現在、Ubuntu 16.04 に python パッケージ pylearn2 をインストールしようとしています。オンラインで、次のように機能する2つのアプローチを見つけました。
sudo pip install git+git://github.com/lisa-lab/pylearn2.git
そしてこのように：
git clone git://github.com/lisa-lab/pylearn2.git
cd ./pylearn2/
python setup.py develop
ただし、どちらも機能しません。最初のアプローチでは、出力として次のようになります。
The directory '/home/myUser/.cache/pip/http' or its parent directory is not owned by the current user and the cache has been disabled. Please check the permissions and owner of that directory. If executing pip with sudo, you may want sudo's -H flag.

この後、pylearn2 のインストールまたはエラーに関するメッセージが表示されると思いますが、どちらも発生しません。2 番目のアプローチではエラーが発生します。

ここで何がうまくいかないのかについて、より多くの洞察を持っている人はいますか?
