Node.js 无法在mac上安装hexo cli

节点版本为：

node -v
v8.9.1

我尝试通过以下方式安装hexo cli：

并得到了错误：

然后，我尝试了相同的命令至少5次，并得到相同的错误。我还尝试添加sudo：

sudo npm install -g hexo-cli

同样的错误也发生了

就我而言，

纱线添加

的功能相当于

npm安装

，因此我尝试：

yarn add hexo-cli -g
yarn add v0.27.5
info No lockfile found.

warning Your current version of Yarn is out of date. The latest version is "1.3.2" while you're on "0.27.5".

似乎已成功安装hexo cli。但当我运行命令hexo时，它显示：

hexo
-bash: hexo: command not found.

这似乎是npm的一个问题，但我不知道如何解决它。有什么想法吗？提前感谢。

尝试

纱线全球添加hexo cli

global

是纱线的

-g

的npm

尝试
