I am attempting to install the openstack nova client on my Mac (10.4.8)
nova = https://github.com/openstack/python-novaclient#command-line-api
python --version
Python 2.7.2
I successfully got nova installed (after installing pip)
When I run the client, I get the following error
foo#bar-macbook-pro:~$ nova
Traceback (most recent call last):

ImportError: No module named pbr.version
In my research, I have found conflicting information about pbr, some say it is required for nova, while others say it isn't required for nova.

When I attempt to install pbr, I see the following error.

Is there anything apparent that would explain why I can not get the library installed?
Surely I must not be the first person to try and install nova on OS X.
Over a year later, I finally got this working on OS X Yosemite
sudo pip install python-novaclient
I did not have to install pbr.
I did the install based on venv:
virtualenv venv_name
source venv_name/bin/activate
pip install python-novaclient fabric
In my case, I had a mixup in which python I was using by way of fabric being installed globally.
Prior: rf -rf all my virtualenvs, rf -rf all references to novaclient (locally, and globally), and deleted a global install of fabric which was calling the novaclient.
Also as a precaution, I do not install pip globally, and only use it without sudo in virtualenvs.

I might have multiple problems here but they both deal with virtualenv and python3 (3.6.13).
Problem 1:
I had installed virtualenv==20.14.1.
However, it's complaining that there's a version conflict for some reason.
$ python3 -V
Python 3.6.13
$ virtualenv -h

Problem 2:
I downgraded virtualenv to be 15.0.1 like it said it needed but then it complains that there's a missing module called dataclasses. For some reason, my co-workers don't have this problem but we can't figure out what is different between my setup and their setup.

This seems to be a chicken and the egg problem. I would run pip to install this missing module but pip is the program that is complaining about this missing module so I can't install it. Like I said above, none of my co-workers I asked know what the problem is.
For debugging purposes, I installed python 2.7.12 and virtualenv==20.14.1 to see what would happen. Apparently things work fine with python 2.7.

So the questions are
Why do I need to use virtualenv 15.0.1? Why can't I use a newer version of virtualenv?
How come python3 is complaining about the missing dataclasses module but python2 is ok?
Like mentioned in this pypi docs; https://pypi.org/project/dataclasses/ dataclasses only exist in 3.7 and above, which i would recommend to use instead, otherwise, you could also download this package in hopes that it fixes your problem. Are you limited to a python version?

Using an administrator command prompt doesn't help. My real goal is to get win32com working under arcpy. I usual just copy the appropriate directories out of c:\python27\lib\site-packages to c:\python27\arcgis10.2\lib\site-packages to install a package under arcpy (why doesn't arcpy come with pip?) but that's not working for win32com, presumably do to a missing dll or other windows specific file.
I would recommend the following:
Get the setuptools module
Get the pip module`
And then run the following in command line (assuming windows)
path-to-python path-to-setuptools install
path-to-python path-to-pip install
I work on a closed network (away from the interwebs of old) and cannot use get-pip.py so I find it best to simply download the actual modules and hard install.
Keep us posted!
Copy get_pip.py to "C:\Python27\ArcGIS10.2", then perform command "python get-pip.py" in the directory.
Note that keep network connected in the process, so that auto-download and setup setuptools,wheels,etc.
Hope that can help you.
Try opening a CMD prompt and typing:
C:\Python27\ArcGIS10.2\python.exe -m pip install -U pip
I'm trying to load test my MQTT network on a CentOS7 machine by using this repositorie on github. I executed the following commands to install the python-mosquitto dependency.
# yum install python-pip
# pip install mosquitto
Then I built and installed the setup.py file located in the repository file:
# python setup.py build
# python setup.py install
When trying to use the package, an error was thrown:

EnvironmentError: Unable to find libfuse
Googling the error didn't provide me any answers. Did I do something wrong in the install process? I don't have much experience with the usage/building of cloned Github Repositories.
If running CentOS you may want to do "yum install fuse-python", which will install fuse-libs as dependencies. It worked for me after doing that.
The issues page on the repository (the issue right before the one you linked to) mentions exactly this problem.
The solution, as you've found is to install fusepy separately, either from your package manager or with pip install fusepy.

You need to install tesseract-ocr:
sudo apt-get install tesseract-ocr
If you're on windows and have PIP installed go to your project directory and run:
pip install tesseract-ocr
Based off of #padraic cunningham's answer which I tailored to my setting.
If you are on Linux (ubuntu 16, should not matter) and have a conda installation:
First search for what you need to be installing:
$ anaconda search -t conda tesserocr
You will get a few options, you need to look at the platforms and builds to identify what makes sense for you.
As I have python 3.6 and linux-64 I chose mcs07/tesserocr
To install:
$ conda install -c mcs07 tesserocr
That's it. I didn't need a restart of the terminal or anything. I just kept going.

ImportError: No module named pylons.util
I'm not sure how to proceed, any ideas?
ImportError: No module named pylons.util looks like Python cannot find the Pylons package, one of the Python packages that CKAN depends on. Two possibilities come to mind:
Did you activate your CKAN virtualenv, before running the paster command? ~/ckan/default/bin/activate.
Have you installed the Python packages that CKAN depends on into your virtualenv? With the virtualenv activated run pip install -r ~/ckan/default/src/ckan/requirements.txt
If you activate your CKAN virtual environment and then run pip freeze | grep pylons, this should tell you whether pylons is installed in the virtualenv.
The Distribution already installed: at the top of your terminal output is strange.
I had the same error and a slightly different solution:
got the error only after using sudo, so I went out of it (sudo -k)
then I got the following error: IOError: [Errno 13] Permission denied: '/etc/ckan/default/development.ini'
after digging around a lot, I finally found out that while the /etc/ckan had correct permissions, it was actually a symlink to ~/ckan/etc and that folder did not have correct permissions
I ran sudo chown -R `whoami` ~/ckan/etc and followed up with paster make-config ckan /etc/ckan/default/development.ini
