【エラー対処】Anacondaをuninstallするためのanaconda-cleanがインストールできない

Last updated at Posted at 2019-09-13

はじめに

大学の研究室で、最初Pythonの環境構築が面倒だったので（おい）
Anacondaをmacに直接installだったのですが
やはりpyenv+pyenv-virtualenvや、dockerでのPython環境にしたいと考え
Anacondaをインストールすることにしました。

参考サイトは
Anaconda3をmacOSから完全にアンインストールする方法です。

エラー発生

以上のサイトを参考にして

conda install anaconda-clean

を行い、anacondaの関連ファイルを一括削除するパッケージを入れようとすると
以下のエラーが発生しました。

 students$ conda install anaconda-clean

大事なのは下の$2$行

RemoveError: 'setuptools' is a dependency of conda and cannot be removed from
conda's operating environment.

で、「setuptoolsがcondaに依存しているから、condaの環境から削除できないよう〜」っていう部分です。

おそらく、PyPIにパッケージをインストールしたときにsetuptoolsをいじった記憶があるのでそれの影響が出ているんだと思います。

対策方法

まず、Anacondaのcondaをアップデートしないといけないようなので
（PyPI, pipでインストールしてしまったsetuptoolsを依存を治す意図？）

 conda update --force conda

で強制アップデートします。

その後

conda install -c anaconda setuptools

でsetuptoolsをインスコします。

そして、最後に

conda install anaconda-clean

をすると、エラーが消えました。
うれしい！
