assume that the installation directory for yarn is / usr/app/yarn-v1.13.0/.
execute:
ln -s /usr/app/yarn-v1.13.0/bin/yarn /usr/bin/yarn-jsuse:
yarn-js -v-additional note-
generally, all tools you install will have a / bin directory in their directory, which contains the executable files for the tool, such as yarn.
ln command do?
established a connection.
/ usr/bin/yarn-js is the executable of the system and is named yarn-js (the name is optional, but not conflicting).
ln-s / usr/app/yarn-v1.13.0/bin/yarn / usr/bin/yarn-js is to link yarn-js to / usr/app/yarn-v1.13.0/bin/yarn, the executable file for your installation yarn.
so that when you execute yarn-js, you are actually calling the yarn execution under the installation path.
aside: why configure the system path path? The answer is same as above.
