The presence of "Darwin 13.2.0" tells me you're using a Mac. Did you install libvips via homebrew? If so, pkg-config is included as a build-time dependency.

It looks like the pkg-config executable is either missing or at a location the command line cannot access. What do the following two commands return on your machine?

whereis pkg-config
which pkg-config

[pierreinglebert]

Maybe we should add a link to the brew installation instructions in the MacOS installation paragraph.

[lovell]

@pierreinglebert I'm planning to add a "bootstrap/configure" check to npm install that verifies the system and dependencies are OK, providing platform-specific installation instructions for anything missing.

(See #42 (comment) for the genesis of this idea.)

[lovell]

Hi @eonezhang, there are a few improvements to determining the pkg-config path in v0.5.1. Are you able to retry using the latest version from npm?

[lovell]

Hi @eonezhang, have you been able to make any progress with this problem?

[lovell]

Closing due to inactivity. Please feel free to re-open if the problem persists. Thanks!

Hi @lovell
Trying to install sharp dependency in package.json
'npm install node-gyp --s'
'npm install sharp --s'
I get no errors. Node-gyp appears in the dependency but sharp is nowhere to be found.
What am I missing?

[lovell]

@Cedric12114 Is your use of the --s flag intentional? It means npm will be "silent" and suppress errors. Perhaps try without and see what is says. Feel free to open a new issue if there's an error that no one else has previously reported.
