sharp: Meteor: "Unable to resolve some modules"

Hi,

I would like to use sharp for image manipulation in a meteor project I am working on. I add the sharp dependency in my package.json: "sharp": "^0.15.1"

I didn’t add any dependencies

When start the app, I have this error:

Unable to resolve some modules:

  "path" in /mnt/vdb/web/site-LBF/node_modules/sharp/index.js (web.browser)
  "util" in /mnt/vdb/web/site-LBF/node_modules/sharp/index.js (web.browser)
  "stream" in /mnt/vdb/web/site-LBF/node_modules/sharp/index.js (web.browser)
  "events" in /mnt/vdb/web/site-LBF/node_modules/sharp/index.js (web.browser)
  "./build/Release/sharp" in /mnt/vdb/web/site-LBF/node_modules/sharp/index.js (web.browser)

Theses modules are not the dependencies listed in the npm page. I tried to add the dependencies to the package.json:

"tar": "^2.2.1", 
    "request": "^2.74.0", 
    "semver": "^5.3.0", 
    "nan": "^2.4.0", 
    "color": "^0.11.3", 
    "bluebird": "^3.4.1",
    "sharp": "^0.15.1"

It doesn’t change anything.

Am I missing any prerequisites ?

Thanks
