installing yarn globally on mac

Question

i have an Imac and i tried installing yarn globally with npm and i got these error:

npm ERR! syscall mkdir
npm ERR! path /usr/local/lib/node_modules/yarn
npm ERR! errno -13
npm ERR! Error: EACCES: permission denied, mkdir '/usr/local/lib/node_modules/yarn'

npm ERR! }
npm ERR!

I have tried sudo but it requires a password and note that this is a new system and does not have any passwords set, i have researched to see if there are similar problems but haven't found any. If you do have a solution to this problem i would really appreciate it if you help me out and solve this. Thank you..

Answer 1

can you try to use a blank password?

UNIX bases systems always have a root user and they tend to have no password, when it was set first. So when the console is asking you for a password, just press ENTER.

The error even says that you have insufficient permissions.
