Out of the box create-react-app failing due to uglify-webpack-plugin

Is this a bug report?

Yes

Can you also reproduce the problem with npm 4.x?

Yes, I am running npm 5.5.1

I rolled npm back to version and I’m still having the exact same issues.

Which terms did you search for in User Guide?

(Write your answer here if relevant.)

Environment

1. node -v: 8.8.1
2. npm -v: 4.6.1 (After rolling back, no effect on newer version)
3. yarn --version (if you use Yarn): 1.0.0
4. npm ls react-scripts (if you haven’t ejected): N/A

Then, specify:

1. Operating system: Mac
2. Browser and version (if relevant):

Steps to Reproduce

(Write your steps here:)

1. run create-react-app <Name of project>
2. create-react-app fails on uglify-webpack-plugin

Expected Behavior

Would create a new application

Actual Behavior

When I run create-react-app it fails when looking for uglifyjs-webpack-plugin. I have searched the posts on this topic already and installed the beta uglify-webpack plugin that I’ve seen and still nothing. Not sure what else to do. I’ve uninstalled and reinstalled node, npm and create-react-app. I’ve rolled back my npm. I will post a photo of my terminal.

Reproducible Demo

Since the script calls node lib/post_install.js instead of node ./lib/post_install.js I’m wondering if you have any custom config around NODE_PATH or any environment variable that may affect the current working directory for these scripts and or node’s file resolution.

FYI, I had the same problem. Uninstalled yarn and it worked.
