我是靠谱客的博主专一蜜蜂，最近开发中收集的这篇文章主要介绍Linux离线安装fasttext库项目场景：问题描述：解决方案：，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

项目场景：

我想在不能联网的Linux服务器上部署 fasttext。

问题描述：

按照官方的步骤【传送门】，当时报错如下，这个错误就是联网连不上。
在这里插入图片描述

解决方案：

解决思路就是找到安装 fasttext 所需要的依赖，然后把依赖和fasttext一起复制到没有网的机器上。

所以你需要有一台可以联网且与服务器一样系统的电脑。

在有网的机器上使用pip install fasttext，你可以看到类似如下输出，证明你安装成功。可以看到 fasttext依赖两个库：pybind11 和 setuptools。

  DEPRECATION: A future pip version will change local packages to be built in-place without first copying to a temporary directoryend you use --use-feature=in-tree-build to test your packages with this new behavior before it becomes the default.
   pip 21.3 will remove support for this functionality. You can find discussion regarding this at https://github.com/pypa/pip/issu
