Question

我正在尝试使用Poetry在Windows笔记本电脑上安装RASA框架并从源代码构建。使用pip不会帮助我，因为我从未能够安装Tensorflow，而且RASA附带了它。

我已经做了什么：

$ curl -sSL https://raw.githubusercontent.com/python-poetry/poetry/master/get-poetry.py | python
$ git clone https://github.com/RasaHQ/rasa.git
$ cd rasa
$ poetry install

当安装到达要安装ujson的位置时，会发生这种情况，并且安装停止：

也许我可以简单地安装Anaconda并以这种方式完成它（tensorflow以这种方式工作），但是我想要构建的项目需要能够在任何给定时间在Anaconda之外运行。

有人可以帮我吗？顺便说一句，我已经安装了最新的Microsoft Visual C ++和构建工具。

Answer 1

尝试卸载当前版本的ujson

conda uninstall ujson

并尝试安装ujson-1.35

conda install ujson==1.35

Answer 2

窗口中可能有两个问题

如果在32位机器上安装而不是64位机器上出现位问题，请使用此 https://rasa.com/docs/rasa/user-guide/installation/#step-by-step-installation-guide
ujson兼容性问题，在这里讨论：https://github.com/ultrajson/ultrajson/issues/369

从https://www.lfd.uci.edu/~gohlke/pythonlibs/#ujson

下载您的whl文件

a）pip安装ujson-1.35-cp37-cp37m-win_amd64.whl

b）pip安装rasa

PYTHON ujson。错误：无法为使用PEP 517且无法直接安装的ujson构建轮子
