   If the private repository uses a custom SSL certificate that is installed on the platform, you may see an error similar to the following:
   <pre class="terminal">
  -Could not fetch URL <span>https:</span>//example.com/api/pypi/ext_pypi/simple/fixtures/:
  +Could not fetch URL <span>https:</span>//example.com/api/pypi/ext\_pypi/simple/fixtures/:
   There was a problem confirming the ssl certificate:
  -[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:777) - skipping
  +[SSL: CERTIFICATE\_VERIFY\_FAILED] certificate verify failed (\_ssl.c:777) - skipping
   </pre>
   
   This error occurs because `pip` does not use system cerificates by default.

  ## <a id='private-repos'></a> Private Dependency Repository
  
  If you deploy apps in an environment that needs to use a private dependency
  repository, add the URL of the repository to the `requirements.txt` file in the
  following format:
  
  ```
  
negative.code:   PIP_CERT: /etc/ssl/certs/ca-certificates.crt
  ```
  
  ### <a id='private-repos-conda'></a> Conda
  
  To install dependencies using Conda, add a `channels` block to the `environment.yml` file.
  
  In the `channels` block, list custom channels and add `nodefaults`. Specifying `nodefaults` tells Conda to only use the channels in the channels block.
  
  For example:
  
  ```
  channels:
    - https://conda.example.com/repo
    - nodefaults
  ```
  
  If the private repository uses a custom SSL certificate that is installed on the platform, you may see an error similar to the following:
  <pre class="terminal">
  Error: Connection error: [SSL: CERTIFICATE\_VERIFY\_FAILED] certificate verify failed (\_ssl.c:581):
  </pre>
  
  This error occurs because `conda` does not use system certificates by default.
  To resolve this issue, set the `CONDA_SSL_VERIFY` environment variable in the `manifest.yml` file to point to the system certificate store.
  
  For example:
  
  ```
  ---
  env:
    CONDA_SSL_VERIFY: /etc/ssl/certs/ca-certificates.crt
  ```
  
  ## <a id='cfenv'></a> Parse Environment Variables
  
  The `cfenv` package provides access to Cloud Foundry application environment settings by parsing all the relevant environment variables. The settings are returned as a class instance. See [https://github.com/jmcarp/py-cfenv](https://github.com/jmcarp/py-cfenv) for more information.
