Qiitaの使い方、プログラムからの利用
https://qiita.com/kaizen_nagoya/items/86dfcd81dd99d9e57021

にあげた事項を順にやろうとして挫折。
3台のMacを利用。

原因は

1 brewの導入がユーザ依存
機材によってbrewの管理IDが違う
2 python2と3の管理が不十分
python2中心の機材とpython3中心の機材あり
3 pipが未導入の機材があった
python2のpipが未導入
4 DHCP, DNSの設定がサーバと端末で不整合
　午前１時間、午後１時間、wiresharkで測定。
　ARPの応答がなく、DNSがひけてない。
別機材（ルータ）経由で接続
　一部は無線代替。

==> Caveats
This formula is keg-only, which means it was not symlinked into /usr/local,
because macOS already provides this software and installing another version in
parallel can cause all kinds of trouble.

If you need to have this software first in your PATH run:
  echo 'export PATH="/usr/local/opt/curl/bin:$PATH"' >> ~/.bash_profile

For compilers to find this software you may need to set:
    LDFLAGS:  -L/usr/local/opt/curl/lib
    CPPFLAGS: -I/usr/local/opt/curl/include
For pkg-config to find this software you may need to set:
    PKG_CONFIG_PATH: /usr/local/opt/curl/lib/pkgconfig
