Environment data

• VS Code version: 1.24.1
• Extension version: 2018.5.0
• OS and version: Windows 10
• Python version: Anaconda (conda 4.5.4, Python 3.6.5)
• Type of virtual environment used: conda
• Relevant/affected Python packages and their versions: none

Actual behavior

The extension offers to install pylint for me. I click "Install" and the popup asks me whether I want to install it using conda or pip. I choose conda. The installation fails (see below for the output log).

Expected behavior

The installation succeeds.

Steps to reproduce:

1. Create a conda environment with a name containing at least one whitespace
2. Activate this conda environment in Visual Studio Code
3. Choose to install pylint using conda when prompted to by the extension

One can see in the output below that while the activate command properly handles the whitespace in the environment name, the conda install command does not.
