    # This must be run after setting up the plugin, 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    # tools such as `npm outdated`, `npm update`, and some ESLint rules.
