Answer 1

When installing global packages in ubuntu, you need special write permissions as you are writing to the usr/bin folder. It is for security reasons.

So, everytime you install a global package, use:

sudo npm install -g [package-name]

for your specific case:

sudo npm install -g typescript

When you try it without -g all that you are doing is installing the package locally in whatever folder you are in:

so: npm install typescript will create a node_modules folder in the folder you are in.
