Brief Introduction

---

When using Anaconda, one needs to be aware of the environment that one is working.

Then, in Anaconda Prompt one needs to use the following code:

conda $command -n $ENVIRONMENT_NAME $IDE/package/module

$command - Command that I intend to use (consult documentation for general commands)

$ENVIRONMENT NAME - The name of your environment (if one is working in the root, conda $command $IDE/package/module is enough)

$IDE/package/module - The name of the IDE or package or module

Solution

---

If one wants to install it in the root and one follows the requirements - (Python (>= 2.7 or >= 3.4), NumPy (>= 1.8.2), SciPy (>= 0.13.3).) - the following will solve the problem:

conda install scikit-learn

Let's say that one is working in the environment with the name ML.

Then the following will solve one's problem:

conda install -n ML scikit-learn

Note: If one need to install/update packages, the logic is the same as mentioned in the introduction. If you need more information on Anaconda Packages, check the documentation.
