setup but when i run the commdand i get the error below

Usage Error: No project found in /E:/Web Dev/React/react-project

i have tried to use the command below that is provided in the react documentation but i stil get the same error

yarn create react-app my-app

How can i solve the problem i have looked up on the react documentation but still cannot find the solution.

Answer 1

I experienced the same issue and solved it as follows:

1. Uninstall yarn from npm using npm uninstall -g yarn
2. Install Yarn from Installation - Yarn Classic
3. Restart PowerShell / CMD

Before performing the above steps yarn --version printed 2.0.0-rc.27 on my machine. Now it prints 1.22.4 .

Having Yarn 2.x globally installed is discouraged accourding to Installation - Yarn 2.x .
