# Plugins must be installed before installing Etherpad's dependencies, otherwise
# npm will try to hoist common dependencies by removing them from
# src/node_modules and installing them in the top-level node_modules. As of
# v6.14.10, npm's hoist logic appears to be buggy, because it sometimes removes
# dependencies from src/node_modules but fails to add them to the top-level
# node_modules. Even if npm correctly hoists the dependencies, the hoisting
# seems to confuse tools such as `npm outdated`, `npm update`, and some ESLint
# rules.
