Library Dependency Issue


I am trying to add a dependency to one of my libraries from another but I am getting the error:

Error: Could not find `Micro Debug` dependency for `ArduinoMongoose` library

eg Travis CI - Test and Deploy Your Code with Confidence

The library.json for the ArduinoMongoose library is:

  "name": "ArduinoMongoose",
  "keywords": "network",
  "description": "Arduino style wrapper arround Mongoose library",
    "type": "git",
    "url": ""
      "name": "Jeremy Poulter",
      "email": "",
      "maintainer": true
  "version": "0.0.2",
  "frameworks": "arduino",
  "platforms": "*",
  "dependencies": [
      "name": "Micro Debug",
      "version": "~0.0.2"

and Micro Debug is registered ok, PlatformIO Registry and if you install from the command line it works fine, eg

pio lib install "Micro Debug"

One oddity that may be related, I did have to change the name from MicroDebug to Micro Debug to avoid a conflict with PlatformIO Registry

Anyone any ideas?

This is a feature of current PlatformIO Core 3.0. I’ve just opened an issue for this case

A temporary solution is to replace your line in .travis.yml from

- ln -sf $TRAVIS_BUILD_DIR ~/.platformio/lib


pio lib -g install $TRAVIS_BUILD_DIR

Ah, thanks. That is probably ok for CI, but for local dev it would be nice to have something similar to NPM’s npm link
