rvm関連
Unknown ruby interpreter version (do not know how to handle): hoge.
=> （原因）rvm use hoge --defaultを実行
すでにgemsetの名前にhogeが設定されているものだと思ってた。
=> （解消）rvm use 2.0.0-p648@hoge --defaultを実行
YAML safe loading is not available. Please upgrade psych to a version that supports safe loading (>= 2.0).
=> （原因）Railsのpsychというgemのバージョンが古い？
=> （解消）この辺やったようなやってないような。

Warning: can not check /etc/sudoers for secure_path
Warning: can not check `/etc/sudoers` for `secure_path`, falling back to call via `/usr/bin/env`, this breaks rules from `/etc/sudoers`. Run:
export rvmsudo_secure_path=1
to avoid the warning, put it in shell initialization file to make it persistent.
In case there is no `secure_path` in `/etc/sudoers`. Run:
export rvmsudo_secure_path=0
to avoid the warning, put it in shell initialization file to make it persistent.

RVM: Ruby Version Manager - Upgrading RVM
Warning! PATH is not properly set up, '/usr/local/rvm/gems/ruby-2.4.1/bin' is not at first place.
Warning! PATH is not properly set up, '/usr/local/rvm/gems/ruby-2.4.1/bin' is not at first place.
Usually this is caused by shell initialization files. Search for 'PATH=...' entries.
You can also re-add RVM to your profile by running: 'rvm get stable --auto-dotfiles'.
To fix it temporarily in this shell session run: 'rvm use ruby-2.4.1'.
To ignore this error add rvm_silence_path_mismatch_check_flag=1 to your ~/.rvmrc file.
=> （原因）rvmsudo rvm gemset create hogeしたらデフォルトのRuby2.4.1に紐づいた。
=> （解消）rvm use ruby-2.0.0してからやる。
you can switch to '.ruby-version' using 'rvm rvmrc to ruby-version'
You are using '.rvmrc', it requires trusting, it is slower and it is not compatible with other ruby managers, you can switch to '.ruby-version' using 'rvm rvmrc to ruby-version' or ignore this warning with 'rvm rvmrc warning ignore /home/ec2-user/environment/.rvmrc', '.rvmrc' will continue to be the default project file in RVM 1 and RVM 2, to ignore the warning for all files run 'rvm rvmrc warning ignore all.rvmrcs'.
=> （原因）.rvmrcファイルにRubyのバージョンを固定して、新しいターミナルを開いたら.rvmrcファイルは古いから新しくしろとエラー。
=> （解消）rvm rvmrc to ruby-versionした。

bundle installを実行すると以下のエラーが発生する
The dependency tzinfo-data (>= 0) will be unused by any of the platforms Bundler is installing for. Bundler is installing for ruby but the dependency is only for x86-mingw32, x86-mswin32, x64-mingw32, java.

Resolving dependencies...
Bundler could not find compatible versions for gem "activesupport":
In snapshot (Gemfile.lock):
activesupport (= 5.1.6)
In Gemfile:
rails (= 5.1.4) was resolved to 5.1.4, which depends on
activesupport (= 5.1.4)
coffee-rails (= 4.2.2) was resolved to 4.2.2, which depends on
railties (>= 4.0.0) was resolved to 5.1.6, which depends on
activesupport (= 5.1.6)
Running `bundle update` will rebuild your snapshot from scratch, using only
the gems in your Gemfile, which may resolve the conflict.
=> （原因）bundle installをすると、 bundle updateをしていないという警告が走る。
=> （解消）bundle updateを実行してから、bundle installを実行する。
