【教えてください】toolchain build kivyの実行について

Question

前提・実現したいこと

今、pythonを用いてkivy-iosをコマンドで作成しています。
そこで、以下のようにcythonまでの流れはうまくいっています
$ python3 -m venv venv
$ . venv/bin/activate
$ pip3 install kivy-ios
$ brew install autoconf automake libtool pkg-config
$ brew link libtool
$ pip3 install cython

ここからtoolchain build kivyで通常15-20分くらいの各種ダウンロードが起こるそうですが、
以下のようなメッセージが出て、すぐに空ファイルができてしまいます。

発生している問題・エラーメッセージ

出ているエラーは 
return func(*args, **kwargs)
ValueError: read of closed file
で空のbuildとdistファイルができるのみでダウンロードの実行が起こりません。

該当のソースコード

python

$ toolchain build kivy

試したこと

よくわからず、上記のこと以外は試せていません。

補足情報（FW/ツールのバージョンなど）

特にありません。

タグに「Kivy」を追加する方がいいのではないですかね

[JNBa]

ありがとうございます。タグはどこにつけると良いでしょうか？

[jbpb0]

現状この質問には「Python」「ファイル」「コマンド」「pip」「ダウンロード」というタグが付いてますけど、それはこの質問を作った時に質問者さんが選んで付けたのですよね？？
それに追加するのです

[JNBa]

アドバイスありがとうございます。Kivyを追加させていただきました。

[jbpb0]

https://github.com/kivy/kivy-ios
の「Using the toolchain」には

toolchain build python3 kivy

って書かれてますけど、「python3」って付けなくてもいいのでしょうか？

Kivyはよく知らないので、外してたらごめんなさい

[JNBa]

アドバイスありがとうございます。

toolchain build python3 kivyも試しましたが、上記のerrorと同様でした。

引き続き、ご教示のほど、どうぞ宜しくお願いいたします。

[jbpb0]

xcode-select --install

は、やりました？

[JNBa]

jbpb0さん、いつもありがとうございます。

先程は記載しておりませんでしたが、xcode-select --installも行っております。
また、XcodeもAppにダウンロードしております。

引き続き、ご教示のほど、どうぞよろしくお願いいたします。

[jbpb0]

toolchain recipes

を実行したらずらーーーっと表示される中に「freetype 2.5.5」というのがあったら、
https://download.savannah.gnu.org/releases/freetype/
には「freetype-2.5.5.tar.bz2」が無いので、

toolchain build python3 kivy

の実行時にダウンロードできず、

[INFO ] Download freetype
[INFO ] Downloading http://download.savannah.gnu.org/releases/freetype/freetype-2.5.5.tar.bz2
Traceback (most recent call last):

みたいに表示されます

もし上記の通りなら、
venv/lib/python3.*/site-packages/kivy_ios/recipes/freetype/__init__.py
の「version = "2.5.5"」を、上記Webサイトに存在してるバージョンに書き換えて下記を実行したら、たぶん次に進めると思います

toolchain clean freetype
toolchain build python3 kivy

[JNBa]

jbpb0 様

いつもアドバイスいただき、ありがとうございます。
早速試させていただきます。また結果をご報告させていただきます。
引き続き、どうぞよろしくお願いいたします。

[JNBa]

jbpb0様

以下のように実行しましたが、エラーが出てきました。

に、ファイル名の末尾が「bz2」のファイルが存在するバージョンじゃないとダメです
現時点では、「2.10.0」までですね

【追記】
venv/lib/python3.*/site-packages/kivy_ios/recipes/freetype/__init__.py
の「url = "http://download.savannah.gnu.org/releases/freetype/freetype-{version}.tar.bz2"」の「bz2」を「gz」または「xz」に変えたら、「2.10.0」よりも新しいのが指定できるかも
(未確認)

[jbpb0]

公式の修正は、バージョンを変更するのではなく、バージョンはそのままで下記のようにダウンロードのURLを変えるようなので、そちらに合わせる方がいいかも
https://github.com/kivy/kivy-ios/pull/632/files/d43ba1a98e6e6d6580fdfcc4da3d2e5d517040ee

[jbpb0]

上記をちゃんとやれば(実際に存在するURL・バージョン・ファイル名に合わせる)、解決すると思うのですが、まだ解決してないのでしょうか？

Answer 1

Downloading http://download.savannah.gnu.org/releases/freetype/freetype-2.5.5.tar.bz2

/releases/freetype/
に「freetype-2.5.5.tar.bz2」が無いので、エラーになります

仮想環境名/lib/python3.*/site-packages/kivy_ios/recipes/freetype/init.py
の「version = "2.5.5"」を、上記Webサイトに存在してるバージョンに書き換えて下記を実行したら、次に進めると思います

toolchain clean freetype
toolchain build python3 kivy

ただし、書き換えるバージョンは、上記Webサイトに、ファイル名の末尾が「bz2」のファイルが存在するバージョンじゃないとダメです

あるいは、公式の修正
Fix outdated freetype url #632
のように、バージョンは変更せずに「2.5.5」のままで、ダウンロードのURLを変えるという対策方法もあります

私も質問者と同じエラーが出てしまいます。init.pyを公式の修正通りにしてtoolchain clean freetypeとtoolchain build python3 kivyを実行すると下記のエラーが出ます。どうすればよろしいでしょうか？

lukeRさん

これ見てください
https://teratail.com/questions/357006

【追記】
ファイルを落とす時のURLが「https:」ではなく「http:」ならssl使わないので、そのエラーが出なくなるかもしれません

公式と同じやり方で修正した「__init__.py」の
url = "https://download.savannah.gnu.org/releases/freetype/freetype-old/freetype-{version}.tar.bz2"
の「https:」を「http:」に変えたら、どうでしょうか？

あるいは、公式の変更方法ではなく、私の回答の前半に書いてある、URLを変えずにバージョンを変える方法でやってみるとか
元々のURLも「http:」なので

教えていただいたサイト先の情報で無事解決いたしました。
