pip がエラー吐く！ SSL が何とか言ってるけど... (windows環境)

同じエラーにあってる方がいるようで、私はこれで解決しました、というのをいくつか試しました。

• python を入れなおす
• pip を入れなおす
• libsslのなんかのdllをpathの上位のほうに持ってくる

私が解消したのは、「OpenSSL 単体を入れなおす」でした。
本家、https://slproweb.com/products/Win32OpenSSL.html からとってきました。lite版とfullがありますが、うちは、liteで行けました。

python 入れ直しとかよりも簡単と思いますのでお試しあれ...
