npm publish test repository

Issue: npm#12498 → npm#5082 Status: Identified

Problem

When I upgraded to Node 6, it came shipped with npm@3.8.6. I released new versions from some packages and after using those packages, my index.js file was not published. At first I thought that it only affected me, "I must have done something wrong!". But it appeared that Sindre Sorhus released his array-differ package after installing Node 6 and suffered from the same bug.

In the following case, the bug always occurs.

• Add index.js to the files property in package.json
• Have node_modules directory with your dependencies
• Have a .gitignore file which ignores the node_modules directory

Why

The improved performance of fs.realpath has changed the timing and order of operations enough that it greatly exacerbates the race condition.

So probably something goes wrong because Node 6 improved the performance of fs.realpath.

Test

Go to your module directory and run the following command

$ npm pack

This will generate a tarball just like the one that will be published. So extract the contents and take a look if some files are missing.

Solution

You have two options

1. Downgrade npm to npm@2 and republish your package!
2. Remove the node_modules directory first before publishing

I can't say 100% for sure that option 2 always works. You can always test with npm pack before publishing.
