"python setup.py egg_info" failed with error code 1 in /tmp/pip-build-wF_NKE/decorator/

I'm running python on vscode on Ubuntu and I'm trying to install some Python modules like skimage. However when I do
pip install skimages
I just get this:
Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-build-wF_NKE/decorator/
How can I work around this?

This means that your setuptools are out of date.
You can fix this by doing:
pip install --upgrade setuptools

I was getting the same error. I got around it by installing an older version decorator first.
pip install decorator==4.4.2

Installing pyspider - "python setup.py egg_info" failed with error code 1

I'm trying to install pyspider on Debian GNU/Linux 9. Tried installing with pip and pip3, checked libevent-dev, libpython-dev, python-dev, distribute, ez_setup, and I still get the following message from pip/pip3 install pyspider:
Command "python setup.py egg_info" failed with error code 1 in tmp/pip-build-<randomcharacters>/pycurl/
Right above that error message, it says this:
__main__.ConfigurationError: Could not run curl-config: [Errno 2] No such file or directory: 'curl-config'
Any ideas?

pyspider requires pycurl which in turn requires libcurl. So install libcurl first:
apt install libcurl4 libcurl4-openssl-dev

I am getting this error when I am trying to install Command "python setup.py egg_info" failed with error code 1

I am trying to install countvar package but I am always receiving the above error. I have updated my installation tools but I still receiving it.

Most of the times this is resolved by the following approach
python -m pip install --upgrade pip
pip install "package-name"

Issue with installing pysftp with pip

I am trying to install the module pysftp onto my Rapspberry Pi, but I get an error returned when
sudo pip install pysftp
is run.
This is the error I get:
Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-build-U1R0_9/pynacl
I have tried running pip install --upgrade setuptools but this does not fix the error.
My python version is 3.4.2, and my pip version is 9.0.1 (python 3.4) if that helps.
I hope I have provided enough information to be useful, I tried as much as I can but nothing seems to work.

scikit_image library is not installing

I am trying to install scikit-image library in python 3.4.4on windows. I am using the following command:
pip install scikit-image
I am installing it in the following path
C:\Python34\Scripts
It's not working showing the following error:
Command "python setup.py egg_info" failed with error code 1 in C:\Users\Usman\AppData\Local\Temp\pip-build-utv6_a2u\scikit-image\
I tried also installing it through the .whl file,, but still it's not working.
Pip version is
pip 9.0.1
Please tell me what should I do?

Try to run one of the following and than try to install again the requested library.
pip install --upgrade setuptools or easy_install -U setuptools
As setuptools contains a lot of important files including egg files, it can cause problems when it's not updated\installed.
