## You may also need development tools to build native addons: sudo apt-get install gcc g++ make ## To install the Yarn package manager, run: curl -sL https://dl.yarnpkg.com/debian/pubkey.gpg | gpg --dearmor | sudo tee /usr/share/keyrings/yarnkey.gpg >/dev/null echo "deb [signed-by=/usr/share/keyrings/yarnkey.gpg] https://dl.yarnpkg.com/debian stable main" | sudo tee /etc/apt/sources.list.d/yarn.list sudo apt-get update && sudo apt-get install yarn
Installing nodejs now automatically installs npm.
(Debian gets v7.5.2, Ubuntu gets v6.14.15)
attempting to install npm (on Debian)now causes:
Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation: The following packages have unmet dependencies: libnode72 : Conflicts: nodejs-legacy nodejs : Conflicts: npm E: Unable to correct problems, you have held broken packages.
