我有诗歌创作的新项目yolo。
我确实遵循了以下步骤:
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:
[tool.poetry]
name = "yolo"
version = "0.1.0"
description = ""
authors = ["Your Name <you@example.com>"]
[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

没有ipdb,符合预期。
但是,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,并且有一个需要人工干预的修复程序。
[tool.poetry]
name = "yolo"
version = "0.1.0"
description = ""
authors = ["Your Name <you@example.com>"]
[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。
但是从现在开始,如果这样做:
$ poetry install -E dev
它将按预期运行,并且将安装ipdb。
答案 0 :(得分:0)
花一些时间我和我的朋友我们知道发生了什么事。
操作时:
poetry install --extra=dev ipdb
实际上发生的事情是,您指定要让ipdb使用应该或不可以使用的额外“ dev”。
因此在toml中将被声明为:
[tool.poetry.dev-dependencies]
ipdb = {version = "^0.13.3", extras = ["dev"]}
实际上,我要实现的是指定存在yolo项目的额外功能,这称为dev并包括安装ipdb。这是通过在诗歌中添加新的章节来实现的:
[tool.poetry.extras]
dev = ["ipdb"]
令人困惑的因素是两者都使用额外的关键字,而上下文却完全不同。而且主包extra的样式也不同于Extra作为依赖项定义的一部分。
