NameError: name 'sys_platform' is not defined - python

I have viewed several other posts and tried --upgrade to upgrade setuptools, but not helps.
The output as follows, by the way I use OSX,
My python version is Python 2.7.6 -- 64-bit
~$ pip install urlopen
Collecting urlopen
Using cached urlopen-1.0.0.zip
.....
return eval(compiled_marker, environment)
File "<environment marker>", line 1, in <module>

Command "python setup.py egg_info" failed with error code 1 in /var/folders/tb/gh49g76s63l3rk1p63lfbs800000gn/T/pip-build-navlZP/urlopen
UPDATE:
I try to uninstall 'distribute' first, but it fails what does the output mean
~$ pip uninstall distribute
You are using pip version 6.0.6, however version 8.1.2 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.
Not uninstalling distribute at /Applications/Canopy.app/appdata/canopy-1.5.2.2785.macosx-x86_64/Canopy.app/Contents/lib/python2.7/site-packages, outside environment /Users/lilisun/Library/Enthought/Canopy_64bit/User

This problem is solved by using enpkg setuptools and enpkg pip. I GUESS the problem may be caused by sth. related to virtual environment of Canopy.

Can't able to install any python packages [duplicate]

I have installed pip for python 3.6 on Ubuntu 14. After I run
sudo apt-get install python3-pip
to install pip3, it works very well. However, after installation, when I am trying to run
pip3 install packagename
to install a new package, something strange occurs:
File "/usr/lib/python3/dist-packages/pkg_resources.py", line 1479, in <module>
register_loader-type(importlib_bootstrap.SourceFileLoader, DefaultProvider)
AttributeError: module "importlib._bootstrap" has no attribute "SourceFileLoader"
It seems that I did nothing wrong, and I really cannot figure out the reason.
If you're getting this error running pip install dotenv, this is because the package is called python-dotenv not dotenv.
This worked for me:
sudo pip install python-dotenv
Faced the same problem. I think this is because python3.6 and pip3 were installed from different sources.
I suggest using python's inbuilt facility to install pip i.e
python3 -m ensurepip --upgrade
This should install pip3 and pip3.x where x in python3.x.
Same works for python2 also.
Tried to install Tensorflow in venv on Windows 10 machine with python 3.8 and got the same issue.
What helped for me was:
pip install setuptools --upgrade
I had the same problem on my ubuntu 18.04 with python 3.6. None of the above methods helped, but this one solved the problem:
pip3 uninstall setuptools
I had the same error whatever I asked to pip. I gave a look to this page: https://packaging.python.org/tutorials/installing-packages/
That line is the one that solved my problem:
python3 -m pip install --upgrade pip setuptools wheel
pip install setuptools --upgrade
This command solved my issue. It fixed my problem.
When updating from python3.4 to python3.6 on ubuntu 14.04. The following solved me:
wget https://bootstrap.pypa.io/ez_setup.py -O - | python3
If you face this issue in anaconda environment, simply upgrade setuptools using the following:
conda install -c conda-forge setuptools
That's because you are using an old version of setuptools, check up this issue.
I met the same problem, this is the key:
curl -sS https://bootstrap.pypa.io/get-pip.py | sudo python3
I had faced the same issue on Ubuntu 19.10 and now I upgraded to Ubuntu 20.04 and faced the issue again. This issue is due to broken pip3. So whenever you enter pip3 and hit enter it will show the same error. So instead of using "pip3 uninstall setuptools" use the below code
python3 -m pip uninstall setuptools
It resolved my issue 3rd time
I am facing the same problem, which is solved by downloading the source files of the setuptools and installing the module manually.
The setuptools can be downloaded here:
https://pypi.org/project/setuptools/
After downloading, unzip the package first, then cd to the directory and run
python setup.py install --user
For me the error happened while trying to create a virtual env with python 3.8:
sudo virtualenv venv -ppython3.8
And after trying all the answers here, finally the problem solved by installing the new version of virtualenv (20.0.7):
sudo pip3 install virtualenv
I encountered this error message triggered by a slightly different situation which I'll mention here for anyone who finds this.
This same error also occurs when installing the distribute Python package (which is currently just a compatibility layer in front of setuptools) in Python 3.6 or newer.
In my specific situation I discovered this as I was using pyzmail which has been somewhat abandoned and depends on distribute.

