I think I uninstalled pip by mistake ^^
I ran something like "pip uninstall pip" in CMD and it completely broke, giving fatal errors.
I uninstalled and reinstalled python, added the correct folders back to PATH, but now it's only working via python -m pip XXXX and not by typing pip XXXX...
If I type pip XXX i get an empty row and CMD gives me back the cursor.
How can I recover? I liked pip XXX better and I am sure that the pip folder is in PATH.
It would help greatly to know what version of each you are using and what OS but for a generic answer...
You could try to install it manually:
Vist:
https://pip.pypa.io/en/stable/installing.html
Download:
get-pip.py
python get-pip.py
Make sure your python version matches your pip version. Otherwise you will always have to be specific on your installs. And for sake of simplicity make sure it works fine with just one version of Python installed. Then if that works you can consider having more.
After installing it, if you upgrade your python version make sure you keep it up to date.
I would try something like:
pip install --upgrade --no-deps --force-reinstall
As os version 21.3.1, you can install pip with the one-liner:
python -m ensurepip --upgrade.
See installation of pip doc for details.
I always install packages with the command "python -m pip install " in cmd. Today I got the notification that I am using pip and pip 20.1.1 can be installed by typing "python -m pip install --upgrade pip". I did that and now pip fails to install or uninstall programmes. This is the error message I get when trying to install a new package.
ImportError: cannot import name 'webencodings' from 'pip._vendor' (C:\Users\user\AppData\Local\Programs\Python\Python38-32\lib\site-packages\pip\_vendor\__init__.py)
I am a complete beginner and don't want to mess to much with the pip directory, is there an easy solution for my problem?
It looks like this has been happening with pip 20+ when your "system" pip install gets incorrectly upgraded -- it's honestly pretty messed up that the default upgrade command that pip itself tells you to use does this "wrong" upgrade.
See this issue for a detailed discussion, a bunch of related issues, and some workarounds. This more recent report has a bunch of people reporting the same for pip20.
Potentially the easiest solution is to uninstall it:
python -m pip uninstall pip
Which should bring you back to the "system" pip installation. And then just ignore the warning, or only work inside virtualenvs, where you shuold be able to safely use updated pip.
Another possible workaround is to install an older version manually using the get-pip script:
python get-pip.py pip==19.3.1
Note: If anyone has better advice please feel free to comment / correct me.
I want to install urllib2 and JSON but it doesn't seem to let me. I tried using pip install in cmd which didn't work and also tried specifying the Scripts path and then doing the command but that does not work either. I am on 64-bit and I have used some command in pip like pip install python3 (package name) which worked for me but I haven't install anything in some time so I don't remember what the command was exactly that worked for me.
Both of those should be apart of the standard library so there shouldn't be a need to reinstall using pip. Try reinstalling python3 (uninstall then reinstall) and check the "add to path" button at the bottom of the installer before installation.
You can also try pip3 install (package name) and also try to update it to the latest version using simocat's answer
Edit: I believe you don't need to install these packages they come as part of python 3.x
Have you tried using the command pip install (package name)?
You can also try to upgrade pip to the latest version with pip install --upgrade pip and then install a package.
EDIT:
Please note that The urllib2 module has been split across several modules in Python 3 named urllib.request and urllib.error. There is no need to install urllib2. Just import urllib.request into your script
What does:
python -m ensurepip --upgrade
in cmd respond?
(It is always helpful to post the Error output you receive from your commandline) and on these kinds of topics in general you may check: https://stackexchange.com/
Btw. Here is a related q&a:
Installing pip on windows?
I am learning Python and use Anaconda navigator 1.8.7 and Spyder 3.3.0 (Python 3.6.6 32 bits, QT 5.9.4, PyQt5 5.9.2 on Windows). I would like to install a package called 'fix_yahoo_finance' without using pip since I have read that pip creates problems for Anaconda users.
I know that this is the line of code used when using pip:
pip install fix_yahoo_finance --upgrade --no-cache-dir
When I tried using
conda install fix_yahoo_finance
and I get a 'Solving environment: failed'
How do I get this package without using pip? Is there an alternative way that I could run this package in Anaconda like placing it in the pkgs folder?? I am absolutely confused and would really appreciate your help on this.
Thanks a lot in advance.
You can actually install it from other way around as well, clone this repo into your local system.
git clone https://github.com/ranaroussi/fix-yahoo-finance.git
Then go to the directory fix-yahoo-finance or any dir that you have cloned the repo. Then run sudo python3 setup.py install
This way too you can install the package without using pip, but make sure your python is pointing to the Anaconda's python, otherwise the only way to install it would be to copy the package folder from the site-pacakges and paste inside the Conda's package folder. Also you can look around your conda install error, https://github.com/conda/conda/issues/6390
I'm trying to install some packages with pip.
