+## Troubleshooting
+
+### Ignoring optional dependencies
+
+When running `npm install`, you can get warnings about optionsl dependencies:
+
+```
+npm WARN optional Skipping failed optional dependency /chokidar/fsevents:
+npm WARN notsup Not compatible with your operating system or architecture: fsevents@1.2.7
+```
+
+You can suppress them by adding the `no-optional` switch:
+
+```
+npm install --no-optional
+```

+
+### Resolving dependencies
+
+When installing for the first time, you can get warnings which need to be resolved:
+
+```
+npm WARN eslint-config-scratch@5.0.0 requires a peer of babel-eslint@^8.0.1 but none was installed.
+npm WARN eslint-config-scratch@5.0.0 requires a peer of eslint@^4.0 but none was installed.
+npm WARN scratch-paint@0.2.0-prerelease.20190318170811 requires a peer of react-intl-redux@^0.7 but none was installed.
+npm WARN scratch-paint@0.2.0-prerelease.20190318170811 requires a peer of react-responsive@^4 but none was installed.
+```
+
+You can check which versions are available:
+
+```
+npm view react-intl-redux@0.* version
+```
+
+You will neet do install the required version:
+
+```
+npm install  --no-optional --save-dev react-intl-redux@^0.7
+```
+
+The dependency itself might have more missing dependencies, which will show up like this:
+
+```
+user@machine:~/sources/scratch/scratch-gui (491-translatable-library-objects)$ npm install  --no-optional --save-dev react-intl-redux@^0.7
+scratch-gui@0.1.0 /media/cuideigin/Linux/sources/scratch/scratch-gui
+├── react-intl-redux@0.7.0
+└── UNMET PEER DEPENDENCY react-responsive@5.0.0
+```
+
+You will need to install those as well:
+
+```
+npm install  --no-optional --save-dev react-responsive@^5.0.0
+```
