dear experts - hello to you, 

 

i am currently preparing my Asus Notebook for the installation of a Python-development environment. 

 

the prelimininary things i do are the following tests and here is what i have encountered. 

 

note: i am on MX-Linux: 

  

martin@MartinsMX-Rechner:~
$ python --version
Python 2.7.13
martin@MartinsMX-Rechner:~
$ uname -a
Linux MartinsMX-Rechner 4.19.0-5-amd64 #1 SMP Debian 4.19.37-2~mx17+1 (2019-05-15) x86_64 GNU/Linux
martin@MartinsMX-Rechner:~
$

 

 

well - i guess that i have to 

 

- renew the python version

- have a closer look at the MX-version ( - actual version is 19.1

 

then i should do the following:  

 

to setup pipenv to run and work with Python.

 

i read the following docs: cf. python-guide.org/dev/virtualenvs/

Make sure you’ve got Python & pip
Before you go any further, make sure you have Python and that it’s available from your command line. You can check this by simply running:

$ python --version
You should get some output like 3.6.2. If you do not have Python, please install the latest 3.x version from python.org or
 refer to the Installing Python section of this guide.


the question is: How do I setup pipenv to use Python 3.6 when my system does not have python 3.6?

 

  

$ pipenv --python 2.7.1.3
Warning: python 2.7.1.3 was not found on your system…


You can specify specific versions of Python with:

  

  $ pipenv --python path/to/python

 

i guess - that i either sensu python-guide.org/dev/virtualenvs/ can work on the issues: 


- either i can manually write the version i need in the according Pipfile: 

[requires]
python_version = "2.7.1.3"

 

Or i can install it on my system. But I guess we will need the version to be installed if we plan to actually run pipenv install.

therefore i think that i should go ahead and use pyenv sensu: https://github.com/pyenv/pyenv.

i think that i have to follow the installation instructions, then afterwards installing Python 2.7.1.3. is just a matter of 

  

pyenv install 2.7.1.3

Then i can set the order of preference with 

pyenv global system 2.7.1.3

Besides, if pyenv is available, pipenv will automatically use it to install the required version. From the pipenv README: it says 

 

Automatically install required Pythons, if pyenv is available.

This does a user installation to prevent breaking any system-wide packages. If pipenv isn’t available in your shell after installation, you’ll need to add the user base’s binary directory to your PATH.
On Linux and macOS you can find the user base binary directory by running python -m site --user-base and adding bin to the end. For example, this will typically print ~/.local (with ~ expanded to the absolute path to your home directory) so you’ll need to add ~/.local/bin to your PATH. You can set your PATH permanently by modifying ~/.profile.
On Windows you can find the user base binary directory by running py -m site --user-site and replacing site-packages with Scripts. For example, this could return C:\Users\Username\AppData\Roaming\Python36\site-packages so you would need to set your PATH to include C:\Users\Username\AppData\Roaming\Python36\Scripts. You can set your user PATH permanently in the Control Panel. You may need to log out for the PATH changes to take effect.

 

 

Well - i am on MX-Linux and i want to set up the environment on a linux-machine.

 

what do you say...?

 

 

Look forward to hear from you

The virtual environment was not created successfully because ensurepip is not

    apt-get install python3-venv

You may need to use sudo with that command.  After installing the python3-venv

you see - exactly in the last part - i have issues:

The process might go something like this:

 

$ cd ~
$ mkdir pythonroot
$ mkdir opt
$ mkdir app
$ cd opt
$ wget <python tarball>
$ tar -xvf <python tarball>
$ cd python-3.6
$ ./configure --prefix="$HOME"/pythonroot
$ make
$ make install
$ cd ~
$ cd app
$ virtualenv venv --python ~/pythonroot/bin/python
$ . venv/bin/activate
[venv]$ which python
/home/<user>/pythonroot/bin/python

Perhaps I'm wrong, but that last part has it explained clearly. You need to write the following command: 

sudo apt-get install python3-venv

Looking through all of your above posts here, I can't find one use of sudo before executing the command. Unless python3-venv is already installed on your machine?

 

With that said, I'm not an expert at Linux.

[venv]$ which python
/home/<user>/pythonroot/bin/python

------------------------------------------------

suspect that python3 or python is not working properly and this is the cause of the problem

suspect that Node.js needs updating |which is needed for the codium to be used as intended

------------------------------------------------
Updating all packages (OS and other installed packages)
apt-get install update &&
apt-get install upgrade

Updating all packages (OS and other installed packages)
sudo apt update && sudo apt -y full-upgrade

------------------------------------------------
this works if python works normally?
------------------------------------------------

This will break scripts, but is exactly the way to change python. You should also rewrite the scripts to not assume python is 2.x. This will work regardless of the place where you call system or exec.

sudo mv / usr / bin / python / usr / bin / python2
sudo ln -s $ (which python3) / usr / bin / python

------------------------------------------------
python3 -m pip install --user --upgrade pip
python3 -m pip --version
python3 -m pip install --user virtualenv
python3 -m venv env

------------------------------------------------
sudo apt install python-pip
sudo apt install python3-venv python3-pip

this will work if python is working

------------------------------------------------

works for python3 and newer python versions

curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
python get-pip.py

------------------------------------------------

for old python2.6
curl https://bootstrap.pypa.io/2.6/get-pip.py -o get-pip.py
python get-pip.py
------------------------------------------------
which python
which python3

------------------------------------------------
Check the execution path of python3 where it has libraries
which python3
which python

------------------------------------------------
open bash_profile file and add an alias
nano ~ / .bash_profile
alias python = '/ usr / local / bin / python3' or alias python = '/ usr / bin / python3'

python --version
------------------------------------------------

do these commands work?

------------------------------------------------

does this command work

------------------------------------------------

Python 2
sudo apt install python-pip
------------------------------------------------

Python 3
sudo apt install python3-venv python3-pip

------------------------------------------------

 

Node.js LTS (12.x)

# As root
curl -sL https://rpm.nodesource.com/setup_lts.x | bash -
apt-get install -y nodejs

 

# No root privileges 
curl -sL https://rpm.nodesource.com/setup_lts.x | sudo bash -
sudo apt-get install -y nodejs

 

Node.js Current (14.x)

# As root
curl -sL https://rpm.nodesource.com/setup_current.x | bash -
apt-get install -y nodejs

 

# No root privileges 
curl -sL https://rpm.nodesource.com/setup_current.x | sudo bash -
sudo apt-get install -y nodejs
