自分で作った？ ？エラー：--no-user-cfgオプションが認識されません。

技術のないホームブリッジを使用してSnow Leopardでcmakeを更新しました（avidemuxインストールの一部として...）。

 $brew -v upgrade cmake 

すべて正常に進行

Verifying cmake--markupsafe-0.23.tar.gz checksum

これにより、次の行の後にエラーが発生します。

==> python -c import setuptools... --no-user-cfg install --prefix=/private/tmp/cmake-lwlJTD/cmake-3.1.0/sphinx --single-version-externally-managed --record=installed.txt
usage: -c [global_opts] cmd1 [cmd1_opts] [cmd2 [cmd2_opts] ...]
   or: -c --help [cmd1 cmd2 ...]
   or: -c --help-commands
   or: -c cmd --help

error: option --no-user-cfg not recognized

残念ながら、私はいくつかのコマンドが省略されているように見えるので、--no-user-configオプションが何であるかわかりません。 Google検索は無関係なさまざまな結果を提供します。

私はそれがPythonの問題だと思いました。

$brew -v upgrade python
Homebrew 0.9.5
Error: python 2.7.9 already installed
Kernel.exit

この問題を解決するにはどうすればよいですか？
