仮想環境構築でmatplotlibがインストール出来ない！

Last updated at Posted at 2019-12-23

matplotplibが入らない！！！

実務作業で仮想環境の構築が必要になった・・・でも、

pip install -r requirement.txt

でエラーログが出てくる...

概略

いろいろ試しましたが、結果的には、requirement.txtに入っているライブラリのバージョンと、インタプリタとして使ったpythonのバージョンが違っただけのことでした。

以下、自分の争いの痕跡です。

正当な解決方法はこちらに示しましたので、時間が無い方は先に見てください。

WARNING: You are using pip version 19.2.3, however version 19.3.1 is available.
You should consider upgrading via the 'python -m pip install --upgrade pip' command.

お決まりのpipアップグレードしてってやつと、どうやらMatplotlibがどうちゃらこうちゃら、よくわからん。。。

いろいろ調べたら、どうやら.whlファイルってのが存在していないらしい（参考:Install Matplotlib on Windows10 machines）。

リンク先の解法では、pip install nameof.whlで解決できるよって書いてあったけど、業務上勝手に仮想環境を変えるのはよろしくない。。。

ここで筆者環境にも書いたけど、pythonの32bit版を入れていたことに気づいた。本家インストーラーを使うと、32bit版が勝手にインストールされるらしい。32bitの方が安定らしい（？）けど、64bit版を要求するライブラリもあるらしい（？）(参考:Pythonの32ビット版と64ビット版について（Windows）)

なので、急遽pythonを64bit版の3.8にしてみることにした

試してみたこと1:pythonを64bit版にする。

公式サイトインストーラーから、pythonの64bit版、バージョンは、3.8をダウンロード。32bit版はアンインストールし、さらにPycharmのインタープリターも、64bit版に変更。

結果1:pythonを64bit版にしてみる。

効果なし。エラー内容に変化がなかった。

試してみたこと2:pipをアップグレードする。

python -m pip install --upgrade pipでpipのバージョンを最新のものにした。

結果2:pipをアップグレードする。

効果なし。

試した見たこと3:WSLでpyenvを使ってPython3.6.6をインストール

Windows SubSystem for Linuxと呼ばれる機能を使って、pyenvをインストールしました。pythonのバージョン管理のためのものです。このrequirement.txtはpython3.6.6で作られたらしいので、それでインストールしてみました

結果3:WSLでpyenvを使ってPython3.6.6をインストール

成功しました。でも、このままじゃPycharmを使った作業が出来ないです...

試してみたこと4:Python3.6.6と3.8.1をWindows内で共存、管理する

別の記事に書いたので、こちらを御覧ください

結果4:Python3.6.6と3.8.1をWindows内で共存、管理する

もちろん、成功しました。

考察

requirement.txtに乗っているライブラリのバージョンにあったpythonのバージョンを用いるべきだということですね。こんな初歩的なことだったとは...
