I've just installed Python 3.5 from the source tarball and received an unexpected error related to pip. On Linux, as a regular user (except for the last line):
wget https://www.python.org/ftp/python/3.5.2/Python-3.5.2.tgz tar xvf Python-3.5.2.tgz cd Python-3.5.2 ./configure make sudo make altinstall There were no obvious errors until the end: The directory '/home/steve/.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. Ignoring indexes: https://pypi.python.org/simple The directory '/home/steve/.cache/pip' or its parent directory is not owned by the current user and caching wheels has been disabled. check the permissions and owner of that directory. If executing pip with sudo, you may want sudo's -H flag. Can anyone explain what is going on, why I should care, and how I should fix it? -- Steve “Cheer up,” they said, “things could be worse.” So I cheered up, and sure enough, things got worse. -- https://mail.python.org/mailman/listinfo/python-list
