I have an install script that I've been using (and I swear it worked before on another Pi), but whatever I've done, it appears I have a broken install of pip, and I'm not sure how to fix it.
I tried several packages (pymodbus, simplejson), and both produce the following errors:
pi@raspberrypi:~ $ sudo pip install pymodbus Downloading/unpacking pymodbus Cleaning up... Exception: Traceback (most recent call last): File "/usr/lib/python2.7/dist-packages/pip/basecommand.py", line 122, in main status = self.run(options, args) File "/usr/lib/python2.7/dist-packages/pip/commands/install.py", line 290, in run requirement_set.prepare_files(finder, force_root_egg_info=self.bundle, bundle=self.bundle) File "/usr/lib/python2.7/dist-packages/pip/req.py", line 1178, in prepare_files url = finder.find_requirement(req_to_install, upgrade=self.upgrade) File "/usr/lib/python2.7/dist-packages/pip/index.py", line 194, in find_requirement page = self._get_page(main_index_url, req) File "/usr/lib/python2.7/dist-packages/pip/index.py", line 568, in _get_page session=self.session, File "/usr/lib/python2.7/dist-packages/pip/index.py", line 694, in get_page req, link, "connection error: %s" % exc, url, TypeError: __str__ returned non-string (type Error)
I tried reinstalling pip with
sudo apt-get install --reinstall python-pip (including purging & autoremove), and tried installing pip using
sudo easy_install pip; and tried using pip to upgrade itself (
pip install -U pip), but none of these things fixes the problem (and in fact the 3rd one throws the same error).
Does anybody have any ideas for me to try here? I feel like I'm missing something obvious, but can't put my finger on it.
