user@hostname:/var/www/html/laravel$

The command is actually a false one since the output of the command is hinting the correct way for executing npm to install a module which in this context is JQuery. After the information given that an update is available, it has been decided to update the npm utility first before executing further operation.

 Try to update the npm tool by executing the following command with the output generated :

npm ERR! A complete log of this run can be found in:

Based on the output above, the update process cannot be done using a normal user account. The update process need to be done in root account. So, as shown in the output below using root account try to update npm module :

root@hostname:/var/www/html/laravel# npm i -g npm
/usr/local/bin/npm -> /usr/local/lib/node_modules/npm/bin/npm-cli.js
/usr/local/bin/npx -> /usr/local/lib/node_modules/npm/bin/npx-cli.js
+ npm@5.5.1
added 52 packages, removed 2 packages and updated 29 packages in 18.042s
root@hostname:/var/www/html/laravel#

As shown in the above output, the process for updating npm has already finished.

As for the previous failure command, to install module itself can be done by executing the following command :

npm install jquery
