如何通过pip安装Yotta

Question

我无法在 Windows 11 系统上安装 Yotta。我已经安装了依赖项，但是当我在 python 3.12、pip 版本 24.0 上执行以下命令时，它失败了。

pip install -U yotta

我收到的错误消息似乎与 python PyYAML 模块有关，但我不确定如何。这是消息：

Collecting pyyaml<6.0,>=5.1 (from valinor<2.0,>=1.1.4->yotta)

Answer 1

该问题似乎与安装 yotta 时的 PyYAML 依赖关系有关。 首先阅读整个答案。然后尝试以下操作。

首先，尝试单独安装 PyYAML 以确保其安装正确：

pip install pyyaml==5.4.1

成功安装 PyYAML 后，尝试再次安装 yotta。

pip install -U yotta

如果它不适合你，那么创建一个虚拟环境并激活它：

python -m venv yotta-env
yotta-env\Scripts\activate

升级 pip 和 setuptools：

pip install --upgrade pip setuptools

安装yotta：

pip install -U yotta

确保您拥有 Python 所需的所有构建工具。在 Windows 上，这通常意味着安装 Visual Studio 构建工具。

您可以使用以下方式安装它们：

pip install --upgrade setuptools wheel

但是，如果仍然存在问题，请尝试指定错误消息中所示的依赖项的确切版本。

祝你好运！
