执行“pip install r”时出现以下错误要求.txt“命令

Question

我是一个初学者，正在使用RASA框架开发聊天机器人项目。当我尝试使用“pip install RASA”命令或内部依赖项安装RASA时要求.txt[snap attached]使用“pip install-r要求.txt“，我正在低于错误。 为了解决这个问题，我在中更改了关注依赖项版本要求.txt但即使这样也帮不了我。在

例如，在下面的例子中，每个日志的要求是“fbmessenger~=6.0”，而不是5.0.0版（现有的）。在

错误：rasa 1.3.9要求fbmessenger~=6.0，但您将使用不兼容的fbmessenger 5.0.0。在

如果我在中将版本5.0更改为6.0要求.txt然后它将再次抛出错误，现在要求5.0版本。像

错误：rasa 1.2要求fbmessenger ~=5.0，但您将使用不兼容的fbmessenger 6.0.0。

Answer 1

我觉得您正在尝试在一个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，然后启动下面的命令，一切正常。在

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

以前肯定有人安装了rasa-x。早期版本有不同版本的依赖项，在这两者之间，rasa-x与其依赖版本一起得到了升级。现在，当您试图重新安装它时，您将面临冲突。在

如果您有一个特定版本的rasa-x，比如0.21.4，那么您可以将其安装到新的venv中，如下所示：

我刚把版本号加到包名后面。在

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包的最新版本，而不是拥有所有文档。在

不过，这些软件包中的大部分都是rasa附带的。您只需安装： pip安装rasa

如果你有一些库而不是rasa附带的库，只需使用“pip install（package_name）”安装它们
