forbidden in Fedora. For more information, see:

It is generally reccomended to remove the entire "node_modules" directory in

%prep when it exists. For more information, see:

<https://fedoraproject.org/wiki/Packaging:Node.js#Removing_bundled_modules>

If you have obtained permission from the Fedora Packaging Committee to bundle
|
|
libraries, please use `%nodejs_fixdep -r` in %prep to remove the dependency on
|
|
the bundled module. This will prevent an unnecessary dependency on the system
|
|
version of the module and eliminate this error.
