pyenvにAnaconda系バージョンを入れるとPipenvの初期化に失敗する

LegacyVersion('anaconda3-5.3.1')というエラー

% pipenv --three
Traceback (most recent call last):
  File "/usr/local/lib/python3.7/site-packages/pipenv/vendor/pythonfinder/models/pyenv.py", line 53, in get_versions
    version = PythonVersion.parse(p.name)
  File "/usr/local/lib/python3.7/site-packages/pipenv/vendor/pythonfinder/models/python.py", line 119, in parse
    raise ValueError("Not a valid python version: %r" % version)
ValueError: Not a valid python version: <LegacyVersion('anaconda3-5.3.1')>
...

こんなエラーが出た。LegacyVersion('anaconda3-5.3.1')らしい。

Anaconda installer archiveによると2018-11-19リリース版。なのにレガシー。

そもそもAnacondaは使ってない

% python --version
3.7.3

% which python
/Users/user/.anyenv/envs/pyenv/shims/python

デフォルトは現在最新の3.7.3を有効にしている。anacondaは使ってない。

このanaconda、どこから来たのか。

複数環境をスイッチさせてる中にanacondaを入れるとよくないという話を聞くが、こういうことが起こるからだろうか。

アナコンダは気質に悪評があり、さらにオオアナコンダは大きすぎるので、ボアと比べるとペットとしては人気がない。

アナコンダ - Wikipedia

ペットでもアナコンダは人気無いようですし（関係ない）。

pipenv --python `which python`で動く？

手探りしてたら、pipenvの初期化でパスが通ったpythonのバージョンを指定したら通った。

この指定で動くのも、また謎すぎる。

Using base prefix '/Users/user/.anyenv/envs/pyenv/versions/anaconda3-5.3.1'というログが残ってるから、強引に置き換えて無理やり動かした感じがする。

やっぱり動かない

% pipenv shell

pipenv shellをすると警告が出た。いちおう、shellには入れる。

(sandbox) % pipenv install requests

installが使えないので、やはり正常にインストールされてなかった。

Anacondaを消してみる

Anacondaを消して、再度pipenvしてみる。

% pyenv uninstall anaconda anaconda3-5.3.1
pyenv: remove /Users/user/.anyenv/envs/pyenv/versions/anaconda3-5.3.1? y

% pyenv versions
  system

% rm .venv

動いた。

Anacondaが最新だったら

Anacondaが古いからダメなのかもしれないと思い、最新のAnacondaを入れて、再度pipenvをしてみる。

% pipenv --three

    raise ValueError("Not a valid python version: %r" % version)

やはりエラーになる。LegacyVersionって、それ現在の最新版ですよ！

どうやらpyenvにAnacondaを混ぜるとよくないらしい。

ビルドインのpipenvを使わなければ動く

pyenvで入れたPythonにPipenvをインストールすれば動く。

% which pipenv
/usr/local/bin/pipenv

% pip install pipenv
...

% which pipenv

今までPipenvはMacのビルドイン版を使ってたけど、こっちのほうがいいのかな。
