pip install numba のエラーを解決したい。

前提・実現したいこと

pipを用いてnumbaのインストールを行いたいです。
いつもどおり

pip install numba

を実行したところ、大量のエラーが出たため、
こちらhttps://www.jkawamoto.info/blog-ja/install-numba-to-mac/のサイトを参考に、
numbaのインストールを行おうとしました。
しかし、

brew tap homebrew/versions

のコードで

Error: homebrew/versions was deprecated. This tap is now empty as all its formulae were migrated.

のエラーが出てしまい、先に進めないです。
上のエラーの解決方法もしくは、何か他にnumbaをインストールする方法があれば教えていただきたいです。

pip install numbaエラー

WARNING: pip is being invoked by an old script wrapper. This will fail in a future version of pip.
Please see https://github.com/pypa/pip/issues/5599 for advice on fixing the underlying issue.
To avoid this problem you can invoke Python with '-m pip' instead of running pip directly.

brew tap homebrew/versionsエラー

Error: homebrew/versions was deprecated. This tap is now empty as all its formulae were migrated.

試したこと

brew tap homebrew/versionsエラーの対処として、
こちらhttps://github.com/mrirecon/homebrew-bart/issues/1を参考に、

brew tap homebrew/homebrew-core

実行しましたが、この先からどうすればいいのか分からなくなりました。

補足情報（FW/ツールのバージョンなど）

macOS 10.15.4
python3.5(仮想環境を作って実行しています。)

よろしくお願いします！

まず、LLVM (Python のライブラリではない。)をインストールする必要がありそうです。 Mac での事情は分からないので次のページなどを参照してください。 Clangのインストール | 学生たちの技術ブログ https://students-tech.blog/post/install-clang.html#clang%E3%81%A8%E3%81%AF

ご回答ありがとうございます！！ llvmを入れる必要があるいうのはネットでみつけて、[brew install llvm]を実行して最新版を入れたのですが、そのあとの[pip install numba]ではエラーになってしまいインストールできませんでした。 llvmのバージョンが最新の 3.8.x ではなく 3.7.x が必要だと一番上に貼ったサイトに書いてあり、それを参考に[brew tap homebrew/versions]を実施したのですがそれもまたエラーでした。もう少し方法を探してみます、ありがとうございます！

Windows の場合だと llvm-config が、インストーラーではインストールされないらしくて、Visual Studio で Debug でビルドするように書いてあるページがありました。まだ、こちらではうまくビルドできてないですけど。

githubから落としてきたコードを動かす際に、pip install numbaの手順が書かれていたので行いたかったのですが、とりあえずnumbaをインストールせずに進めてみたところ、コードを動かすことができました。ご協力いただきありがとうございました！！！
