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:
# malaria publish -P 2 -n 100 -H localhost -s 10
Error:
# malaria publish -P 2 -n 100 -H localhost -s 10malaria publish -P 2 -n 100 -H localhost -s 10

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.

I'm trying to install readthedocs on my local gitlab server and I'm following the guide in the link.
ReadThedocs Guide
Here's the python version and pip version I'm using;
Python3.9
Pip3.9
To run the virtual pip environment, I use the following command.
python3.9 -m venv tutorial-env # I completed the install process with this command.
source tutorial-env/bin/activate # with this command I access the virtual pip environment
my steps in the virtual pip environment;
I run this from the readthedocs installation steps.
(tutorial-env) [redhat#gitlab tutorial-env]$ pip install -r requirements.txt
And no error occurred.
(tutorial-env) [redhat#gitlab tutorial-env]$ python3.9 /home/redhat/readthedocs.org/manage.py migrate
Gave the following error message

However, when I run the python manage.py migrate command in the pip virtual environment, I get the following error message and I can't complete the installation process. What exactly this problem points to?
Thank you for support.
I haven't tried any solutions because I don't understand what is causing the problem.
You are following an outdated and unofficial documentation of Read the Docs (https://read-the-docs.readthedocs.io/en/latest/install.html). The official guide is a lot more updated and uses Docker now, which is easier to setup. Please, read the official guide at https://docs.readthedocs.io/en/latest/development/install.html
I'm trying to configure 2 Ubuntu servers to use Python and Tensorflow for my project. I finished the 1st server, however, there are some very unusual and annoying errors with the 2nd one. This is the log when I run pip check on the 1st server:
~$: pip check
No broken requirements found.
And the error log on the 2nd one:
~$: pip check
No broken requirements found.

This error also shows everytime I'm trying to install a new package with pip. Anyone faced similar problems with pip or having a way to diagnose the error?
EDIT 1:
As languitar suggestion, I ran lsb_release -a on both machines and this is the log on the 1st one:

You did not mention your Python version(s) available on your system.
Not sure how this happen, but often 'lsb_version' is available to run on python v2 and others on v3.
Most likely you have a multiple python version on your host.
subprocess.CalledProcessError: Command 'lsb_release -a' returned non-zero
exit status 1
Is, indeed, failing because the 'lsb_release' library called by '/usr/bin/lsb_release' is not available for your particular Python version.
Your first attempt to fix this is simple:
sudo apt install lsb-release
Note is '-' and not '_'
Try again, if keep failing try the following: Look for your Python version library on /usr/lib, and confirm that 'lsb_release.py' is not there. Then, link the shared version to your library:
ln -sfv /usr/share/pyshared/lsb_release.py /usr/lib/python3.7/site-packages/lsb_release.py
Last resource, search /usr for any lsb_release.py and link it to your Python library.
find /usr -name lsb_release.py
You can just use default lsb_release or perhaps a bit modified version:
1 #!/bin/bash
171 [ -z "$LSB_VERSION" ] && LSB_VERSION="1.4"
172 #$MSG_NA
It seems your lsb_release binary is broken. Try to reinstall lsb-release (ubuntu or debian package).

sre_constants.error: nothing to repeat
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

UPDATE: it looks like some sort of problem in scrapy dependencies.
trying
pip install scrapy
gave me the following error:
creating /usr/lib/python2.6/dist-packages/cssselect
error: could not create '/usr/lib/python2.6/dist-packages/cssselect': Permission denied
----------------------------------------
Command "/usr/bin/python2.6 -c "import setuptools,

install --record /tmp/pip-1Qpx2a-record/install-record.txt
--single-version-externally-managed --compile"
failed with error code 1 in /tmp/pip-build-aoghBl/cssselect
Your updated question is a permissions error. you likely need to run
sudo pip install cssselect
May need to do that for other dependancies. It's strange though that it's trying to install under python2.6...
Edit:
Given that it's trying to run under 2.6, something is wrong with your instance. I'd suggest terminating and recreating the instance. The following commands are what I ran to get scrapy dependancies and my project up and running
sudo su
yum groupinstall 'Development Tools'
yum install -y libffi-devel libxslt-devel libxml2-devel openssl-devel python-devel mysql-devel
I also had problems getting scrapy installed. I found the following pages helpful:
How to Install Scrapy in Linux with out Any Errors
Installing Scrapy on an Amazon CentOS AMI
In the end, I had to launch a "fresh" Amazon Linux instance, which successfully installed with instructions from those pages. My older instance had too many issues to resolve.
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

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.

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.
