Python Scrapy - service_identity（opentype）が動作しておらず、インストールできない

Question

Pythonとlinux初心者が治療を開始しようとしています。 https://doc.scrapy.org/en/latest/intro/tutorial.htmlの指示とコードに従ってください。ユーザーの警告を受け取っています "service_identityモジュールのインストールがありません： '名前を取り込めません。' opentype '

「service_identity」をインストールしようとしましたが、インストールのさまざまな部分で「Requirment already satisfied」両方のPIP3とダウンロードを試み、以下は、PyPI-URLからダウンロードし.whlたファイルからインストールしてください。

のpython 3.5.3をlubuntu 17.04上のVirtualBoxに

Please install it from <https://pypi.python.org/pypi/service_identity> and make sure all of its dependencies are satisfied. Without the service_identity module, Twisted can perform only rudimentary TLS client hostname verification. Many valid certificate/hostname mappings may be rejected.

import scrapy 


class QuotesSpider(scrapy.Spider): 
    name = "quotes"

Answer 1

あなたの問題は、タイプミスと思われます。 qoutesとquotesを使用しています。 oとuを交換してください。また、service_identityの場合はそのような警告です。インストールしたい場合は

pip3 install service_identity --force --upgrade
