after installed dojo/cli, and running dojo command, the programe print "Invalid response from npm search"

Hello, I'm following your website (https://dojo.io/tutorials/001_static_content/), and used npm to install @dojo/cli and @dojo/cli-create-app, the execute command like this :
```shell
#!/bin/bash
npm install -g @dojo/cli
npm install -g @dojo/cli-create-app
dojo create app --name first-dojo-app # right here, the program noticed npm install error, and just exit, the error msg notice because dojo-interface was deprecated, so install is not totally finish, so i use yarn to install
cd first-dojo-app
yarn # instead of not full npm install
dojo build -m dev -w memory -s
# after execute this command, the dojo print "Invalid response from npm search" info, but i don't know where the invalid response is, and what the invalid content is
```

This is my system info and npm,node env version:
1, node v8.4.0
2, npm v5.3.0
3, Ubuntu 16.04.2 LTS
4, yarn v1.1.0

Is that system environment not satisfield? Should I need to release version? Or change the npm source url? Or dojo cli tools is not compatible with the Linux system?

I wanna to use dojo, and wanna study by dojo website, but cannot success create app step by step, could you help, Thanks a lot

Reproduce the tutorial flow with the listed Node.js, npm, Yarn, and Ubuntu versions, starting with `dojo create app --name first-dojo-app` and then `dojo build -m dev -w memory -s`. Trace the npm search response behind the reported message; done means identifying the compatibility or response failure and making the documented app-creation flow complete successfully.
