試したこと

greenletについて何か問題があるのだと考えたため, 解決方法を調べたところ,
・Pythonを最新にする
・xcode-select --installで, setuptolsをインストールする
などがありました. 全て試しましたが, 状況は変わりませんでした.
pipで他のパッケージを試しにインストールしようとしても, greenletについての同じようなエラーに阻害されました.

補足情報（FW/ツールのバージョンなど）

MacOS BigSur 11.1
NVIM v0.4.4
Python 3.9.1
pip 20.3.3 from /usr/local/lib/python3.9/site-packages/pip (python 3.9)

pynvimをインストールしてみましたが、問題は発生しませんでした。

私のBig Surには、llvmはインストールされていず、/usr/bin/clangが使われています。

回答ありがとうございます. 先程llvmをアンインストールしてきて(完全に消せたかはわかりませんが...)再度試したところ, 無事pynvimをインストールできました.
