提问by Alex Getty

Following these instructions (http://www.nodebeginner.org), I installed node, created a simple helloworld.js file, then ran this command in the terminal:
我正在设置 node.js 以便与 Meteor、Derby 或 Ember 等框架一起使用，但在早期遇到了一些问题。按照这些说明 (http://www.nodebeginner.org)，我安装了 node，创建了一个简单的 helloworld.js 文件，然后在终端中运行这个命令：

The problem is that your PATH does not include the location of the node executable.
问题是您的 PATH 不包含节点可执行文件的位置。
You can likely run node as "/usr/local/bin/node".
您可能可以将节点运行为“ /usr/local/bin/node”。
You can add that location to your path by running the following command to add a single line to your bashrc file:
您可以通过运行以下命令将该位置添加到您的路径中，以在您的 bashrc 文件中添加一行：
echo 'export PATH=$PATH:/usr/local/bin' >> $HOME/.bashrc
