Github Action/Ubuntu:添加到PYTHONPATH

Question

在Github工作流main.yml上，我做了以下添加到PYTHONPATH的操作

PWD=$(pwd)
export PYTHONPATH=$PWD/src:$PWD/tests:$PYTHONPATH

我使用以下命令验证了PYTHONPATH

echo "PYTHONPATH=$PYTHONPATH"

输出为PYTHONPATH=/home/runner/work/my_api/my_api/src:/home/runner/work/my_api/my_api/tests

我有一个叫做my_api生活在/home/runner/work/my_api/my_api/src下的模块

但现在我得到了ModuleNotFoundError: No module named 'my_api'，似乎出口PYTHONPATH对系统没有任何影响。下面是完整的工作文件YML文件。

          echo "-----ls-----"
          ls

          echo "-----ls src/-----"
          ls src/

          echo "----PYTHONPATH------"
          PWD=$(pwd)
          export PYTHONPATH=$PWD/src:$PWD/tests:$PYTHONPATH
          echo "PYTHONPATH=$PYTHONPATH"

          echo "-----HISTORIC PATH----"
          export HISTORIC_DATA_FOLDER=/home/runner/work/my_api/my_api/my_api_historic_data_test
          echo "HISTORIC_DATA_FOLDER=$HISTORIC_DATA_FOLDER"

        run: |
          sleep 30
          pip install requests
          sudo python -m unittest discover

正如在评论中已经说过的，每个step都运行在自己的shell中。您需要确保正确导出变量，以便在随后的所有步骤中都可用。

echo "PYTHONPATH=$PYTHONPATH" >> $GITHUB_ENV
