在anaconda提示符下使用此命令，然后重试安装rasa。我想这会解决你的问题

while trying to install rasa nlu i am getting following error:

我为类似问题找到的工作解决方案

转到错误中提到的，下载最新版本的安装程序，运行安装程序

如果已安装visual studio，请单击“修改”， 确保选择所需的软件包，特别是“windows 10 sdk”，如[首次安装需要大约1.2gb的下载和4.2gb的磁盘空间]

然后运行

pip install rasa\u nlu

，以成功构建包

如果系统中安装了Anaconda发行版，则可以尝试运行

conda install -c conda-forge httptools

然后尝试运行pip命令

---

<> p>但是对于所有的Windows Python版本组合都不起作用。任何时候，构建这些包都需要VisualC++。< /P>它告诉你库已经编译了代码，但是你没有编译器。最简单的解决方案可能是

conda安装-c conda forge httptools

@cel谢谢你，它成功了，经过一周的努力我终于安装了rasa，你是我的救世主你还没有指定你使用的是哪个windows操作系统版本。但这个错误是不言自明的。您需要安装Microsoft VC++构建工具14.0版本。

conda install -c conda-forge httptools
