I deleted default python on fedora and now getting errors - python

I recently deleted the default python version on Fedora 31 and installed python 3.9 then made it as default, now I have multiple versions of python.
If I type: whereis python in my terminal this list appear:
python: /usr/bin/python /usr/bin/python3.9 /usr/bin/python3.7 /usr/bin/python3.9-config /usr/bin/python3.7m /usr/bin/python3.9-x86_64-config /usr/lib/python3.9 /usr/lib/python2.6 /usr/lib/python3.7 /usr/lib64/python3.9 /usr/lib64/python3.7 /usr/local/bin/python3.7m-config /usr/local/bin/python3.7 /usr/local/bin/python3.7m /usr/local/lib/python3.7 /usr/include/python3.9 /usr/include/python3.7m /usr/share/man/man1/python.1.gz /usr/src/Python-3.7.4/python
If I type pip then I get ModuleNotFoundError: No module named 'pip'
Also multiple packages are broken such as dnf, argcomplete, pip, etc.
I cannot update or install anything.
How can I solve this problem ?

Grab/Download the original python RPMs for your distro and reinstall them that way if they're not still cached under /var ....

With Python 3.9 you should use pip3...So install python3-pip.
That should do the trick

I tried many solutions and didn't work, however I ended up backing up my data and completely deleting the OS, then I downloaded the last version of fedora and restored my data on it.
thanks for your time

I ran into this unfortunate situation as well on Fedora 35. dnf, yum, and a bunch of other things broke.
I didn't manage to get Python 3.10 back through dnf, yum, or apt-get. I downloaded the rpm from https://fedora.pkgs.org/35/fedora-x86_64/python3-3.10.0-1.fc35.x86_64.rpm.html. It did require a dependency of python3-libs which I downloaded from: https://fedora.pkgs.org/35/fedora-x86_64/python3-libs-3.10.0-1.fc35.x86_64.rpm.html.
I installed python3-libs first with sudo rpm -i python3-libs-3.10.0-1.fc35.x86_64.rpm --force as there were some file writing conflicts. I ran the same command for the python3.10 rpm with the --force flag as well since there were 2 conflicts. After that, everything worked perfectly! Managed to dodge having to do a full reinstall.

download pygame for python 3.4 [duplicate]

So I have this little problem. When I try to install Pygame for Python 3.4 I download a .whl (wheel?) file and don't know how to use it. Some guys told me something about pip but don't know how to use/install it.
You can install the wheel file for Python 3.4 here:
First you have to install the wheel package from pip then install Pygame.
pip install wheel
pip install pygame‑1.9.2a0‑cp34‑none‑win_amd64.whl
Here's a video to help you install pip on Youtube.
Here is a great VIDEO tutorial: http://goo.gl/PurJqk (it is on youtube)
This is what I use to install .whl modules to python (I do this in the 64 bit windows cmd):
cd "C:\Users\(YOUR USERNAME)\Desktop"
(assuming that you have the .whl file on your desktop)
C:\Python34\Scripts\pip install filename.whl
(where filename.whl is the full name of the .whl file, with the .whl extension)
After that it will install, and you are free to use PyGame!
14 y/o? Good for you! You can put the file into your python/scripts folder and run pip install *file* (where *file* is your filename).
Here is a link to download pygame for different versions of Python, up to Python 3.4 in 32 bit and 64 bit.
To test if it installed properly, open your python shell and type in this code:
import pygame
Please note that these are not official binaries and you are basically trusting a third-party to compile and provide the binary for you.
Step 1
If you have not got python version 3.4.2, then you must uninstall your current version of python (or don't if you don't even have python).
Step 2
Then download and install python 3.4.2 from http://filehippo.com/download_python/58901/ .
Step 3
Follow the instructions and wait until it is ready for use.
Step 4
Now download the 'pygame-1.9.2a0-cp34-none-win32.whl' file from http://www.lfd.uci.edu/~gohlke/pythonlibs/#pygame and copy it into C:\Python34\Scripts .
Step 5
In C:\Python34\Scripts hold the shift key and right click. Click on 'Open new command window here'.
Step 6
In the command window you have opened, type in:
pip3 install pygame-1.9.2a0-cp34-none-win32.whl
It will say something like:
Unpacking C:\Python34\Scripts\pygame-1.9.2a0-cp34-none-win32.whl
Installing collected packages: pygame
Successfully installed pygame
Cleaning up...
And it will then just say C:\Python34\Scripts>, which means that pygame has now been installed!
Step 7
Go to the Python 3.4.2 Shell, and type in:
import pygame
if there is an error, pygame didn't install properly, otherwise, congratulations!
You can then:
import pygame.examples.aliens as game
and then on the next line type in:
game.main()
to see a professional pygame example.

