Question

我是一个初学者，正在使用RASA框架从事Chatbot项目。当我尝试使用“ pip install -r requirements.txt”使用“ pip install rasa”命令或require.txt [附加的快照]内的依赖项安装RASA时，出现以下错误。为了解决该问题，我在Requirement.txt中更改了关注依赖项版本，但即使这样也无济于事。

例如，在以下情况下，每个日志要求使用“ fbmessenger〜= 6.0”代替版本5.0.0（现有版本）。

错误：rasa 1.3.9要求fbmessenger〜= 6.0，但您将拥有不兼容的fbmessenger 5.0.0 。

如果我将require.txt文件中的版本5.0更改为6.0并运行命令，则它将再次引发错误，现在要求版本为5.0。喜欢

错误：rasa 1.2要求fbmessenger〜= 5.0，但您将拥有不兼容的fbmessenger 6.0.0。

Answer 1

当您尝试安装与新版本不兼容的旧版本时，会发生这种情况。我建议您可以手动安装这些软件包的最新版本，而不是拥有所有文档。

但是这些软件包大多数都随rasa一起提供。您可以通过以下方式安装它们： pip安装rasa

如果除了rasa附带的那些库以外，还有其他库，请使用“ pip install（package_name）”安装它们。

我觉得您正在尝试在已经存在的虚拟环境（venv）中安装rasa-x。请创建一个新的venv文件夹，然后执行以下命令，一切正常。

 pip install rasa-x --extra-index-url https://pypi.rasa.com/simple

以前必须有人安装了rasa-x。较早的版本具有不同版本的依赖关系，并且在rasa-x与依赖版本之间进行了升级。现在，当您尝试重新安装它时，您会遇到冲突。

如果您有特定版本的rasa-x，例如0.21.4，则可以按如下所示将其安装在新的venv中：

pip install rasa-x==0.21.4 --extra-index-url https://pypi.rasa.com/simple

我刚刚将版本号附加到了程序包名称上。
