安装ruamel.yaml时面临的问题

Question

当我试图安装ruamel.yaml时，它会引发以下错误：

它以前起作用了。我正在使用docker，下面是在Dockerfile中使用的命令

RUN pip install ruamel.yaml
RUN pip install ruamel.yaml.jinja2

因为没有安装C编译器，所以会出现该错误。您可以做的一件事是确保安装了编译器，以便它能够编译ruamel.yaml.clib依赖项。

您正在安装ruamel.yaml车轮，我不明白为什么它没有为ruamel.yaml.clib安装车轮。这可能是由于体系结构或Python版本无法用于该体系结构造成的。

如果您的代码没有使用YAML(typ='safe')或其他实际使用C加载程序的内容，那么您也可以这样做：

RUN pip install --no-deps ruamel.yaml
