Install fails because module 'is-property' isn't installed

[frankhale]

I think electron-prebuilt needs to include a dependency on module is-property because on my system it's bombing out and can't install because that module is missing. After I manually installed is-property electron-prebuilt installed correctly.

C:\Users\Frank\Desktop>npm install -g electron-prebuilt
C:\Users\Frank\AppData\Roaming\npm\electron -> C:\Users\Frank\AppData\Roaming\np
m\node_modules\electron-prebuilt\cli.js

> [email protected] postinstall C:\Users\Frank\AppData\Roaming\npm\node_m
odules\electron-prebuilt
> node install.js

This happened to me on two different Windows machines.

@frankhale thanks for the bug report. This is super weird behavior. @mafintosh have you ever seen this before?

[justinmchase]

👍 This is happening to me too.

[justinmchase]

As a work-around you can just install is-property globlally and then it will work:

npm install is-property -g

[gcoupelant]

+1 @justinmchase tip worked

[mafintosh]

what version of npm are you using? this should never happen as is-property is a dependency of generate-object-property (which is throwing this error)

[frankhale]

Not sure exact version of npm but I was using iojs 2.2.1 at the time.

[frankhale]

Actually it's in the log message posted above:

npm ERR! node v2.2.1
npm ERR! npm  v2.11.0

[gcoupelant]

Same with me, io.js installed with chocolatey on Windows 10
node v2.2.1 and npm v2.11.0

[mafintosh]

@frankhale @gcoupelant this seems to be an npm issue. is this reproducible on subsequent installs?

[frankhale]

I'll see if I can reproduce it using iojs 2.3.0 as soon as I have time today.

[dominhhai]

Same with me in Win 7 - 64 bit, and iojs 2.2.1.

[v12]

Experiencing same issue:

• Platform: Win 8.1 x64
• io.js: v2.3.0
• npm: v2.11.1

[max-mapper]

I think this is a windows specific issue because we are using too many modules and windows paths have a hard limit on length. I'll look into a fix

[v12]

@maxogden you're right, seems to be io.js bug, which was introduced in v2.2.0 (nodejs/node#1801) and fixed in v2.3.1 (nodejs/node@a4f4909).

If you use any version of io.js in-between 2.2.0 and 2.3.0 inclusive, it fails to load any module that has path length greater than 259 characters in those versions.

[frankhale]

Thanks @v12 for this information! I removed electron-prebuilt, removed is-property, installed iojs 2.3.1 and then reinstalled electron-prebuilt and it installed without issue.

[snowcxt]

I'm using node v4.0.0. I still have this problem on my Windows.

[frankhale]

@snowcxt, try installing the is-property module and then install electron-prebuilt and see if that works.

[snowcxt]

I tried that. Didn't work for me. BTW I only get this error when I use Request

[justinmchase]

@snowcxt You tried to install it globally? Like this: #40 (comment)

[snowcxt]

You mean npm install is-property -g? Yes