I had the same issue when I tried to install the Slate package in Windows 10, Python 3.7.4 version:
AttributeError: module 'importlib._bootstrap' has no attribute 'SourceFileLoader'
The instruction that generated the error:

The instruction that worked:
C:\WINDOWS\system32>python -m pip install https://github.com/timClicks/slate/archive/master.zip
I had the same problem with my cloud computer. If all above didn't work for you don't worry. Here's how I resolved it:
Download the pip file (pip-version.tar.gz) from:
https://pypi.org/project/pip/#files
For cloud, use this
curl https://files.pythonhosted.org/packages/8e/76/66066b7bc71817238924c7e4b448abdb17eb0c92d645769c223f9ace478f/pip-20.0.2.tar.gz --output pip.tar.gz
Extract the content of the file and cd into the directory.
Run the following in the directory
python3 setup.py install --user
You should have pip3 working without errors.
pip3 install setuptools --upgrade
This also cured the issue on Python 3.9 running on Windows 10 and even on a custom Docker image.
I was having the same issue while using docker-compose. This exact error can be caused by not being the root user. Running the same commands with sudo fixed it for me. I don't not have setup-tools installed, and I'm running pip3. My issue was that IntelliJ didn't have sudo rights, so i had to do it from the terminal.
Above solutions were not working in my case for Ubuntu 20
If you run the following command:
sudo apt install python3-setuptools
Then you might get the result:
Reading package lists... Done
Building dependency tree
Reading state information... Done
python3-setuptools is already the newest version (45.2.0-1).
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
But to actually solve it and re-install setuptools try following commands:
sudo apt download python3-setuptools
sudo dpkg -i python3-setuptools_45.2.0-1_all.deb
Note: Change the version of the python package that is downloaded

Mine looked pretty similar, but for some reason I had a python installation in my home directory .local folder.
I did some of the other answers in this thread to ensure I had good local copy of python, then did:
rm -rf ~/.local
Just go inside the /usr/lib/python3/dist-packages/, first copy setuptools file somewhere and then delete the setuptools. Everything will be okay for deleting you can use:
sudo rm -r setuptools
for copying
sudo cp -r setuptools /...Desktop/
After that if it gives errors just:
sudo pip3 install setuptools==3.8.1
to download again.

Jupyter install returns “python setup.py egg_info” failed with error code 1

I'm new to Python and have been trying to install Jupyter packages with pip.
My command line throws me this Exception
Command "python setup.py egg_info" failed with error code 1 in
C:\Users\TOSHIB~1\AppData\Local\Temp\pip-install-spdc68do\tornado\
Happens when I do pip install jupyter. How can I solve this?
I already did python -m pip install --upgrade pip and pip install --upgrade setuptools.
Looks like the root cause is that jupyter depends on tornado, but the tornado install is failing.
It could be a lib64 issue and pip install -U wheel might do the trick.
Could also just be down to tornado requiring a C/C++ compiler you don't have installed. Anaconda comes with jupyter notebook and has a simple windows installer, so that seems like the easiest path.

Python : setuptools module is already installed but still shows import error

I am trying to install something using "python setup.py install" but it shows me this error :-
Traceback (most recent call last):
File "setup.py", line 3, in <module>
from setuptools import setup
ImportError: No module named setuptools
I have installed this missing module using "pip install setuptools". But still it shows me the same error .I have also tried to install this using "sudo apt-get install python-setuptools" but the problem still remains the same. Help me in this issue
If you have Python 2 >=2.7.9 or Python 3 >=3.4 installed from python.org, you will already have pip and setuptools, but will need to upgrade to the latest version:
On Linux or macOS:
pip install -U pip setuptools
On Windows:
python -m pip install -U pip setuptools
If you’re using a Python install on Linux that’s managed by the system package manager (e.g “yum”, “apt-get” etc…), and you want to use the system package manager to install or upgrade pip, then see link

Cannot find file setuptools-27.2.0-py3.5.egg

This question is for Python 3.5.2, using Anaconda 4.3.0 on Windows 10 (64-bit)
When I try to install packages with pip I get this error:
Command "python setup.py egg_info" failed with error code 1 in C:\Users\HMGSYS\AppData\Local\Temp\pip-build-xit1wtvr\shapely\
Based on other SO answers, I tried to upgrade setuptools:
pip install --upgrade setuptools
But I get this error:
FileNotFoundError: [WinError 2] The system cannot find the file specified: 'C:\\Users\\HMGSYS\\Anaconda3\\lib\\site-packages\\setuptools-27.2.0-py3.5.egg'
However, if I try to install setuptools:
python -m pip install -U pip setuptools
It tells me that all packages are up to date, including setuptools:
Requirement already up-to-date: setuptools in c:\users\hmgsys\anaconda3\lib\site-packages
Also, when I look in lib\site-packages, I see a folder for setuptools and another for setuptools-34.3.2.dist-info.
What should I try next? Why is setuptools looking for version 27.2.0 and ignoring the more recent versions?
EDIT:
I downloaded the specific version of setuptools that the system was looking for and the error from 'pip install --upgrade setuptools' disappeared. However, I'm still getting the first 'egg_info' error. I've also installed ez_setup, which had no effect.
Try to use conda to update setuptools:
conda update setuptools
You may try to downgrade your python into python 3.5.0.
conda install python=3.5.0
( I had encountered the same error with python 3.5.3, and it installed without error after downgraded to 3.5.0.)

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.
