PyCurl cài đặt nhưng không tìm thấy

Question

Tôi đã cố gắng để cài đặt pycurl trong một virtualenv với easy_install, và nó xuất hiện để cài đặt một cách chính xác:

(xxx) $ easy_install pycurl

Tuy nhiên, khi cố gắng sử dụng, tôi nhận được lỗi sau:

Mặc dù thực tế tôi có thể thấy rõ ràng pycurl-7.19.0-py2.7-linux-x86_64.egg trong thư mục ~/.virtualenvs/xxx/lib/python2.7/site-packages của tôi.

Bất kỳ đề xuất nào về cách giải quyết vấn đề này sẽ được nhiều người đánh giá cao!

Phân phối là Amazon Linux (EC2, 64 bit), Python là 2,7, được cài đặt từ nguồn. curl, libcurl và libcurl-dev đều được cung cấp bởi Amazon yum repos và có phiên bản 7.19.7-26.20.

Tôi không thể cài đặt gói pycurl do Amazon cung cấp vì phiên bản python cung cấp phân phối là 2.6 và dự án của tôi chạy trên 2.7.

Nó không phải là một vấn đề con đường, các nội dung của sys.path là như sau:

>>> import sys; sys.path

tôi đã được quản lý (với sự giúp đỡ) để giải quyết vấn đề. Vấn đề là sau khi cài đặt, pycurl.so không được sao chép vào các gói trang web cho virtualenv này.

Khi cài đặt qua pip -v install pycurl, đầu ra sau đây được đưa ra:

Các lỗi chủ chốt ở đây là: gcc -pthread -shared build/temp.linux-x86_64-2.7/src/pycurl.o -L/opt/python2.7/lib -lcurl -lpython2.7 -o build/lib.linux-x86_64-2.7/pycurl.so unknown option: --static-libs Usage: curl-config [OPTION] Available values for OPTION include: --ca ca bundle install path --cc compiler --cflags pre-processor and compiler flags --checkfor [version] check for (lib)curl of the specified version --features newline separated list of enabled features --help display this help and exit --libs library linking information --prefix curl install prefix --protocols newline separated list of enabled protocols --version output version information --vernum output the version information as a number (hexadecimal)

nào cho thấy curl-config đang được gọi với đối số --static-libs, mà nó không nhận ra và thay vào đó in ra đầu ra 'sử dụng' của nó. Quan trọng nhất, nó trả về một đầu ra không mã lỗi mà làm cho trình biên dịch giả định biên dịch pycurl.so đã thành công.

này được mô tả chi tiết here

Các giải pháp cho vấn đề này đã được sửa đổi của pycurl setup.py và thay đổi dòng 101 để đọc --libs thay vì --static-libs. Điều này làm cho pycurl.so được xây dựng và sao chép vào thư mục site-packages thành công.

Answer 2

Bản cập nhật cho năm 2015 về vấn đề này.
Tôi đã chạy cài đặt Pycurl này trên máy Mac chạy Yosemite. Tôi đã thay đổi dòng trong setup.py như hình dưới đây:

for option in ["--libs", "--static-libs"]: 

tới:

for option in ["--libs"]: 

Sau đó chạy:

$>python setup.py install 

Installation làm việc hoàn hảo sau này!
