无法在Windows上安装textract

Question

我尝试过很多东西，但是当我尝试使用pip命令在我的Windows上安装textract软件包时仍然失败。

我收到以下错误：

我不知道该怎么做，所以我真的很感激任何建议。 谢谢

Answer 1

从here被盗：

需要首先从conda（miniconda）安装swig

conda install swig

然后从发行版中下载EbookLib 0.15 zip

https://github.com/aerkalov/ebooklib/releases

解压缩后，我手动删除（我使用了notepad ++）README.md文件中的unicode char。 （unicode字符位于第44行）

然后使用pip安装该模块。

cd to_unzipped_folder_path_here
pip install .

最后

pip install textract

Answer 2

（Windows 10，Python 3.7） 我的问题比其他问题多，但这是基于先前的答案：

1. 确保已安装用于Python的Microsoft Visual Studio C ++编译器

   • 对于Visual Studio C ++ 14.0（Scrapy截至2019年6月的要求），       使用：https://wiki.python.org/moin/WindowsCompilers->
           https://visualstudio.microsoft.com/downloads/#build-tools-for-visual-studio-2017       -> https://visualstudio.microsoft.com/thank-you-downloading-visual-studio/?sku=Community&rel=16       注意：这可能需要很长时间才能安装，因此请耐心

2. python -m pip install --upgrade pip setuptools轮

3. pip安装六个--upgrade

4. 下载EbookLib 0.15版：

   • 解压缩.zip文件           为避免编码错误，请将变量“ long_description”分配为“ long_description =       open（'README.md'，encoding =“ utf-8”）。read（），“

5. 下载Swig：

   • http://www.swig.org/download.html
   • 解压缩.zip文件
   • 将swig.exe文件复制到Python路径中： “ C：\ Users \ username \ AppData \ Local \ Programs \ Python \ Python37”
   • 将“ typemaps”文件夹复制到python“ Lib”文件夹中： “ C：\ Program Files \ swigwin-4.0.0 \ Lib \ typemaps”->“ C：\ Users \ username \ AppData \ Local \ Programs \ Python \ Python37 \ Lib \”
   • 将“ * .swg”文件复制到python“ Lib”文件夹中： “ C：\ Program Files \ swigwin-4.0.0 \ Lib * .swg”->“ C：\ Users \ username \ AppData \ Local \ Programs \ Python \ Python37 \ Lib \”
   • 将所有swig python文件复制到python“ Lib”文件夹中： “ C：\ Program Files \ swigwin-4.0.0 \ Lib \ python *”->“ C：\ Users \ username \ AppData \ Local \ Programs \ Python \ Python37 \ Lib \”

6. cd从提示符进入解压缩的Ebooklib文件夹： C：> CD “ C：\ Users \ username \ Desktop \ ebooklib-0.15”

7. 运行EbookLib的安装：pip install。

8. 运行textract安装：pip install textract

输出应为：

在撰写本文时，jsonschema与textract的依赖项存在冲突。当我尝试找出正确的安装方式时，还会出现以下错误：

ERROR: requests 2.22.0 has requirement chardet<3.1.0,>=3.0.2, but you'll have chardet 2.3.0 which is incompatible.
ERROR: camelot-py 0.7.2 has requirement chardet>=3.0.4, but you'll have chardet 2.3.0 which is incompatible.

Answer 3

既然该项目似乎已由另一个人接管（最近写的答案是3个月前，当我撰写此答案时，最近又开始更新该项目），解决方案就更加简单了。

您现在可以转到https://github.com/deanmalmgren/textract/releases并下载v1.6.2，它仅提供v1.6.1上的要求更新（修复了unicode调试错误）或最新的v1.6.3（在撰写本文时）这个。）

下载后，解压缩cd [folder extracted to]和pip install .

请紧记，始终存在着这样的担忧，即随着需求的更新，恶意代码可能会插入到依赖项中，并自行承担风险。

这不是最优雅的解决方案，但它可以工作！

pip install git+https://github.com/jpweytjens/textract
