ImportError: Không có mô-đun tên là pandas

Question

Tôi đang cố gắng viết mã trong python để tìm nạp dữ liệu twitter tôi không nhận được lỗi cho twython. Nhưng tôi nhận được lỗi cho gấu trúc.

Tôi đã cài đặt gấu trúc bằng cách sử dụng gấu trúc cài đặt pip. Nhưng tôi vẫn nhận được lỗi này. Vui lòng giúp

Answer 1

Bạn đang thiếu một vài bước (không quá rõ ràng). Gấu trúc được phân phối thông qua pip như một wheel, có nghĩa là bạn cần làm:

pip install wheel 
pip install pandas 

Bạn có thể sẽ chạy vào các vấn đề khác sau này - có vẻ như bạn đang cài đặt trên Windows mà không phải là thân thiện nhất của các mục tiêu cho numpy/scipy/gấu trúc. Ngoài ra, bạn có thể lấy một trình cài đặt nhị phân từ here.

Bạn cũng gặp lỗi khi cài đặt gọn gàng. Giống như trước đây, tôi khuyên bạn nên grabbing a binary installer vì điều này, vì nó không phải là một quá trình đơn giản. Tuy nhiên, bạn có thể giải quyết lỗi hiện tại của mình theo số installing this package từ Microsoft.

Mặc dù hoàn toàn có thể thiết lập môi trường hoàn hảo trên Windows, nhưng tôi nhận thấy chất lượng cuộc sống cho một nhà phát triển Python được cải thiện đáng kể bằng cách thiết lập một máy ảo debian. Đặc biệt với các gói khoa học, bạn sẽ gặp phải nhiều trường hợp như thế này.

Answer 2

Khi tôi cố gắng xây dựng hình ảnh docker zeppelin-highcharts, tôi thấy rằng hình ảnh cơ bản openjdk: 8 cũng không có gấu trúc được cài đặt. Tôi đã giải quyết nó bằng các bước này.

curl --silent --show-error --retry 5 https://bootstrap.pypa.io/get-pip.py | python 
pip install pandas
