Docker for Macではここの処理は正常に完了するのにWindowsがホストの場合にこのエラーがでます。 色々調べた結果おそらく、下記のいずれかが原因だと思うのですが対処方法がわかりません。

• WinsowsのPathの最大長制限(260文字)に引っかかっている
• ホストOSがWindowsの場合、シンボリックリンク(symlink)をサポートしていない

WinsowsのPathの最大長制限を解除するためのグループポリシーの設定変更で「Win32の長いパスを有効にする」を有効にしてみても事象は改善されないので、やはりWindowsがsymlinkにサポートしていない、というのが原因のようです。

どなたか対処方法がわかったら教えてください。
