I'm using phpstorm 2019.2 on Macbook pro with macOS 10.15.
When I open or close a project in phpstorm, ALL node.js processes was killed with signal 9(SIGKILL), even if the node.js processes is not started with phpstorm, and even if the node.js processes do nothing.
1. Open a terminal ( I'm using iTerm )
2. run "node" command ( NO MATTER WHAT THE VERSION OF NODE.JS )
3. open phpstorm
4. open a project in phpstorm
5. NOW, the node is killed with signal 9!
