By default python 2.7 was installed on this OS, which can be accessed using the python command. I installed python33 on it, using this tutorial:
https://devops.profitbricks.com/tutorials/install-python-3-in-centos-7/
Now, the python33 package is installed, but I cannot access it. I have tried the python33 command. I've also tried these:
find -name python33
which python33
rpm -ql python33
But I get nothing. What should I do?
that's because python didn't installed in /usr/bin/.
it installed on /opt/rh/python33/root/usr/bin/
Python 3.3 will become accessible by launching a new shell instance using the Software Collection scl command :
scl enable python33 bash
The command itself is likely just python3
To check to see if it is installed do:
sudo yum info python3
if it isn't, use:
sudo yum install python3
I believe the only 3.x version available is 3.4, but I don't imagine you'll run into any version conflicts with what you are doing.
edit:
If it is installed, it might be python3.3, not python33

I am trying to install azure-cli on centos 7 box. I am getting this error repeatedly
Error: Package: azure-cli-2.0.80-1.el7.x86_64 (azure-cli)
Requires: libpython3.6m.so.1.0()(64bit)
You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest
I tried to execute both commands but none of these worked for me.
Acturally, Azure CLI requires python3, it's even an executable Python package azure-cli which you can find in PyPI.org. So please make sure there is a Python 3 runtime installed in your CentOS 7.
If you want to fix your issue manually, you can try to download and install the related rpm package for Libpython3.6m.so.1.0()(64bit) from https://pkgs.org/download/libpython3.6m.so.1.0()(64bit), as the figure below.
However, the best way is to follow the offical tutorial Install Azure CLI with yum to install it in CentOS 7.
Otherwise, the other solution is as below to directly install its python package via pip.
Please check whether the Python 3 runtime had been installed in CentOS 7 via command python3 -V or python -V to see the Python version or system will remind you to install it.
Please check whether the pip or pip3 command for Python 3 runtime had been installed via pip3 -V or pip -V to see the pip version or system will remind you to install it.
Completed the two steps above, you can easily to install azure-cli via command sudo pip3 install azure-cli or sudo pip install azure-cli, it will help to install azure-cli to the system path, then you can try to use it via az --version.
You can install it by mentioning the repo/package URL
sudo yum install https://packages.microsoft.com/yumrepos/azure-cli/azure-cli-2.38.0-1.el7.x86_64.rpm
packages can be found here https://packages.microsoft.com/yumrepos/azure-cli/
I installed python 3x via home brew, the process was successful.
However when I check version, it shows 2x
here is the terminal output
➜ ~ brew install python
Warning: python 3.7.2 is already installed, it's just not linked
You can use `brew link python` to link this version.
➜ ~ brew link python
Linking /usr/local/Cellar/python/3.7.2... Error: Permission denied # dir_s_mkdir - /usr/local/Frameworks
➜ ~ sudo brew link python
Error: Running Homebrew as root is extremely dangerous and no longer supported.
As Homebrew does not drop privileges on installation you would be giving all
build scripts full access to your system.
➜ ~ python -V
Python 2.7.10
I think I need to modify some kind of path. And do some magic then pray...lol
Anyway anyone know how to get this work on my machine? I'm mac latest
First, solve your permission problem by running the official command from the Homebrew Documentation, Troubleshooting page
cd /usr/local && sudo chown -R $(whoami) bin etc include lib sbin share var opt Cellar Caskroom Frameworks
Then run brew link python
And finally run echo $PATH and check that your /usr/local/bin has precedence over other directories.
you could do brew uninstall python3 and install it from the python website here https://www.python.org/
When you go install a module you do pip3 install packageName
And when you run a program you could run it from your IDE (I recommend VSCode) or run it from the terminal with python3 drag_python_file_here
you have to use python3 instead of python on Mac so like python3 path/to/file.py and pip is now pip3 so like pip3 install pillow
I followed installment instructions mentioned here
Its a simple pip install command
After that I went to my linux terminal and wrote in2csvbut got the following error:
/usr/bin/in2csv: No such file or directory
Originally I tried to install it using the command:
sudo apt-get install python3-csvkit
And the in2csv command used to work on terminal, but it appears to work under python 3 installation and I need it under my python2.7.
so I uninstalled the python3-csvkit, and installed it again using pip install, but again its not working from terminal, this way.
Any ideas why, and how to solve it?
in2csv command manual: here
I just had this problem and solved with:
sudo pip install csvkit
Without the sudo pip installs csvkit in /home/username/.local/lib/python2.7/site-packages and probably puts the executable in /home/username/.local/bin. You could avoid the sudo by adding that to your shell PATH.
