cloudstorageのInstall Packageエラー(PyCharm)

Question

◆起こっている事象
PyCharm環境で「cloudstorage」を手動インポートしたところ
「command 'C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\BIN\x86_amd64\cl.exe' failed with exit status 2」となりエラーとなりました。
解決策を教えてください。

◆実際にやったこと
PyCharm起動 > File > Setting > Project Interpreter > Project Interpreter:Python3.6 >+ボタン > cloudstorageを検索 > Install Package > エラー発生

◆Command output
Command outputを見る限りxattr.hのインクルードで失敗しているみたいです。

Extended attributes are currently only available on Darwin 8.0+ (Mac OS X 10.4) and Linux 2.6+. Experimental support is included for Solaris and FreeBSD.

Metadata and other attributes are saved as extended file attributes using the package xattr. Extended attributes are currently only available on Darwin 8.0+ (Mac OS X 10.4) and Linux 2.6+. Experimental support is included for Solaris and FreeBSD.

依存パッケージのxattrがWindowsでは動かないですね。
該当する機能がWindowsにないからxattr.hがないのも当然かと。

cloudstorage を fork して自分で直して、依存性と Local File System Driver を削除しないとインストールできないでしょう。
