NPM breakthrough with test packages and weird error

[swedebugia@riseup.net]

Hi

I have good (and bad) news!

Today I worked intensely on the node-build-system, importer and made
some improvements as I ran into multiple errors using the importer and
building the packages.

I tried first importing tape (test package, quite popular) and succeded
with a few adjustments.

Then I tried tap, its a hairy mess unfortunately and pulls in del,
typescript, grunt, nyc, and others

I write this message mostly because I now receive a really weird error
from guix.

sdb@antelope ~/src/guix$ ./pre-inst-env guix build -K node-grunt
guix build: error: build failed: invalid hash
`72bd690b3fbd3be123e66c0c1932d856b294931d134cd07d4d4cd6aa1e07'
sdb@antelope ~/src/guix$ ./pre-inst-env guix build -K
node-tap-mocha-reporter
guix build: error: build failed: invalid hash
`72bd690b3fbd3be123e66c0c1932d856b294931d134cd07d4d4cd6aa1e07'

The error is the same across multiple packages. Builds "succeede" as
usual if they are already in the store or unrelated to grunt and nyc.

After investigating with strace I found this in the end:

[pid  8371] read(13, "download", 8)     = 8
[pid  8371] write(13,

How did I get a corrupted store? No idea. How to delete single items? 

I found this email from 宋文武 from 2016

"> How do I get rid of these ca. 30 outdated store items?
I think call gc for each one will work, eg:

for i in /gnu/store/*teensy*; do guix gc -d $i; done"

I adapted it to *minimatch* and deleted them all and checked the store
manually for any minimatch left and... it still did not work.

Hm.

Removed the hash for minimatch from the node.scm. Tried again. No luck.

Time to repair the store? Update the daemon via reconfigure?

I run vanilla 0.16.