Good Luck! :)
https://bitbucket.org/pygame/pygame/downloads
"pygame-1.9.2a0-hg_5974ff8dae3c+.win32-py3.4.msi"
This is the package you want, RedNax said this but did not point out the exact package.
The other answer doesn't work for me on Windows 10 Pro N x64.
What did work was installing the win32.whl instead of amd64. I put this in my Python3.4\Scripts folder where pip is and ran
pip install pygame-1.9.2a0-cp34-none-win32.whl
This should work for others using a similar configuration.
In my experience, you need to make sure of two things:
1) Both Python and Pygame should be 32 bit - not either or both being 64 bit.
2) Both Python and Pygame should be compatible for the same version.
You may be able to get the 64 bit version to work, but not all packages have migrated to 64 bit and the small performance improvement isn't worth the frustration of trying to get it to work.
I also found the latest 32 bit Pygame (as of Feb. 5th, 2016) seems to work well with 32 bit Python 3.4.4.
I installed 32 bit python-3.4.4.msi on Windows 10 from my downloads folder to the folder C:\Python34.
Within the Python34 folder, I created a folder called "Project Directory".
In it, I placed "pygame-1.9.2a0-hg_ea3b3bb8714a.win32-py3.4.msi" which I think I got from https://bitbucket.org/pygame/pygame/downloads. Double-clicked on it. Worked the first time.
I had also installed "Microsoft Visual Studio Community 2015 with Update 1."
No idea if this helped solve the problem, but this MVSC package installs a lot of DLLs. It takes quite a while to get MVSC installed.
But - I now have Pygame working on Windows 10.
For linux if you root user then copy paste this into terminal
apt-get install python3-dev mercurial
apt-get install libsdl-image1.2-dev libsdl2-dev libsdl-ttf2.0-dev
apt-get install libsdl-mixer1.2-dev libportmidi-dev
apt-get install python-numpy
pip3 install --user hg+http://bitbucket.org/pygame/pygame
If you not root user then use sudo before start every-line.

NVM fails to install any version of Node.js in Cygwin

I've already learned that Node.js opted out of supporting Cygwin in the newer version, but NVM can't install the older version either. The error I'm getting:
$ nvm install v0.4.12
Additional options while compiling:
######################################################################## 100.0%
C:\Python27\python.exe: can't open file '/home/wvxvw/.nvm/src/node-v0.4.12/tools\
/waf-light': [Errno 2] No such file or directory
nvm: install v0.4.12 failed!
(formatted for readability)
I think this is because of Python binaries aren't aware of Cygwin-style path (and cannot find /home/ directory) I tried building from sources (same version) and am facing the same problem). I'm not sure however what to do. I wouldn't like to change Python installed in Windows for Python that can be installed through Cygwin. And if this error isn't just the tip of the iceberg, I'd maybe just change the Makefile.
The question is directed to those who might tell whether it makes sense to try to "fix" the Makefile, or should I just use Cygwin's version of Python (its problem is very buggy fork, but I think I could live with that...)
Command is not correct , use version without v. Try : nvm install 0.4.12

I've installed Bottle for Python 2.7, but how to access ir from Python 3.2?

I have installed bottle on my Ubuntu Linux server using
sudo pip install bottle
and it is installed to: /usr/local/lib/python2.7/dist-packages
But I also have Python 3.2 installed on my system, and I want to access bottle from Python 3.2. Python 3.2 does not seem to recognise that bottle is installed.
What am I doing wrong?
You'd have to separately install it for Python 3.2 (with e.g. sudo pip-3.2 install bottle).
It's currently in python2.7/dist-packages, meaning that only 2.7 is going to load it. You could try to add that to your PYTHONPATH or similar, but that will very rarely work between Python 2 and 3 because the source files aren't quite compatible. (Any C extensions are also certainly not going to work, though bottle doesn't have any of those.)
Unfortunately, although that command works, it looks like the version of bottle in pypi isn't Python 3-compatible even when installed through pip-3.2:
In [1]: import bottle
File "/Library/Frameworks/Python.framework/Versions/3.2/bin/bottle.py", line 373
except re.error, e:
^
SyntaxError: invalid syntax
The homepage claims that it works with 3.x, but I got that error installing with both pip and easy_install. The latest development version, which is just a single file linked from the homepage, seems to work, though.
You are not doing anything wrong. Pip uses the /usr/bin/python by default and only installs there.
Unless you want to setup virtualenv-s, you probably best copy the current pip to pip3.2 and edit that to call python 3.2:
sudo -s -H
p=$(which pip)
cat $p | sed "1s|/usr/bin/python|$(which python3.2)|" > $p"3.2"
chmod 755 $p"3.2"
exit
You now have a pip3.2 that will install bottle so python3.2 can use it. If you get an error running pip3.2 about not finding pkg_resources look at No module named pkg_resources
I'll answer this myself. Turns out the latest release version of pip does not include pip-3.2. You need to download the development version and use that, which includes pip-3.2.
Just download it manually from offsite. It is just one file.
Place it into the lib/site-packages folder and give the file proper rights.

