私の今日は、Pythonがプリインストールされた新鮮なUbuntuの16.04をインストール：マニュアルページhttp://doc.scrapy.org/en/latest/intro/install.htmlに述べたようにScrapyセットアップUbuntuは16.04または任意の他の
[email protected]:~$ python --version
Python 2.7.11+
[email protected]:~$ python3 --version
Python 3.5.1+
私は、このリンクhttp://doc.scrapy.org/en/latest/topics/ubuntu.html#topics-ubuntuを開き、Scrapyをインストールするために説明されている手順に従ってみました。
しかし、私はステップ3
sudo apt-get update && sudo apt-get install scrapy
後にエラーが出る...
The following packages have unmet dependencies:
scrapy : Depends: python-support (>= 0.90.0) but it is not installable
Recommends: python-setuptools but it is not going to be installed
E: Unable to correct problems, you have held broken packages.
私はScrapyとエラーに関する昨日の問題を投稿し、それはあまりにもが、Windows上でのセットアップの問題だったように見えます。 Cannot setup Scrapy on windowsだから私はUbuntuでもう一度やり直してみました。
Ubuntu 16.04でScrapyを設定するにはどうすればよいですか、それとも他のバージョンかもしれませんか？古いScrapyのマニュアルのようです。私はScrapyプロジェクトが死んだと思うだろうが、人々はまだScrapyを使用していることを知っている。 ScrapyはPython 2でのみ動作します+？だから私はWindowsにとどまります。すべてのバリアントを確認することはできません。時間がかかり過ぎる。誰もが安定した設定（オペレーティングシステム+ Pythonのバージョン）と言いますか？
ありがとうございました。
アップデートはここで私は、ドッカーてみました。私は端末からDockerfile、他のステップを作成する：1 があってはならないDockerfileの最初の行のように見える

[email protected]:~$ scrapy version
The program 'scrapy' is currently not installed. You can install it by typing:
sudo apt install python-scrapy
UPDATE。私がそれを取り除くと（$ cat Dockerfile）
私はドッカーのイメージを稼働させることができますが、もう一度ピップをインストールすると幸いです。以上のことより、私はドッカーとの間でいくつかのオーバーヘッドを行う必要があることを認識しています（私はコーディング時にGUIを好みます）。このDockerイメージには何かツールがインストールされていますか？ここにインストールログ：
