运行docker和poem时出现ModuleNotFoundError

Question

我在尝试运行容器时遇到错误，提示在尝试导入时找不到模块。具体来说：

ModuleNotFoundError: No module named 'sentry_sdk'

以下是我的DockerFile，它是多阶段构建的，似乎根据控制台输出安装了所有包。

我的主文件的开头如下：

from logging import getLogger
from os import environ
from typing import List

from fastapi import FastAPI
from starlette.status import HTTP_200_OK
from sentry_sdk import init as SentryInit
from sentry_sdk.integrations.asgi import SentryAsgiMiddleware
from sentry_sdk.integrations.sqlalchemy import SqlalchemyIntegration

线路失败：

从sentry_sdk导入init作为SentryInit

这是第一行，其中包不是容器上的默认安装，因此这可能与 venv 有关，但我不确定原因或方式。

我的 pyproject.toml 看起来像这样：

[tool.poetry]
authors = ["xxx"]
name = "xxx"
description = "xxx"
version = "xxx"

[tool.poetry.dependencies]
asyncpg = "^0.21.0"
fastapi = "^0.73.0"
pydantic = "^1.9.0"
python = "^3.8.7"
sqlalchemy = "^1.3.22"
databases = "^0.5.5"
sentry-sdk = "^1.5.5"

[tool.poetry.dev-dependencies]
pytest = "^3.4"
httpx = "^0.22.0"

[build-system]
build-backend = "poetry.core.masonry.api"
requires = ["poetry-core>=1.0.0"]

Answer 1

好吧，我明白了，但现在我觉得很愚蠢。

问题确实与 venv 有关，基本上，uvicorn 安装在基础映像上，但没有安装在我的 pyproject.toml 中。所以诗歌没有把它安装在venv中。当我使用 CMD 在 Dockerfile 中启动应用程序时，它在 venv 中找不到 uvicorn，因此转到基本安装并从那里运行。当我将 uvicorn 添加到 venv 时，一切正常。

Answer 2

提供答案的上下文，以下是您需要运行的命令：

poetry add uvicorn
poetry lock
