npm -g install npm@next?

[zetsin]

Thanks a lot, @addaleax 👍

Something wrong happened:

"...\npm\node_modules\npm\node_modules\node-gyp\src\win_delay_load_hook.cc':** No such file or directory

after npm -g install npm@next

So I did that:

cd "...\npm\node_modules\npm\
npm install

It works, finally

[addaleax]

Something wrong happened:

That does not look like something that should happen. Do you still have the npm-debug.log from that installation attempt?

[zetsin]

Let me do it again.

rd/s/q "...\npm\node_modules\npm"
npm -g install npm@next
cd "...\npm\node_modules\npm\node_modules\node-gyp"
dir

I found that there is no "src" folder in "node-gyp", so the wrong happened when i use node-gyp build(e.g. npm install ref)

"...\npm\node_modules\npm\node_modules\node-gyp\src\win_delay_load_hook.cc':** No such file or directory

[bnoordhuis]

cd "...\npm\node_modules\npm\node_modules\node_gyp"

Is that a typo? The directory is called 'node-gyp', not 'node_gyp'.

[zetsin]

Yeah, its a typo I have edited, i'm so sorry. @bnoordhuis

[bnoordhuis]

No problem. Just to be sure, can you delete your node_modules directory and install npm@next again?

If you still can't build ref, can you post the full build log of npm install ref?

[RanzQ]

I found a workaround, go to AppData\Roaming\npm\node_modules\npm and type npm remove node-gyp then npm install node-gyp.

I think this is due to using npm-windows-upgrade. It guides to use --production flag so I guess it installs npm with --production too. So node-gyp was missing src/.

First I had a problem that the upgrade was installing npm@3.10.3 and it had the previous node-gyp. I posted a comment about it. So I had node-gyp@3.4.0 in my global node_modules but 3.3.1 inside npm.

Anyway, now I'm finally able to build. :)

fwiw npm@next is probably not going to fix this, yet, there was a problem in the upgrade that went out with 3.10.4, see npm/npm#13256 (my fault somehow I believe). It's been fixed in tree and I imagine it'll be out soon in a 3.10.5. npm@2 works fine though if you're able to use v2.

@rvagg I think I may have the same issue with npm 2.14.12. I have pretty much the same environment as @zetsingithub, except for the npm version. I was trying to install mariasql and got:

win_delay_load_hook.c

  C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\include\delayimp.h(134
  ): note: see declaration of '__pfnDliNotifyHook2'

Do you know if this issue might affect npm@2 as well?

[rvagg]

yep, you need 2.15.9: https://github.com/npm/npm/releases/tag/v2.15.9
I think npm i npm@2 -g should be enough to upgrade you, we don't carry it in our Node LTS releases yet but it'll get there.

[Vasanthrajan]

@rvagg That did the trick, Thank you!

[SwadicalRag]

Had the same issue, npm -g install npm@next fixed it for me, if anyone else is in the same boat.
