是诗歌忽略了附加内容,还是pyproject.toml配置错误?

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

Package operations: 17 installs, 0 updates, 0 removals

  - Installing wcwidth (0.2.5)
  - Installing zipp (3.2.0)
  - Installing importlib-metadata (2.0.0)
  - Installing pyparsing (2.4.7)

  - Installing pytest (5.4.3)
  - Installing pytz (2020.1)
  - Installing requests (2.24.0)
  - Installing yolo (0.1.0)

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。

1 个答案:

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。