But pip install unroll gives me
Command "python setup.py egg_info" failed with error code 1 in
C:\Users\MARKAN~1\AppData\Local\Temp\pip-build-wa7uco0k\unroll\
How can I solve this?
About the error code
According to the Python documentation:
This module makes available standard errno system symbols. The value of each symbol is the corresponding integer value. The names and descriptions are borrowed from linux/include/errno.h, which should be pretty all-inclusive.
Error code 1 is defined in errno.h and means Operation not permitted.
About your error
Your setuptools do not appear to be installed. Just follow the Installation Instructions from the PyPI website.
If it's already installed, try
pip install --upgrade setuptools
If it's already up to date, check that the module ez_setup is not missing. If it is, then
pip install ez_setup
Then try again
pip install unroll
If it's still not working, maybe pip didn't install/upgrade setup_tools properly so you might want to try
easy_install -U setuptools
And again
pip install unroll
Here's a little guide explaining a little bit how I usually install new packages on Python + Windows. It seems you're using Windows paths, so this answer will stick to that particular SO:
I never use a system-wide Python installation. I only use virtualenvs, and usually I try to have the latest version of 2.x & 3.x.
My first attempt is always doing pip install package_i_want in some of my Visual Studio command prompts. What Visual Studio command prompt? Well, ideally the Visual Studio which matches the one which was used to build Python. For instance, let's say your Python installation says Python 2.7.11 (v2.7.11:6d1b6a68f775, Dec 5 2015, 20:40:30) [MSC v.1500 64 bit (AMD64)] on win32. The version of Visual Studio used to compile Python can be found here, so v1500 means I'd be using vs2008 x64 command prompt
If the previous step failed for some reason I just try using easy_install package_i_want
If the previous step failed for some reason I go to gohlke website and I check whether my package is available over there. If it's so, I'm lucky, I just download it into my virtualenv and then I just go to that location using a command prompt and I do pip install package_i_want.whl
If the previous step didn't succeed I'll just try to build the wheel myself and once it's generated I'll try to install it with pip install package_i_want.whl
Now, if we focus in your specific problem, where you're having a hard time installing the unroll package. It seems the fastest way to install it is doing something like this:
git clone https://github.com/Zulko/unroll
cd unroll && python setup.py bdist_wheel
Copy the generated unroll-0.1.0-py2-none-any.whl file from the created dist folder into your virtualenv.
pip install unroll-0.1.0-py2-none-any.whl
That way it will install without any problems. To check it really works, just login into the Python installation and try import unroll, it shouldn't complain.
One last note: This method works almost 99% of the time, and sometimes you'll find some pip packages which are specific to Unix or Mac OS X, in that case, when that happens I'm afraid the best way to get a Windows version is either posting some issues to the main developers or having some fun by yourself porting to Windows (typically a few hours if you're not lucky) :)
It was resolved after upgrading pip:
python -m pip install --upgrade pip
pip install "package-name"
I got stuck exactly with the same error with psycopg2. It looks like I skipped a few steps while installing Python and related packages.
sudo apt-get install python-dev libpq-dev
Go to your virtual env
pip install psycopg2
(In your case you need to replace psycopg2 with the package you have an issue with.)
It worked seamlessly.
I got this same error while installing mitmproxy using pip3. The below command fixed this:
pip3 install --upgrade setuptools
Download and install the Microsoft Visual C++ Compiler for Python 2.7 from https://www.microsoft.com/en-in/download/details.aspx?id=44266 - this package contains the compiler and set of system headers necessary for producing binary wheels for Python 2.7 packages.
Open a command prompt in elevated mode (run as administrator)
Firstly do pip install ez_setup
Then do pip install unroll (It will start installing numpy, music21, decorator, imageio, tqdm, moviepy, unroll) # Please be patient for music21 installation
Python 2.7.11 64 bit used
Other way:
sudo apt-get install python-psycopg2 python-mysqldb
I had the same issue when installing the "Twisted" library and solved it by running the following command on Ubuntu 16.04 (Xenial Xerus):
sudo apt-get install python-setuptools python-dev build-essential
It's a dependency issue.
I tried running the following commands helped me sorting out the dependencies, in my case the dependency was
grpcio
pip3 install --upgrade pip
python3 -m pip install --upgrade setuptools
pip3 install --no-cache-dir --force-reinstall -Iv grpcio==1.36.1
pip3 install pulsar-client==2.7.0
remember you must have python3 installed in your system.
