I have to use a proxy, which I have configured in the .condarc file, for conda work, which works perfectly fine. However when I'm setting up a new python environment with an environment.yml file, which could look like this:

```
name: Test
channels:
  - intel
  - defaults
dependencies:
  - pypdf2=1.26.0=py36_1
  - mkl=2018.0.2=1
  - pip:
    - adjusttext==0.7.2
prefix: C:\ProgramData\Anaconda3\envs\Test

```

Pip doesn't use the provided proxy to install those packages, so I get an error. How can I get pip to use that proxy as well?
