我试图安装 Node.js、Grunt 和 Harp，所以我下载了 Node.js，然后我在终端中写了这个（注意：我也有 Homebrew）： node -v

npm update -g npm
npm install -g grunt-cli

之后我安装了 Bootstrap 文件并写了（总是从终端）我写了：

npm install

终端返回了这个：

[bash-3.2# npm install
npm WARN saveError ENOENT: no such file or directory, open '/Users/Bimbi/package.json'
npm WARN enoent ENOENT: no such file or directory, open '/Users/Bimbi/package.json'
npm WARN Bimbi No description

之后，我运行这些命令来更新 Ruby，安装 bundler 和一些依赖项：

\curl -sSL https://get.rvm.io | bash -s stable
rvm list known
rvm install ruby-2.4.2
ruby -v
rvm use ruby-2.4.2 —default
gem install bundler
bundler -v
gem init
bundle install
gem install Jekyll bundler

然后我尝试安装竖琴：

sudo npm install -g harp

终端返回了这个：

npm WARN deprecated connect@2.30.2: connect 2.x series is deprecated
npm WARN deprecated graceful-fs@3.0.11: please upgrade to graceful-fs 4 for compatibility with current and future versions of Node.js
npm WARN deprecated coffee-script@1.12.7: CoffeeScript on NPM has moved to "coffeescript" (no hyphen)
/usr/local/bin/harp -> /usr/local/lib/node_modules/harp/bin/harp
+ harp@0.25.0
updated 1 package in 9.639s

收到此消息后，我跑了：

harp -V

控制台返回：
