mac 安装 hexo-cli 失败

Question

节点版本为：

node -v
v8.9.1

我尝试按照official guide安装hexo-cli：

npm install -g hexo-cli

并得到错误：

然后我至少尝试了 5 次相同的命令并得到相同的错误。我也尝试添加 sudo ：

sudo npm install -g hexo-cli

并且发生了同样的错误。

据我所知，yarn add的功能等于npm install，所以我试了一下：

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warning Your current version of Yarn is out of date.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.

看来hexo-cli已经安装成功了。但是当我运行命令 hexo 时，它显示：

hexo
-bash: hexo: command not found. 

好像是npm的问题，但是不知道怎么解决。任何想法？提前致谢。

Answer 1

试试yarn global add hexo-cli

global 是 npm 的 yarn 的 -g
