Plotsが使えない！
using Plotsをしても, GRのインストールがちゃんとできてないとか言って
エラーがでた. 前の日まではなんの問題もなく使えてたのに.
具体的には以下のメッセージ

Your GR installation is incomplete. Rerun build step for GR package.
ERROR: LoadError: LoadError: InitError: Evaluation into the closed module `GR` breaks incremental compilation because the side effects will not be permanent. This is likely due to some other module mutating `GR` with `eval` during precompilation - don't do this.

GRやPlotsを入れ直したり, Pkg,gc()など色々しても無駄だったけど,
using GRをしてみたら, 勝手に修復しますとかいって修復してくれた.
そして解決.
