我在 Pycharm 中成功安装了 Python 包 spaCy。我可以通过python -m spacy validate（我使用的是 macOS）在 Pycharm 和终端中看到它已安装。任何人都可以帮助我理解以下错误吗？我真的迷路了。我要做的就是导入包，仅此而已。我唯一的代码是import spacy。错误如下所示：

标签： python python-3.x package spacy

【解决方案1】：

这是 python 2.7 和 spacy v2.2.4 或 v2.3.0--2.3.2 的错误。它应该在 v2.3.3+ 中修复。

除非你有特殊的原因要使用 python 2.7，否则最好切换到 python 3.6+。
