【发布时间】：2022-09-27 14:32:52
【问题描述】：

!pip install cython 
!pip install cymem
!pip install murmurhash
!pip install preshed
!pip install numpy
!pip install blis
!pip install thinc
!pip install \'spacy[apple]\'
!pip install -U pip setuptools wheel

以上所有代码都有效。

但是当我尝试运行下面的代码时

!python -m spacy download en_core_web_sm

我收到以下错误，因此无法导入 spacy ：

【解决方案1】：

在一个新的 venv 中，试试这个：

pip install -U pip setuptools wheel
pip install 'spacy[apple]' --only-binary spacy,thinc,blis,thinc-apple-ops --no-cache-dir

如果这可行，您可能需要清除您的 pip 缓存以删除过去可能从源代码编译的不兼容缓存轮 (pip cache purge)，然后一个简单的pip install 'spacy[apple]' 应该再次工作。（无需单独安装其他依赖项。）