Homebrew failing to install postgresql; python 64-bit errors

I'm getting errors when running

to
export PATH=/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/X11/bin
And although I'm getting python 64-bit errors, my version of python is 64-bit according to this SO post:
$ python -c 'import struct;print( 8 * struct.calcsize("P"))'
64
The problem pointed out in the referenced mailing list post is that the configure step isn't impacted by the PATH here. There's a whole other mechanism used to find things to link against; see Where do I set DYLD_LIBRARY_PATH on Mac OS X for a quick intro. You could try the suggested workaround given by the brew script--rename /Library/Frameworks/Python.framework/Versions/Current/Python to something else to get it out of the linker's search path, repeat the brew install, then put it back.
If you don't need Python bindings in your PostgreSQL, you can also just install it without Python bindings using brew install postgresql --no-python.
This command is installing the server, not the python bindings. Is that what you want? There is a installer for osx that will install the server for you.
Once you have done that, you can install the psycopg2 bindings directly from source.

Setuptools not found

I am switching from Linux to OSX and when I run our build's setup.py script, I get an error message that contains the text
This script requires setuptools version 0.6c7.
I have tried several times to install setuptools, and have verified that the setuptools egg exists in /Library/Python/2.6/site-packages. I have no idea why it is not being recognized.
It is very common to have multiple versions of Python on OS X systems. In recent releases of OS X, Apple has shipped two versions itself (in /usr/bin). You may have installed more recent versions using installers from python.org (which generally exist in /Library/Frameworks/Python.framework or using a package distributor like MacPorts (which install in /opt/local/Library/Frameworks/Python.framework). Keep in mind that each version of Python requires its own copy of setuptools.
Since the site package path you report is /Library/Python/2.6/site-packages, it is most likely you have used the Apple-supplied Python 2.6.1 in OS X 10.6 to try to install a new version of setuptools. Note that Apple already supplies setuptools for its Pythons (0.6c9 for 2.6.1 in 10.6); the corresponding easy_install commands are in /usr/bin.
$ /usr/bin/python2.6 -c 'import setuptools;print(setuptools.__file__,setuptools.__version__)'
('/System/Library/Frameworks/Python.framework/Versions/2.6/Extras/lib/python/setuptools/__init__.pyc', '0.6c9')
If you are using another non-Apple-supplied Python, follow the instructions to install a new version of setuptools (or Distribute) making sure you are invoking the right version of Python. Check your shell PATH and which python to make sure.
If that doesn't help, update your question with more information.
UPDATE: Based on your further comments, it seems something was amiss in your default site-packages directory. With that problem out of the way and having established that there is an Apple-supplied setuptools version 0.6c9 installed, it appears the package you are trying to install is looking for a specific, earlier version of setuptools, 0.6c7. If that is the case, you should first determine why that is and if it is necessary. Chances are that it is just an incorrect version specification in the package's setup.py file, i.e. using == rather than >=. If you can, edit the setup.py so it can use a newer version. In the unlikely event that the package really does need that specific older version of setuptools (which may not even work with that version of Python or OS X), you could try installing the older version, like so:
$ sudo /usr/bin/easy_install-2.6 setuptools==0.6c7
$ /usr/bin/python2.6 -c 'import setuptools;print(setuptools.__file__,setuptools.__version__)'
('/Library/Python/2.6/site-packages/setuptools-0.6c7-py2.6.egg/setuptools/__init__.pyc', '0.6c7')
But you really should avoid doing that if at all possible as that will install another older version of easy_install in /usr/local/bin and could cause problems with installing and using other packages.
Have you tried to import setuptools in your setup.pyscript?
import setuptools
This solved my setuptool-ish build problems in the past.
