npm ERR! Cannot read property '0' of undefined #18042

CarpenterBug · 2017-08-02T11:45:43Z

I'm opening this issue because:

npm is crashing.
npm is producing an incorrect install.
npm is doing something I don't understand.
Other (see below for feature requests):

What's going wrong?

npm install webpack-livereload-plugin -D

npm info lifecycle undefined~preuninstall: undefined
npm info lifecycle undefined~uninstall: undefined
npm WARN ajv-keywords@1.5.1 requires a peer of ajv@>=4.10.0 but none was installed.

npm ERR! A complete log of this run can be found in:

How can the CLI team reproduce the problem?

This looks like a duplicate of #17858

CarpenterBug · 2017-08-02T15:53:54Z

Thank you for pointing that out @robinhouston, one of the comments have the solution for this issue.

Solution: delete node_modules folder and package-lock.json file.

Closing and out!

lukrizal · 2017-09-14T05:08:51Z

in my case, I solve the problem by:

Reinstalling build-essentials(for Debian) and gcc-c++ make(for Fedora)
Downgrading from 5.4 to 5.3

vgvinay2 · 2017-09-14T09:51:11Z

node6.9.3
npm 5.3.0

downgrading to 5.2 solve the problem

garenyondem · 2017-11-09T12:21:46Z

The same error happened to me now. Downgrading from 8.9.0 to 6.11.x solved the problem.

fabioimpe · 2017-11-09T12:23:50Z

Same problem for me too, deleted the node_modules folder and then it worked

MuneebSaeed · 2017-11-09T15:21:51Z

Nothing is working for me.
I deleted node_modules and lock.json (both was in the project)
Downgrade to
node: v8.1.3
npm: 5.2.0

but still facing same issue.
@fabioimpe can you please confirm which node_module folder should delete?
one is in the project and the other is in lib root folder (/usr/local/libs)
and which versions should i use for npm and node?

fabioimpe · 2017-11-09T16:29:58Z

@MuneebSaeed
I'm on node 7.9.0 and npm 5.5.1
I just deleted the node_modules in the project folder

MuneebSaeed · 2017-11-10T10:20:39Z

@fabioimpe i dont know whats going on with my project...
Should i install everything again?? May be there are multiple nodes or npm??

DavidTheProgrammer · 2017-11-13T09:58:14Z

npm cache clean --force fixed it for me

node version 8.9.1
npm 5.2.0

MuneebSaeed · 2017-11-14T06:43:25Z

oh! I don't know why it worked now. I have already done cache clean many times but this time it happened.
I just update my node to 8.9.1
and npm 5.2.0

Thanks everybody! You people are awesome.

Had a nightmare with "npm ERR! Cannot read property '0' of undefined".
The problem was with npm version.
This resolved the issue:

npm install npm@5.2.0 -g
npm cache clean --force
npm install

Cheers!

Use "yarn"
Spend ~two days looking at npm issues, over and over. Installed yarn, everything worked on first try.

Fix: npm/npm#17858 Fix: npm/npm#18042 Fix: https://npm.community/t/issue-npm-dedupe-crash-with-typeerror-cannot-read-property-0-of-undefined/644/3 Close: #201 This fixes a bug where a package folder might have a package.json which is missing or lacks a name property. It also properly detects the scoped-ness of a package folder even if the package name is not scoped, since one might install `express@npm:@scope/express` and end up in that state.
