无法在使用pip3中安装snips-nlu-en？

Question

我正在尝试安装snips-nlu-en，但一直收到以下错误：

sudo -H pip3 install snips-nlu-en

Exception:

requests.exceptions.HTTPError: 404 Client Error: Not Found for url: https://pypi.org/simple/snips-nlu-en/

请告诉我怎样才能修复它？

Answer 1

没有这样的包：https://pypi.org/project/snips-nlu-en/返回错误404。您尝试安装的是什么？

这里有snips-nlu，这是你想要的吗？

pip install snips-nlu

Answer 2

snips-nlu-en是snips-nlu在您运行以下命令时安装的resource package：

python -m snips_nlu download en

这个资源包是hosted on github的，而不是在pip install上的，这就是为什么你不能直接通过pypi安装它。

获取最新snips-nlu-en版本的最好方法是首先使用pip install --upgrade snips-nlu更新snips-nlu，然后使用前面提到的命令下载资源。
