How to install Node.js

The latest LTS version of Node.js is recommended.

If none or low version of Node.js is installed, you need install the latest version of Node.js according to the following instructions:

1. For Windows: please visit https://nodejs.org/ to download the latest LTS version of Node.js and then, install it using the default options.

2. For Mac: the same as Windows.

3. For Linux: using package manager to install is recommended, because in this way, you don't need to configure the PATH variable. If you fail, you can also use the binary version of Node.js directly.

   • using package manager: follow the instructions here​

   • using binary version: visit official Node.js website to download the latest Linux Binaries (or using command wget to download), unzip (tar -xzvf node-xxx.tar.gz), add the absolute path of bin directory to system PATH after extracting.

You can execute node -v in shell to check if the expected version of Node.js is installed successfully:

$ node -v
v8.9.4
