PyCurl установлен, но не найден

Я пытался установить pycurl в virtualenv с помощью easy_install, и, похоже, он устанавливается правильно:

Однако при попытке использовать я получаю следующую ошибку:

Несмотря на то, что я ясно вижу pycurl-7.19.0-py2.7-linux-x86_64.egg в моем ~/.virtualenvs/xxx/lib/python2.7/site-packages каталоге.

Мы будем очень благодарны за любые предложения о том, как решить эту проблему!

Распространяется Amazon Linux (EC2, 64 бит), Python 2.7, устанавливается из исходников. curl, libcurl и libcurl-dev поставляются в репозиториях Amazon yum и имеют версию 7.19.7-26.20.

Я не могу установить пакет pycurl, предоставленный репозиториями Amazon, потому что версия python, поставляемая дистрибутивом, - 2.6, а мой проект работает на 2.7.

Это не проблема пути, содержимое sys.path выглядит следующим образом:

что вы получаете от sys.path?   -  person Tommaso Barbugli    schedule 12.09.2011

Томассо: добавлен вывод sys.path к основному вопросу, так как поле комментариев слишком короткое. Это не вопрос пути. Есть другие предложения?   -  person majackson    schedule 13.09.2011

Мне удалось (с некоторой помощью) решить проблему. Проблема в том, что после установки pycurl.so не копируется в пакеты сайтов для этого virtualenv.

При установке через pip -v install pycurl выдается следующий вывод:

Ключевая ошибка здесь: 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)

Это показывает, что curl-config вызывается с аргументом --static-libs, который он не может распознать и вместо этого печатает вывод «использования». Что наиболее важно, он возвращает вывод без кода ошибки, который заставляет компилятор предполагать, что компиляция pycurl.so прошла успешно.

Более подробно это описано здесь.

Решением этой проблемы было изменение файла setup.py pycurl и изменение строки 101 на --libs вместо --static-libs. Это приводит к успешному построению pycurl.so и его копированию в каталог site-packages.

Это просто спасло мне день. Сходили с ума, пытаясь установить его в моем virtualenv. Спасибо! - person Praveen Gollakota; 04.04.2012

Обновление за 2015 год по этой проблеме.
Я столкнулся с этой установкой Pycurl на Mac, работающем под управлением Yosemite. Я изменил строку 150 в setup.py, как показано ниже:

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

to:

for option in ["--libs"]:

Потом побежал:

$>python setup.py install 

После этого установка прошла отлично!