Our server OS is CentOS 6.8, I was trying to install google-cloud-sdk, even though I installed
python 2.7 in /usr/local/bin
, it is still looking at old version of
python 2.6 in /usr/bin
. I tried giving export PATH=/usr/local/bin:$PATH to first look at /usr/local/bin than /usr/bin but still the problem persists. please suggest a way to fix.
The way I have solved this (and I know it works) is to first install Python 2.7 in whatever way you'd like, then install pip using Python 2.7 which will give you pip2.7. You can then use pip2.7 to install the google_compute_engine module so that it ends up in the right modules folder.
# get pip2.7
wget https://bootstrap.pypa.io/get-pip.py
python2.7 get-pip.py
# install the gcloud module
pip2.7 install google_compute_engine
You can then add this to your $HOME/.bashrc
export CLOUDSDK_PYTHON=/usr/local/bin/python2.7
This is the best repeatable way I know of
Go to the google-cloud-sdk folder and open the install.sh file.
Change the CLOUDSDK_PYTHON="python" value to CLOUDSDK_PYTHON="python2.7"
Rerun the install with the command:
./install.sh
Or you could install it using yum:
https://cloud.google.com/sdk/downloads#yum
If you are on Windows This is a simple solution that worked for me:
open Powershell as administrator and run this to add your Python folder to your environment's PATH:
$env:Path += ";C:\python27_x64\"
Then re-run the command that gave you the original error. It should work fine.
Alternatively you could run that original (error-causing) command within the Cloud SDK Shell. That also worked for me.
I found a CLOUDSDK_PYTHON inside my ~/.bash_profile (or ~/.zshenv).
I removed it, and went back into my google-cloud-sdk directory and reinstalled it.
./install.sh
This fixed the issue for me.
I'm currently migrating to new computer and I need to reinstall the software I am using which are:
Python 3.3,
Lighttpd (newest version),
Pymongo (newest version),
Ubuntu 12.04 Desktop (The System I'm using)
I started to install Python 3.3 by downloading it from the its official website (in tar.bz2 file) and by following this tutorial. Afterwards I installed Lighttpd and changed the lighttpd.conf for Python by following this tutorial, too.
I tried several paths for my cgi.assign, none of them worked. Especially /opt/python3.3/bin/python3.3 should be working, but it shows 500 - internal Server error all the time with a "hello world" test script.
Now regardless to this problem I have no clue on installing Pymongo. If I try to intall pip OR easy_install python3.3 I have to manually download it and execute the setup.py with my python3.3 executable, right? Because this always fails with an error:
`Error missing zlib on a bundle called distribute-0.7.3 (is this even the right tool I need, because it seems to be a legacy wrapper !?) or unknown url type: https for pymongo2.6.2 itself.`
I'm getting crazy with this setup. Why is this so difficult to handle? Other programs are just a few clicks to install even on a system like Ubuntu, but these particular development tools seem to be really difficult to install.If anybody has an idea on how to install all three together or has information on a better solution please help me out.
The system is used to program Python scripts in Eclipse and trying them out directly on the system (lighttpd). The database used is MongoDB. Python and MongoDB are communicating over the Pymongo driver. I am planning to use the system on a Server distribution on release and it has to be nicely scalable on a high amount of excecutions.
Thanks for your time,
It's easiest to use the Ubuntu repositories:
sudo apt-get update
sudo apt-get install python3 python3-pip lightppd python-pymongo
Or if that only installs the python2.x pymongo, use pip, which you've just installed:
sudo pip-3.3 install pymongo
Or better yet, use a virtualenv with the help of virtualenvwrapper (docs)
sudo pip install virtualenvwrapper
... # follow instructions for installing virtualenvwrapper
mkvirtualenv --python=/usr/bin/python3 -i pymongo mongoppd
workon mongoppd
... which will segregate the environment I've called 'mongoppd' from the rest of your system so you can't cause any trouble. Then you don't need sudo to pip-3.3 install things, just workon mongoppd then pip-3.3 install [...]. Or after the -i flag when you create the virtualenv to get it installed straight away.
In general, on Ubuntu, you should hardly ever have to install something manually. Your first attempt should be using sudo apt-get install (use tab-complete to see what's available or just google "ubuntu 12.04 packages [...]" and you'll find the list of packages). Then for python use pip install or pip-3.3 install as appropriate. You'll only need to run python setup.py install if you need to install a development version of a package or something obscure that's not on pip. I don't think there's a good reason to ever use easy_install these days.
