Failed to install hexo-cli on mac

Question

The node version is:

node -v
v8.9.1

I tried to install hexo-cli by following the official guide:

npm install -g hexo-cli

and got the errors:

And then I tried the same command at least 5 times and get the same errors. I also tried to add sudo :

sudo npm install -g hexo-cli

and the same error occurred.

As far as I am concerned, the function of yarn add equals to npm install, so I tried:

yarn add hexo-cli -g
yarn add v0.27.5
info No lockfile found.
[1/4] Resolving packages...

success Saved lockfile.
warning Your current version of Yarn is out of date. The latest version is "1.3.2" while you're on "0.27.5".
info To upgrade, run the following command:
$ npm upgrade --global yarn
success Saved 180 new dependencies.

It seems that the hexo-cli has been installed successfully. But when I run the command hexo it shows that:

hexo
-bash: hexo: command not found. 

It seems to be a problem with npm, but I don't know how to solve it. Any idea? Thanks in advance.

Answer 1

try yarn global add hexo-cli

global is yarn's -g of npm
