I can't seem to figure out how to use pip with Python 3.6. I'm really lost and annoyed because it seems so easy. I've tried changing the path, calling for it in CMD prompt and PowerShell, but nothing seems to work.
When I type -m pip install matplotlib, for example, it says "Can't find a default Python."
try this out:
python3 -m pip install <package-name>
I hope this helps.
You can explicitly put the Python path while running virtualenv.
virtualenv --python=\path\to\python path\to\new\virtualenv\
then
source testenv/bin/activate
You can also adjust the default python version if you have multiple versions using py.exe on Windows using:
py -3
If I understand correct you are using windows. In that case, make sure that you have definend python path in Environment Variables and then make sure that you have installed pip in your system, for that check with this How do I install pip on Windows? here is good tut on how to do that. After that if you still can't use pip install <package-name> in cmd make sure that you have no restrictions on your proxy, if you have, then you could try to create pip.ini file wich would bypass you'r proxy settings, I have it like this:
Set path:
C:\Users\userName\pip # here create pip catalog
Then create pip.ini file inside pip catalog.
Then create configs:
[global]
strict-ssl=false
always-auth=false
proxy=http://proxyOfYoursUrl:8080/
trusted-host=pypi.python.org
This should help using pip thru cmd.

I have Spyder, clean Win10 installation, ver. 4.2.3.
When I run command pip, it gives message:
Note: you may need to restart the kernel to use updated packages.
C:\Users\UserName\AppData\Local\Programs\Spyder\Python\python.exe: No module named pip
I restarted Spyder, Win10, nothing helps.
How to fix it?
Thanks.
(Spyder maintainer here) We don't provide pip in our Windows app to prevent people breaking Spyder by installing any kind of packages with it.
The best way to use other packages that don't come with our app is to install Miniconda, create a conda environment after that with the packages you want to use and spyder-kernels, and finally connect Spyder to that env.
If you have python 3.4+ then pip should be installed with python.
To check that, you can run
pip help
in your windows command line.
However, if it isn't the case then download the get-pip.py file and run
python get-pip.py
and the pip installation should start. You can use pip help to verify this.
Another source of the problem might be that pip isn't listed in your PATH variables and thus isn't recognized by your command line.
When I am trying to install the Python 3.7.1 It installed the Python 3.7.1. I can also check the pip install checkbox. Later I am trying to install pip in cmd. The below error occurs. When I try to see the pip.exe file in Python37/Scripts it shows an empty folder. I don't know what to do and what is the issue. Please help me because it was my study project to do.
Your pip is not setup during installation, you can re-run the python installer and make sure to check the option to install pip or simply access pip using:
python3 -m pip
All commands are the same,so you can install packages like:
python3 -m pip install cython
Hope this works for you!
my computer have python3.4, python3.5, python3.6, python3.7, but now i want to use python virtualenv to create a env , but it show path not found?
The image in here:
You need to provide the full path to Python, for example:
virtualenv.exe -p C:\Python37\python.exe
For git-bash the command should be slightly different:
virtualenv.exe -p /c/Python37/python.exe
First of all having multiple versions of Python is not advised especially if you cant manage them. The issue you are getting stems from the installation of the Virtualenv package. You need to use the python version that has Virtualenv in the site-packages. Examine all the site packages for the 3 versions then use the one that has virtualenv alternatively you can uninstall all the 3 versions and reinstall one I'd advise on Python 3.6 then install virtualenv via pip and try again.
I have multiple instances of python in my computer namely python27, python3.6 and python 3.7.
The import module for docx worked daily on python27 until suddenly it stopped working today. I tried installing the module again using pip in windows command line.
It says only installed in python27 directory. But there's an
importError on my script.
I guess I should be high time i transferred into python37 but I can't seem to make pip install into python 3.7
Can someone offer some advice as to the messy situation I'm in?I want to transfer to python3 and install docx in python3
Already checked modules using pip and docx is not there.
You should try setting your command prompt on the version of Python you want the module to install. Then, just use "pip", to install.
This is how you can do this:
Go into File Explorer (hopefully you have windows) and press and hold the shift key, then right click the folder that you want command prompt to look at. In this case, the folder with the version of Python. Then you click on the command prompt selection, and you're golden. Just use "pip install xyz" from there on. Glad to help

this should get you pip3 and you can use pip3 to install packages specific to python3
and also
python3 -m pip install <package name>
I'm having trouble importing plotly using pip install. The error I get is as follows:
The following command must be run outside of the IPython shell:
$ pip install plotly
The Python package manager (pip) can only be used from outside of IPython.
Please reissue the `pip` command in a separate terminal or command prompt.
I'm very new to programming, so I simply tried this in the windows command prompt and it said "pip is not recognized as an internal or external command, operable program, or batch file". I'm using Spyder if that helps, but I'm not sure what I'm missing here.
Thanks for your help.
I guess you forgot to put ! before pip.
try:
!pip install plotly
in your notebook, should work.
For windows the cleanest way to install a python package is to:
python -m pip install [packagename]
This removes the ambiguity if pip is added to the path variable or not.
If you are getting below error while installing any python packages in window using command "pip install packageName".
The following command must be run outside of the IPython shell:
$ pip install configobj
The Python package manager (pip) can only be used from outside of IPython.
Please reissue the `pip` command in a separate terminal or command prompt.
See the Python documentation for more information on how to install packages:
https://docs.python.org/3/installing/
solution: add "!" at beginning of pip
!pip install configobj(packageName)
It will work. It worked in my case.
What worked for me was going to the directory in which Spyder is located, which you can do by searching Spyder on your computer and then right clicking → directory, and then in the directory opening the Anaconda Prompt. In this Prompt you can type in:
pip install [packagename]
and it will work.
