+If you are a Mac user, you might have some trouble with `virtualenvwrapper` because of the differnt setting of your python. The guide we provided above include more information on how to set it up properly, and you can also look at [this page](https://stackoverflow.com/questions/49470367/install-virtualenv-and-virtualenvwrapper-on-macos) to troubleshoot. Using `pipenv` might be simpler if you failed to get `virtualenvwrapper` working.

+* After you install the homebrew, you should make sure you also installed the `wget` on your machine. You can do it through command `brew install wget`.
