When installing YouCompleteMe for vim, I want to install support for Java and Javascript. Following instructions from here, I therefore run:
sudo /usr/bin/python3.6 ./install.py --java-completer --ts-completer
However, it errors out with the following message:
...

ERROR: Unable to find executable 'npm'. npm is required to install TSServer.
This would be understandable, except I have npm already set up on my PATH, as shown by the following:
=> npm -v
6.13.4
=> which npm
/home/vagrant/.nvm/versions/node/v8.17.0/bin/npm
Any guesses on why YouCompleteMe with ts-completer support is failing to install?

The install fails because you are running install.py as sudo, and the location that nvm installs node is not in the secure_path. The secure_path is in use when a script runs as sudo.
You can see the different contents of PATH and secure_path like this:
$ echo 'echo $PATH' | sudo sh # secure_path
$ echo 'echo $PATH' | sh # your user PATH
You can also confirm that sudo lacks an npm on its path like this:
$ which npm
$ sudo which npm
What to do?
One option is to run the script without sudo like this:
/usr/bin/python3.6 ./install.py --java-completer --ts-completer
Another is to copy the nvm bin contents to one of the secure_path locations. The /usr/local/bin is one of those.
$ find $(which npm | xargs dirname) -type l -o -type f | sudo xargs cp -t /usr/local/bin
# test
$ sudo npm -v
$ sudo node -v
After doing that, the installer will find npm.
