| # Third-Party Code |
| |
| This directory contains third party code licensed separate from the rest of the repository. See individual files for licensing details. |
| |
| These are libraries that are required but not provided by AppEngine. |
| |
| ## Adding and Upgrading |
| |
| The `requirements.txt` file contains a list of versioned dependencies. Add or upgrade packages as follows, |
| |
| 1. Add the new package or upgrading an existing package version in the `requirements.txt` file. |
| 2. Remove the old package directories from the `third_party` directory. *This step may not be needed depending on your version of pip. There is a [bug](https://github.com/pypa/pip/issues/1489) in some versions of `pip` that causes problems with in-place upgrades.* |
| 3. Install the dependencies by running the following command from the `third_party` parent directory, |
| |
| ``` |
| pip install --target=third_party --upgrade -r third_party/requirements.txt |
| ``` |
| |
| 4. After the upgrade is complete you should commit all directories and files that were added/changed in the `third_party` directory. |
