PyCurl установлен, но не найден

Я пытаюсь установить pycurl в virtualenv с помощью easy_install, и он выглядит правильно установленным:

Однако при попытке использования я получаю следующую ошибку:

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

Любые предложения о том, как решить эту проблему, будут высоко оценены!

Распространение - Amazon Linux (EC2, 64 бит), Python - 2,7, установленный из источника. curl, libcurl и libcurl-dev все поставляются репозиториями Amazon yum и находятся в версии 7.19.7-26.20.

Я не могу установить пакет pycurl, предоставляемый репозиториями Amazon, потому что дистрибутив версии python равен 2.6, а мой проект работает на 2.7.

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

Ответ 1

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

При установке через pip -v install pycurl предоставляется 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)

Что показывает, что curl-config вызывается с аргументом --static-libs, который он не может распознать и вместо этого выводит его "использование". Самое главное, что он возвращает вывод кода без ошибок, который заставляет компилятор предположить, что компиляция pycurl.so прошла успешно.

Это описано более подробно здесь

Решение этой проблемы состояло в том, чтобы изменить pycurl setup.py и изменить строку 101, чтобы читать --libs вместо --static-libs. Это приводит к тому, что pycurl.so будет автоматически создан и скопирован в каталог site-packages.

Ответ 2

Обновление для 2015 года по этому вопросу.
Я столкнулся с этой установкой Pycurl на Mac, где работает Yosemite. Я изменил строку 150 в setup.py, как показано ниже:

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

for option in ["--libs"]:

Затем выполнил:

$>python setup.py install

После этого установка отлично работала!
