[RUBY] Where I got stuck in today's "rails tutorial" (2020/10/04)

Introduction I started the rails tutorial today. I will leave a memorandum on Qiita so that I can look back on where I am stuck. It's my first time to write in Qiita & markdown notation, so I would appreciate it if you could point out any difficulties in writing. Basically, the environment follows the rails tutorial and uses Cloud9.

Clogged place

1.2.1 Development environment -Event: When registering Cloud9, a setting screen that is not described in the rails tutorial is displayed. -Solution: There is no problem registering with the default.

1.3.2 rails server

-Event: After executing [rails server], even if I click [preview running application], the connection is refused and the page is not displayed in the browser. -Solution: It was possible to display it by clicking [Pop out in new window] on the upper right to make it a separate window. ![image.png](https://qiita-image-store.s3.ap-northeast-1.amazonaws.com/0/764452/844943e5-d8d8-bd1a-1151-e135ae37e2a8.png)

Today's summary ・ Progress: Chapter 1 1.1-1.3 read ・ Date: 2020/10/04 (Sun) 13: 00-16: 00

・ Impression: I started with a jerk because I saw the wording that pre-learning by Progate was required, but since I was studying the basics of html, css, JS, UNIX commands, etc. in dot installation, I was able to avoid the situation of stumbling on the introduction. .. I don't know anything about Ruby, so if I get stuck I'll rely on dot install.

I can concentrate on studying at the P.S. cafe, but it is very difficult to be unable to move. You may need to find an environment where you can go and come back somewhere along the way. Also, working on a laptop is bad for your neck, so you should consider buying a stand early.
