When I typed “npm install”, it will stuck at:

“make: Leaving directory `/home/openproject/openproject-ce/frontend/node_modules/protractor/node_modules/selenium-webdriver/node_modules/ws/node_modules/bufferutil/build’ ”

After I issued the commands below:

rm -fR ~/.npm
npm cache clean

run again with “npm install”, it show up these errors:
