scrapyは、私は窮地ページはなど、サブドメインに下線含まれてみてください

Question

を強調しています。 また、私はlink.encode（ 'idna'）を試してみましたが、動作しませんでした。

と私はエラーがあります：それはツイストとの問題だよう

は思えます。それhereに関するソリューションとの問題があります

：

Looking at Twisted's code, it'll use the ​idna library if available. If I pip uninstall idna and issue the same request again, it is successful.

idna gets installed with either pip install twisted[tls] or pip install treq.

私はpip uninstall idnaと要求を介しIDNAをアンインストールしようとしましたが、確かに、通り抜けます。
