### Using pip to get cache location
> Note: This requires pip 20.1+
```yaml
- name: Get pip cache dir
id: pip-cache
run: |
echo "::set-output name=dir::$(pip cache dir)"
- name: pip cache
uses: actions/cache@v1
with:
path: ${{ steps.pip-cache.outputs.dir }}
key: ${{ runner.os }}-pip-${{ hashFiles('**/requirements.txt') }}
restore-keys: |
${{ runner.os }}-pip-
```
### Using a script to get cache location
> Note: This uses an internal pip API and may not always work
```yaml
- name: Get pip cache
- name: Get pip cache dir
id: pip-cache
run: |
python -c "from pip._internal.locations import USER_CACHE_DIR; print('::set-output name=dir::' + USER_CACHE_DIR)"
