Python 2 has been EOL'd and is no longer receiving security updates. You can read more about this here:
Python 2 is still available on DreamHost servers, however, it's recommended you upgrade to Python 3 to ensure your applications are secure going forward.
Due to a Linux Kernel upgrade, installing a version of Python lower than 2.7.15 will fail on all DreamHost servers. If you need to install a custom version of Python, make sure it's newer than version 2.7.15.
If you'd like to install a version of Python3, view the following article:
Configuring an SSH user
To run the commands in this article, you must log into your server via SSH with your Shell user. View the following articles for more information:
- Log into your server via SSH, and then run the following commands one at a time:
[server]$ cd ~ [server]$ mkdir tmp [server]$ cd tmp [server]$ wget http://www.python.org/ftp/python/2.7.15/Python-2.7.15.tgz [server]$ tar zxvf Python-2.7.15.tgz
[server]$ cd Python-2.7.15
[server]$ ./configure --prefix=$HOME/opt/python-2.7.15 --with-ensurepip=install [server]$ make [server]$ make install
- These commands install your local version of python to /home/<username>/opt/python-2.7.15.
- Navigate back to your home directory:
[server]$ cd ~
- View the creating and editing a file via SSH article for instructions on how to edit your existing .bash_profile. To add a path in order to use the new version of Python over the system default, enter the following line:
- Save and close the file and return to your shell.
- Run the following command to allow your current Shell session to use the specified version of Python 2:
[server]$ . ~/.bash_profile
- Check which version of Python you're now using by entering the following command:
[server]$ which python
- It should respond with this:
If it responds with a path like
/usr/bin/python, then the newly downloaded copy is not being used. Most often this is due to the .bash_profile not being updated correctly. Try logging out and back in again. If necessary, repeat the steps above.
