Question

Tôi đang sử dụng python 2.7 trên Windows. Làm thế nào đến lỗi sau xảy ra khi tôi cố cài đặt [lxml] [1] bằng cách sử dụng easy_install của [setuptools] [2]?

Answer 1

lxml> = 3.xx

1. tải về một trong những gói MS Windows Installer
2. easy_install "c:/lxml_installer.exe"(credit kobejohn)

MS Windows Installer downloads available for lxml 3.3.5

một list of all binary/egg lxml package downloads.

lxml 2.3.x

không có cửa sổ trứng nhị phân cho lxml 2.3.3 (2.3.0 là mới nhất từ ​​2.x.x).
mà không cần cung cấp số phiên bản easy_install sẽ tải xuống các nguồn mới nhất,
nhưng bạn chưa cài đặt libxml2 và libxslt.

bạn có thể cài đặt các libs thiếu hoặc bạn có thể thử 2.3 như có trứng nhị phân cho các cửa sổ:
easy_install lxml==2.3

Answer 2

bạn có thể tải không chính thức của Windows Binaries tại địa chỉ: http://www.lfd.uci.edu/~gohlke/pythonlibs/

ví dụ cho python 2.7 32bit: http://www.lfd.uci.edu/~gohlke/pythonlibs/#lxml

Đây là cách dễ nhất trong win32.

Answer 3

Tôi đã gặp phải sự cố tương tự. Tôi không biết về vấn đề vcvarsall.bat nhưng nếu bạn chỉ muốn cài đặt lxml bạn có thể sử dụng các trình cài đặt đồ họa ở đây:

https://pypi.python.org/pypi/lxml/3.2.3

Đó làm việc cho tôi.

Answer 4

Giải pháp lý tưởng (cũng hoạt động trong môi trường ảo) đã được cung cấp here.

Về cơ bản, nó xuống để tải xuống tệp bánh xe phù hợp từ here ("cp" trong tên tệp là viết tắt của phiên bản Python) và sau đó chỉ cần pip install nhập vào.

Nó hoạt động trên bản cài đặt Python3.3 (virtualenv) của tôi trên Windows 7 64 bit.

Answer 5

Bạn cũng có thể sử dụng anaconda. Một khi bạn đã cài đặt nó (http://continuum.io/downloads) bạn chỉ có thể chạy conda install lxml để cài đặt lxml.
