使用天蓝色管道和诗歌，有什么方法可以避免在每个脚本中采购 ~/.poetry/env ？

Question

我目前使用下面的脚本来构建我的包并将其发布到私有 Azure Artifacts 源。在每个脚本中，我都必须运行该行source $HOME/.poetry/env，否则它找不到诗歌命令。

有没有办法消除这种重复？

完整脚本：

trigger:
- master

pool:
  vmImage: 'ubuntu-latest'

strategy:
  matrix:
    Python38:
      python.version: '3.8'

steps:
- task: UsePythonVersion@0
  inputs:
    versionSpec: '$(python.version)'
  displayName: 'Use Python $(python.version)'

- script: |
    sudo apt-get install texlive texlive-latex-extra latexmk
    python -m pip install --upgrade pip
    python -m pip install keyring artifacts-keyring
    curl -sSL https://raw.githubusercontent.com/python-poetry/poetry/master/get-poetry.py | python
    source $HOME/.poetry/env
    poetry install
  displayName: 'Install package and tools'

- script: |
    source $HOME/.poetry/env
    poetry run python -m isort -rc
    poetry run python -m black -l 79 .

- script: |
    source $HOME/.poetry/env
    poetry run python -m pytest tests/
  displayName: 'Test code'

- script: |
    source $HOME/.poetry/env

    poetry config repositories.azure https://pkgs.dev.azure.com/MY_USERNAME/preppy/_packaging/builds/pypi/upload
    poetry publish -r azure --username=$(pipelines-token) --password=$(pipelines-token)
    exit 0

source $HOME/.poetry/env仅适用于当前 shell。您需要在PATH代理系统中设置Poetry的bin目录（$HOME/.poetry/bin）。

请添加echo "##vso[task.setvariable variable=PATH]${PATH}:$HOME/.poetry/bin"您的第一个脚本任务以设置$HOME/.poetry/bin系统 PATH 变量的路径。那么您就不需要source $HOME/.poetry/env再添加以下脚本任务了。请检查下面的示例。

echo "##vso[task.setvariable...."仅在以下任务中生效。

因此，您仍然需要在第一个脚本任务中使用“source $HOME/.poetry/env”。

请检查在脚本中设置变量以获取更多信息。

- script: |
    curl -sSL https://raw.githubusercontent.com/python-poetry/poetry/master/get-poetry.py | python

    #below script will only take effect in the following tasks. 
    #So you still need to use "source $HOME/.poetry/env" in the first script task.

    echo "##vso[task.setvariable variable=PATH]${PATH}:$HOME/.poetry/bin" 
    source $HOME/.poetry/env

    poetry install
  displayName: 'Install package and tools'

- script: |
    poetry --version
  condition: always()