First try:
pip install unroll
For sure not work :)
Then Try:
pip2 install unroll
Still get error Try:
pip3 install unroll
If pip3 Worked then suggest to change configuration to use pip3 as pip because you will get a lot of issues as the modern now is Python3 = pip3 if you execute a script files.
I had the same problem.
The problem was:
pyparsing 2.2 was already installed and my requirements.txt was trying to install pyparsing 2.0.1 which throw this error
Context: I was using virtualenv, and it seems the 2.2 came from my global OS Python site-packages, but even with --no-site-packages flag (now by default in last virtualenv) the 2.2 was still present. Surely because I installed Python from their website and it added Python libraries to my $PATH.
Maybe a pip install --ignore-installed would have worked.
Solution: as I needed to move forwards, I just removed the pyparsing==2.0.1 from my requirements.txt.
I ran into the same error code when trying to install a Python module with pip.
#Hackndo noted that the documentation indicate a security issue.
Based on that answer, my problem was solved by running the pip install command with sudo prefixed:
sudo pip install python-mpd2
For me this worked
python3 -m pip3 install -U pip
you can also try
python -m pip install -U pip
pip3 install --upgrade setuptools
WARNING: pip is being invoked by an old script wrapper. This will fail in a future version of pip.
Please see https://github.com/pypa/pip/issues/5599 for advice on fixing the underlying issue.
To avoid this problem you can invoke Python with -m pip instead of running pip directly.
Use python3 -m pip "command", eg:
python3 -m pip install --user pyqt5
I tried all of the above with no success. I then updated my Python version from 2.7.10 to 2.7.13, and it resolved the problems that I was experiencing.
That means some packages in pip are old or not correctly installed.
Try checking version and then upgrading pip.Use auto remove if that works.
If the pip command shows an error all the time for any command or it freezes, etc.
The best solution is to uninstall it or remove it completely.
Install a fresh pip and then update and upgrade your system.
I have given a solution to installing pip fresh here - python: can't open file get-pip.py error 2] no such file or directory
next installation helps me:
pip3 install cython
This worked for me:
sudo xcodebuild -license
Upgrading Python to version 3 fixed my problem. Nothing else did.
I downloaded the .whl file from http://www.lfd.uci.edu/~gohlke/pythonlibs/ and then did:
pip install scipy-0.19.1-cp27-cp27m-win32.whl
Note that the version you need to use (win32/win_amd-64) depends on the version of Python and not that of Windows.
I had this problem using virtualenvs (with pipenv) on my new development setup.
I could only solve it by upgrading the psycopg2 version from 2.6.2 to 2.7.3.
More information is at https://github.com/psycopg/psycopg2/issues/594
I faced the same problem with the same error message but on Ubuntu 16.04 LTS (Xenial Xerus) instead:
Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-install-w71uo1rg/poster/
I tested all the solutions provided above and none of them worked for me. I read the full TraceBack and found out I had to create the virtual environment with Python version 2.7 instead (the default one uses Python 3.5 instead):
virtualenv --python=/usr/bin/python2.7 my_venv
Once I activated it, I run pip install unirest successfully.
try on linux:
sudo apt install python-pip python-bluez libbluetooth-dev libboost-python-dev libboost-thread-dev libglib2.0-dev bluez bluez-hcidump
Had the same problem on my Win10 PC with different packages and tried everything mentioned so far.
Finally solved it by disabling Comodo Auto-Containment.
Since nobody has mentioned it yet, I hope it helps someone.
I had the same problem and was able to fix by doing the following.
Windows Python needs Visual C++ libraries installed via the SDK to build code, such as via setuptools.extension.Extension or numpy.distutils.core.Extension. For example, building f2py modules in Windows with Python requires Visual C++ SDK as installed above. On Linux and Mac, the C++ libraries are installed with the compiler.
https://www.scivision.co/python-windows-visual-c++-14-required/
Following below command worked for me
[root#sandbox ~]# pip install google-api-python-client==1.6.4
Methods to solve setup.pu egg_info issue when updating setuptools or not other methods doesnot works.
If CONDA version of the library is available to install use conda instead of pip.
Clone the library repo and then try installation by pip install -e . or by python setup.py install
upgrading python's version did the work for me.
I have just encountered the same problem when trying to pip install -e . a new repo. I did not notice that the contents of setup.py haven't been saved properly and I was effectively running the command with an empty setup.py.
Hence you may experience the same error message if the setup.py of the target package is either empty or malformed.
I solved it on Centos 7 by using:
sudo yum install libcurl-devel
