# Script that installs the project node module dependencies within Travis. The script also ensures that the cached

|
# project `package.json` file.

# 1) Cached node modules are not in sync with lock file

# 2) Lock file is not in sync with `package.json`

# In case the integrity check passes, we just use the cached/locked node modules. If it fails, we want to purge the

|
||
|
|
# modules will be refreshed to **match** the actual lock file. Otherwise, if the `package.json` does not match with
|
||
|
|
# the lock file, Yarn automatically throws an error due to the `--frozen-lockfile` option.
