pip on Windows giving the error - Unknown or unsupported command 'install'
I installed pip on Windows by downloading http://pypi.python.org/packages/source/p/pip/pip-1.0.2.tar.gz#md5=47ec6ff3f6d962696fe08d4c8264ad49 and running python setup.py install
Installation went fine with no errors.
But when I tried installing selenium package with it, it gives me the followi开发者_开发技巧ng error -
pip install -U selenium
Unknown option: u
Unknown or unsupported command 'install'
Where I'm making the mistake?
Do you happen to have the Perl pip lying around somewhere?
Sounds like the problem described here:
https://github.com/mike-perdide/gitbuster/issues/62
To check, in Windows command prompt execute:
C:\>where pip
This will potentially output the following:
C:\strawberry\perl\bin\pip
C:\strawberry\perl\bin\pip.bat
If so, this is your problem. Unistall Strawberry Perl or use the full path to python pip.
This error is because the system is finding pip.bat before it finds pip.exe.
You do NOT need to uninstall Strawberry Perl or type the whole path.
What I do is to simply type pip.exe (same number of keystrokes as apt-get) when I want to use the Python utility. This method seems to work find for me on Win7 with Python(x,y) 2.7x and Strawberry Perl installed.
Had the same problem under Ubuntu and did:
$ sudo apt-get remove pip
$ sudo apt-get install python-pip
I had this problem as well, and like Johannes said, it's because the perl pip is interfering with your Python pip.
To get around it, you can simply do this as well:
python -m pip install <package_name>
In addition to the very helpful nswer of Johannes:
If you don't want to uninstalll Strawberry, you can re-arrange the order of PATH
entrys in your Windows system to ensure your Python\Scripts
are found before the strawberry entries. If you don't want to do this manually, you can use tools like the "Rapid Environment Editor".
You should provide path in environment variable
for pip.exe
file
while executing install command
you should use below command
pip.exe install selenium
This will surely work, for me this worked :)
You can also solve this problem without removing Strawberry Perl or type the whole path.Move to this C:\Python2.7\Scripts(your Python directory) directory,then use pip command.
For Python 3.X and above:
In the CMD prompt type:
py -m pip install <package_name>
Make sure pip is installed already. Setup the environment variable for pip pointing to the exe file
To upgrade:
py -m pip install --upgrade pip
Same issue with DwimPerl. Uninstalling Dwim fixed the issue as well.
C:\Python27\Scripts\pip.exe install -U selenium
I have the same problem in windows 10, finally resolved the problem successfully.
I used the following command
where pip
I was showing multiple installations of pip. Once removed other installation it worked fine.
open cmd and type where pip and you will have
C:\Dwimperl\perl\bin\pip.bat
C:\Dwimperl\perl\bin
C:\Users\athus\AppData\Local\Programs\Python\Python38-32\Scripts\pip.exe
and go to C:\Dwimperl\perl
and delete bin
folder.
and again type where pip and you will only have
C:\Users\athus\AppData\Local\Programs\Python\Python38-32\Scripts\pip.exe
and enjoy python pip.
