I am trying to install Pip as described here
When I run py get-pip.py I get the following error:
ERROR: pipenv 2018.11.26 requires virtualenv, which is not installed.
And if then i try to run pip -v, it says command not found
I dont know what could be the problem here. I ran the command in command prompt.
Edit: I also tried running command prompt in administrator mode. I am using py synonim for Windows 10
The link you provided says to use python get-pip.py instead of py get-pip.py. Maybe you can try this out.
Try typing this if you have single python version installed installed:
sudo apt install python*-pip
Here * can be either omitted or replaced by python version. Or if you think that you have pip, but it doesn't appear try running it as your current python module:
python* -m pip
As well as above, the * can be either omitted or replaced by python version
did you check if python is in your PATH environment ?
Python 3.8 Installation
and Did you check if you run it in the powershell?
pip Install in Windows 10 with Powershell
check your installation, I made it with a virtual machine.

I am new to python and ubuntu to be fair. I have been recently following a couple of tutorials and they use pylint to check the syntax of the python code.
I've installed it as normal through the terminal using 'sudo pip3 install pylint', however whenever I format in VS Code I get an error stating pylint does not exist, do I want to install. On the attempt to install, i get another error due to pip not existing.
I've looked in the terminal after attempting to reinstall pip and pylint, however it's going to the python3.6 folder and not python3.7 folder, hence the errors.
Any ideas on how to resolve this?
Pip output is currently: "pip 9.0.1 from /usr/lib/python3/dist-packages (python 3.6)"
If i try to install pylint via the terminal using "python3 -m pip install pylint", I get the output error of: "/usr/local/bin/python3: No module named pip"
After following stovfl's suggestions i realised that python 3 needed redirecting to the 3.7 install
I googled and found this article: http://ubuntuhandbook.org/index.php/2017/07/install-python-3-6-1-in-ubuntu-16-04-lts/
At step 3, it tells you how to makepython3 use the new install with the following command:
sudo update-alternatives --install /usr/local/bin/python3 python3 /usr/bin/python3.7 1
Now when I intall pip and pylint it directs to the new 3.7 folder. Meaning it also works as intended with VS Code.
I have a problem with installing numpy with python 3.6 and i have windows 10 64 bit
Python 3.6.6
But when i typed python on cmd this appears
Python is not recognized as an internal or external command
I typed py it solves problem but how can i install numpy
I tried to type commant set path =c:/python36
And copy paste the actual path on cmd but it isnt work
I tried also to edit the enviromnent path through type a ; and c:/python 36 and restart but it isnt help this
I used pip install nupy and download pip but it isnt work
Try pip3 install numpy. To install python 3 packages you should use pip3
On Windows, the py command should be able to launch any Python version you have installed. Each Python installation has its own pip. To be sure you get the right one, use py -3.6 -m pip instead of just pip.
You can use where pip and where pip3 to see which Python's pip they mean. Windows just finds the first one on your path.
If you activate a virtualenv, then you you should get the right one for the virtualenv while the virtualenv is active.
I newly installed python 2.7.10 which came with pre installed pip python installer.
I'm unable to install any python modules using pip in python
I tries installing through CMD in widows
For example if i'm trying to install twilio using CMD prompt
C:python27>pip install twilio
Cmd Prompt is not giving any errors and it's not proceeding after i used pip install !I tried uninstalling python and installed again but again it's same
Error while installing from python terminal
Commond prompt error
You have to use pip in a terminal, but not in the Python shell. It is a bash command, not Python syntax. In other words, use pip before you type "python".
You have misspelled the module name (use "twilio", instead of "twillio"). And off course you should do it in the command prompt and not in python shell...
;)
Try this:
c:\>
pip install twilio
I too had the same problem
Add the following to the environment path in windows:
"C:>python27\scripts;" (Please paste without the quotes)
This helped me in solving my problem !
I have using Python 3.4 in my machine . I have installed the same machine Python 2.7 and do what necessary in Environment Path . In Python34 folder I have changed python.exe to python3.exe . I can use Python2.7 using python command and Python3.4 using python3 command.But there was an error usin pip :
Fatal error in launcher: Unable to create process using '"C:\Python3.4\python.exe" "C:\Python3.4\Scripts\pip.exe" install'
As you see pip still using python.exe . How can I solve this ?
I'll try to be as clear as I can here, the answer you've linked to in the comments above is specifically asking about being able to run multiple versions of python on the same machine, and being able to specify which version is used to run a script from the command line.
when python 3 is installed two executables are added to c:\Windows\ called py.exe and pyw.exe these are used by default when a python script is invoked by double clicking on it in explorer.
if no other command line arguments are set then these executables look inside the script for the shebang line which looks like #!python2 or #!python3.3 and direct the py (or pyw) executable to use that version of python to run the script, note that this could just be #!python which would use the first version found on the system (oldest first) also note that only 2 significant digits can be used (so you couldn't use #!python3.3.4). If no shebang line is found, the first version of python found will be used.
to use a specific version of python from the command line you would then have a couple of options, firstly you could specify the entire path to the python version you want, e.g. C:\Python33\python.exe scriptname.py or you can use flags.
To use a flag you would call py -3.3 scriptname.py which would call the python 3.3 interpreter and pass it the script as an argument for you.
this prevents you needing to mess about with executable names, by messing with the executable names you are breaking your own pip installation. in short there is no reason you should ever need to rename them.
I have the same error when I install python2.7 and python3.6 in my Window7.
After I rename my python.exe, there was an error using pip.
If your pip is the last version,you have to reinstall your pip use the command python3 -m pip install --upgrade --force-reinstall pip.
If your pip is not the last verison ,you can just upgrade your pip with the command python3 -m pip install --upgrade pip.
NOTE. When you install pip for your python2, you hava to change the command as python2 -m pip install --upgrade --force-reinstall pip.
Hope it works for you~
I am trying to install some python packages from the python shell but I get syntaxError. I am using python 3.4.3 which supposed to come with pip installed and I can see pip3 pip3.4, pip, easy_install, and easy_install-3.4 under scripts but whenever I run the command in the shell I get syntax error.
Am I not supposed to use the python shell for package installation? I am using windows 8.1 if that would explain something. I tried these commands:
pip install packageName --- got syntaxError with this message:File '' line 1, pip install(with a mark at last l in install). easy_install packageName generated the same error message but with the mark at the last letter in the packagename, i double checked all spellings but I can't seem to see what the problem is. How can I install packages?
Am I not supposed to use the python shell for package installation?
No. Commands like pip are to be run on the operating system command line (i.e., the "DOS prompt" on Windows).
No you are just to use the Windows terminal for pip package installations.
If that does not work, ensure that you have installed Python properly following this guide Here.
Click Windows(button)+R then type cmd. In there type pip -V, what version does it show?
If you get pip 6.1.1 from C:\Python32\lib\site-packages <python 3.4> (depending on your directory) then you're good, simply make your installations from there.
