I got an error when I did the following.
create-react-app react_lessons
Creating a new React app in /var/www/html/react_lessons/react_lessons.
Installing packages. This light take a couple minutes.
Installing react-scripts...
npm WARN optional dep failed, continuing [email protected]
npm install --save-dev --save-exact react-scripts failed
The above error occurred more than 30 minutes after executing the command.
When I checked the directory, it seems that the files have been generated.
The package.json was also automatically generated, so I checked and found only the following description.
"name":"react_lessons",
"version": "0.1.0",
"private"—true
I wonder if the react-scripts installation has failed.
What is the best solution for these situations?
Error running npm install-g create-react-app as supplementary information

There seems to be a high possibility that it was bad.

It worked well here in our environment.
I'm sorry if I gave you the wrong information due to the root cause.
I am sorry to trouble you, but I would appreciate it if you could point it out.
You do not need to use sudo to install create-react-app. How did you install npm?
$whichnpm
/Users/<username>/.nodebrew/current/bin/npm
Also, try a directory that is not /var/www/html/.
$cd to
$ npx create-react-app react-lessons
