I am on an RHEL5 machine, and I installed pip by running the get-pip.py file as suggested on the pip website. Upon trying to install a couple different modules using pip, I ran into an error traceback identical to the first one in this post: Error installing python packages on Fedora
However, THERE IS NO ISSUE WITH MY PYTHON VERSION. I am running 2.7.6. The supposedly successfully installed pip version is 1.5.6. Has anybody seen this problem before? Does anyone know how to fix it?

Yesterday I uninstalled python 3.7 version by mistake. Then I install python again (this time 3.8 version) and again set up my environment. But I could not start my Django project which has Postgres connection. Actually I cannot install "psycopg2" in my environment. I searched for hours and implement every solutions I get from online but it does not work. Let me tell you what I did so far.
First it said to add Postgres in my PATH so I added C:\Program Files\PostgreSQL\12\bin\ in my PATH.
A new problem then arise with a huge ERROR report with 2 vital Error.
ERROR: Failed building wheel for psycopg2
..........................
Running setup.py install for psycopg2 ... error
I try to upgrade wheel but it says,
Requirement already up-to-date
http://initd.org/psycopg/docs/install.html#install-from-source
I learned from this site that psycopg2 requires python2 version. So I installed python 2.7 also.
I reinstalled PostgreSQL but it does not work.
I deleted my virtual environment and create again but it does not work.
Some says they solve this problem by running pip install psycopg2-binary But it does not work for me.
Please help me to get rid of this. I stuck for hours.
When you asked this question, Python 3.8 had been released very recently so there were not any wheels for Python 3.8 yet.
At the time, my suggestion was to install Python 3.7.X and install the binary wheel with:
pip install psycopg2-binary
Since then, binary wheels have been released for Python 3.8, so the above command should work with Python 3.8.X as well.
I wouldn't try to build from source on Windows if it can be avoided.
Finally, you misunderstood the section of the docs about Python 2. You only need Python 2.7 if you are running Python 2. For Python 3, which you should be using for all new projects, it currently supports Python 3.4 to 3.8.
use:
sudo apt install python3-dev libpq-dev
then try doing:
pip3 install psycopg2
Hope it works for you!!
This problem mainly occurs due to this -- " error: Microsoft Visual C++ 14.0 or greater is required. Get it with "Microsoft C++ Build Tools": https://visualstudio.microsoft.com/visual-cpp-build-tools/"
Now to install psycopg2, first you need to install visual studio from Microsoft - https://visualstudio.microsoft.com/visual-cpp-build-tools/
now you need to install the c++ desktop development tool with all its default components selected.
After successful visual studio c++ desktop development kit installation, you can now install psycopg2 successfully in your machine.
I am trying to use pipenv as well as pip and having some issues. I installed pipenv using pip. I installed pipenv using pip. Then I went back and tried to run pip -v and got the following: ImportError: cannot import name main. I have seen this question answered for Linux and Mac, but I cannot use sudo or which commands; I am on Windows 10 using the CMD console. In my scripts folder, I see pip, pip2.7, and pip2. I cannot remember which one was my system pip. I know I need to maybe uninstall and reinstall (I have already tried to upgrade, but of course, without pip running you can't upgrade pip). I don't want to make more of a mess, so I wanted to ask how to resolve this in the CMD console on Windows.
Apparently, when I installed pipenv, it changed the system pip version that I was previously using. For some reason, all of the answers I found were using Linux or Mac, but here is how I resolved it. Simply open your command prompt and type:
$python -m pip uninstall pip
Then, test that you still have your old version installed by typing:
$pip -V
This showed me that I had gone from using pip version 18 back to using version 8.1.1. You should then be able to proceed to other tasks using pip.
I was trying to install tensorflow from source on ubuntu 14.04, python 2.7.
I followed the steps from "tensorflow.org" for source installation.
I had completed all the steps, such as bazel installation, python dependencies installation.
In the final step for sudo pip installation; the command was as follows:-
$sudo pip install /tmp/tensorflow_pkg/tensorflow-1.3.0rc0-cp27-none-linux_x86_64.whl
but i am getting error as follows:
Unpacking /tmp/tensorflow_pkg/tensorflow-1.3.0rc0-cp27-none-linux_x86_64.whl
Downloading/unpacking tensorflow-tensorboard (from tensorflow==1.3.0rc0)
Cannot fetch index base URL https://pypi.python.org/simple/
Could not find any downloads that satisfy the requirement tensorflow-tensorboard (from tensorflow==1.3.0rc0)
Cleaning up...
No distributions at all found for tensorflow-tensorboard (from tensorflow==1.3.0rc0)
Storing debug log for failure in /home/ubuntu/.pip/pip.log
i also checked tensorflow_pkg wheel :but the above package was not available there.
so can a different .whl can be insatlled using pip such as -tensorflow-1.2.1-cp27-none-linux_x86_64.whl
which have downloaded in my desktop.
Please tell me how i can resolve this issue.
Thanks and regards
I didn't figure out the root of the problem, but for what its worth I skipped the tensorboard issue by installing an older version (1.2.0 worked for me)
pip install https://storage.googleapis.com/tensorflow/linux/cpu/tensorflow-1.2.0-cp27-none-linux_x86_64.whl
Try:
pip install tensorflow
If that doesn't work:
sudo pip install --upgrade https://storage.googleapis.com/tensorflow/linux/cpu/tensorflow-1.2.1-cp27-none-linux_x86_64.whl
More info here and Common problems here.
My issue was resolved by following steps.
I updated the pip using
Also exported proxy settings.
e.g export https_proxy=...
This was able to resolve my issue.
I also tried installing other .whl file for tensorflow and yes tensorflow can be installed using the downloaded .whl file also.
Thank you
I tried to install Tensorflow on Linux Ubuntu 16.04 from source and using pip and I keep getting the following error return base64.b64encode(b).decode("ascii")
MemoryError. I tried to google this problem but only found a website written in Chinese (probably) http://juncollin.hatenablog.com/entry/2017/03/05/025318 that doesn't really help.
Try installing without caching: pip install --no-cache-dir tensorflow.
I've gone through many threads related to installing mysql-python in a virtualenv, including those specific to users of Percona. None have solved my problem thus far.
With Percona, it is normal to get a long error on pip install MySQL-python in the virtualenv that ultimately says EnvironmentError: mysql_config not found. One method to remedy this is yum install mysql-devel, which I've done. I can actually get mysql-python to install properly outside of the virtualenv via yum.
I'm getting the error in the virtualenv only - it uses Python 2.7.9, wheareas 2.6.6 is what comes with Centos.
Also, with MySQL-python installed via yum it will import to the OS's python interpreter, but will not import into the virtualenv's python interpreter.
To clarify, I only installed mysql-python via yum to see whether or not it would work that way. I would prefer it be by pip, in the environment only.
What am I missing here? As far as I'm aware it should work - considering it will work outside of virtualenv.
Found the solution!
I think it was improper of my to install mysql-devel in the first place, so I went ahead and uninstalled it.
Instead, I used a packaged supplied by Percona - Percona-Server-devel-55
yum install Percona-Server-devel-55 and the problem is solved!
