我有一个由诗歌创建的新项目 yolo 。
我做了以下步骤:
poetry new
poetry add requests
poetry add -D pytz
poetry add -D --optional --extras=dev ipdb
poetry lock
我的 toml 文件如下所示:
[tool.poetry]
name = "yolo"
version = "0.1.0"
description = ""
authors = ["Your Name <[email protected] /cdn-cgi/l/email-protection>"]
[tool.poetry.dependencies]
python = "^3.6"
requests = "^2.24.0"
[tool.poetry.dev-dependencies]
pytest = "^5.2"
pytz = "^2020.1"
ipdb = {version = "^0.13.3", optional = true, extras = ["dev"]}
[build-system]
requires = ["poetry>=0.12"]
build-backend = "poetry.masonry.api"
我删除了环境:
$ poetry env list
yolo-_0wi_Pw3-py3.6 (Activated)
$ poetry env remove yolo-_0wi_Pw3-py3.6
Deleted virtualenv: .cache/pypoetry/virtualenvs/yolo-_0wi_Pw3-py3.6
现在如果我尝试这样做:
$ poetry install
Creating virtualenv yolo-_0wi_Pw3-py3.6 in .cache/pypoetry/virtualenvs
Installing dependencies from lock file

- Installing pytest (5.4.3)
- Installing pytz (2020.1)
- Installing requests (2.24.0)
- Installing yolo (0.1.0)
正如预期的那样,没有 ipdb。
但如果我尝试:
$ poetry install --extras='dev'
Installing dependencies from lock file
[ValueError]
Extra [dev] is not specified.
为了澄清和解释更多。
我的问题中生成的 Toml 文件是诗歌的自动作品,有一个修复需要手动干预。
[tool.poetry]
name = "yolo"
version = "0.1.0"
description = ""
authors = ["Your Name <[email protected] /cdn-cgi/l/email-protection>"]
[tool.poetry.dependencies]
python = "^3.6"
requests = "^2.24.0"
[tool.poetry.dev-dependencies]
pytest = "^5.2"
pytz = "^2020.1"
ipdb = {version = "^0.13.3", optional = true, extras = ["dev"]}
[tool.poetry.extras]
dev = ["ipdb"]
[build-system]
requires = ["poetry>=0.12"]
build-backend = "poetry.masonry.api"
不用说,这真是令人困惑。
但从现在开始,如果我们这样做:
$ poetry install -E dev
它将按预期工作并且将安装 ipdb。
