诗歌安装| SolverProblemError 因为 my_project 依赖于与任何版本都不匹配的字符串 (*)，所以版本求解失败

Question

我还没有使用诗歌来运行项目，所以请原谅缺乏理解。

\n

我成功安装了诗歌Python库管理器，使用：

\n

curl -sSL https://raw.githubusercontent.com/python-poetry/poetry/master/get-poetry.py | python3\n

\n

下一步poetry install最初返回此错误：

\n

me@LAPTOP-G1DAPU88:~/.ssh/workers-python/workers$ poetry install\n\n  RuntimeError\n\n  Poetry could not find a pyproject.toml file in /home/me/.ssh/workers-python/workers or its parents\n\n  at ~/.poetry/lib/poetry/_vendor/py3.8/poetry/core/factory.py:369 in locate\n      365\xe2\x94\x82             if poetry_file.exists():\n      366\xe2\x94\x82                 return poetry_file\n      367\xe2\x94\x82\n      368\xe2\x94\x82         else:\n    \xe2\x86\x92 369\xe2\x94\x82             raise RuntimeError(\n      370\xe2\x94\x82                 "Poetry could not find a pyproject.toml file in {} or its parents".format(\n      371\xe2\x94\x82                     cwd\n      372\xe2\x94\x82                 )\n      373\xe2\x94\x82             )\n

\n

我很快意识到我需要自己制作的pyproject.toml文件。poetry install再次运行得到：

\n

$ poetry install\n\n  TOMLError\n\n  Invalid TOML file /home/me/.ssh/workers-python/workers/pyproject.toml: Key "json " already exists.\n\n  at ~/.poetry/lib/poetry/_vendor/py3.8/poetry/core/toml/file.py:34 in read\n      30\xe2\x94\x82     def read(self):  # type: () -> "TOMLDocument"\n      31\xe2\x94\x82         try:\n      32\xe2\x94\x82             return super(TOMLFile, self).read()\n      33\xe2\x94\x82         except (ValueError, TOMLKitError) as e:\n    \xe2\x86\x92 34\xe2\x94\x82             raise TOMLError("Invalid TOML file {}: {}".format(self.path.as_posix(), e))\n      35\xe2\x94\x82\n      36\xe2\x94\x82     def __getattr__(self, item):  # type: (str) -> Any\n      37\xe2\x94\x82         return getattr(self.__path, item)\n      38\xe2\x94\x82\n

\n

上述错误表明存在重复条目。

\n

poetry install使用现在更新的pyproject.toml文件再次运行会cwd引发此错误（在帖子的标题中）：

\n

$ poetry install\nCreating virtualenv my_project-1_EUeV5I-py3.8 in /home/me/.cache/pypoetry/virtualenvs\nUpdating dependencies\nResolving dependencies...

\n

然而，暂时删除所有实例给了我这个on ...= "*"的错误，但它似乎不存在：\\nline 12

\n

我已经恢复了这个。

Answer 1

作为一般建议，我建议使用诗歌的命令行而不是创建/操作pyproject.toml.

以poetry init或开头poetry init -n，并使用 添加依赖项poetry add。

当前的问题pyproject.toml是，您将内置包声明为依赖项，例如 os、pathlib、string 等。这就是您收到消息的原因Because my_project depends on string (*) which doesn't match any versions, version solving failed.，这意味着诗歌在存储库中找不到任何匹配的包信息。

Answer 2

删除旧的诗歌锁已经为我解决了
