Currently, node.js depends on inspector_protocol indirectly through the dependency on v8. This is a dependency violation that will make it hard to roll V8 into Node if V8 gets a newer inspector protocol version with incompatible API. In fact, this surfaced on one of our bots when we tried to roll new inspector_protocol into V8. This patch adds inspector protocol and its required dependencies to node deps: - jinja2 - markupsafe PR-URL: https://github.com/nodejs/node/pull/21975 Reviewed-By: Eugene Ostroukhov <eostroukhov@google.com> Reviewed-By: Aleksei Koziatinskii <ak239spb@gmail.com>
