问题

对于我的Python包'imfp'，我正在使用'Github Actions'通过'poetry'和pytest在虚拟环境中进行构建和测试。奇怪的是，'pytest --version'命令可以正常工作，显示'pytest 7.2.2'。然而，'pytest tests'返回错误，显示'pytest: command not found'。

根据Substack上其他帖子中的建议，我还尝试了以下命令：

py.test tests
py.test: command not found

python -m pytest tests
No module named pytest

py -m pytest tests
No module named pytest

python3 -m pytest tests
No module named pytest

这是我的Github Actions脚本：

name: build-test

on:
push:
branches: [main, master]
pull_request:
branches: [main, master]

jobs:
build:
strategy:
fail-fast: false
matrix:
python-version: ["3.11"]
poetry-version: [latest]
os: [windows-latest]
defaults:
run:
shell: bash
runs-on: ${{ matrix.os }}
steps:
- uses: actions/checkout@v3
- uses: actions/setup-python@v4
with:
python-version: ${{ matrix.python-version }}
- name: Install and configure Poetry
uses: snok/install-poetry@v1
- name: Configure Poetry
run: |
poetry config virtualenvs.in-project true
- name: Install project
run: |
poetry install --no-interaction
- name: Activate venv windows
run: |
source .venv/scripts/activate
pytest --version
if: runner.os == 'Windows'
- name: Activate venv other
run: |
source .venv/bin/activate
pytest --version
if: runner.os != 'Windows'
- name: Run tests
run: |
python3 -m pytest tests/

请注意，据我所知，这个问题不是重复的。大多数类似的帖子涉及到'pytest --version'的失败，但在这种情况下，该命令可以正常工作。

根据jobs.<job_id>.steps[*].run：

每个 run 关键词表示在运行环境中启动一个新的进程和shell。

因此，在上一步中激活的 venv 在下一步中不会保持激活状态。

在运行测试之前，需要再次激活它。

激活虚拟环境并不总是必要的。您还可以直接调用虚拟环境中的二进制文件，分别位于虚拟环境的二进制文件目录中（在Windows上为Scripts，在其他地方为bin）。例如：.venv/Scripts/python -m pytest。

或者，由于使用了Poetry，您还可以调用poetry run python -m pytest（这可能是最佳解决方案，在使用Poetry时一直使用poetry run）。
