Created git commit.
Success! Created awesome-project at /Users/ユーザー名/React/awesome-project
Inside that directory, you can run several commands:
npm start
Starts the development server.
npm run build
Bundles the app into static files for production.
npm test
Starts the test runner.
npm run eject
Removes this tool and copies build dependencies, configuration files
and scripts into the app directory. If you do this, you can’t go back!
We suggest that you begin by typing:
cd awesome-project
npm start
Happy hacking!

4. React プロジェクトの実行
% cd awesome-project
% npm start
「awesome-project」フォルダの中に入り、コマンド「npm start」を実行します。
ターミナルの表示が下記に変わり、ブラウザが起動します。
Compiled successfully!
You can now view awesome-project in the browser.
Local: http://localhost:3000
On Your Network: http://192.168.3.3:3000
Note that the development build is not optimized.
To create a production build, use npm run build.

==> Caveats
A CA file has been bootstrapped using certificates from the system
keychain. To add additional certificates, place .pem files in
/usr/local/etc/openssl@1.1/certs
and run
/usr/local/opt/openssl@1.1/bin/c_rehash
openssl@1.1 is keg-only, which means it was not symlinked into /usr/local,
because macOS provides LibreSSL.
If you need to have openssl@1.1 first in your PATH run:
echo 'export PATH="/usr/local/opt/openssl@1.1/bin:$PATH"' >> ~/.zshrc
For compilers to find openssl@1.1 you may need to set:
export LDFLAGS="-L/usr/local/opt/openssl@1.1/lib"
export CPPFLAGS="-I/usr/local/opt/openssl@1.1/include"
