Si alguien pudiera ayudarme, ¡realmente lo apreciaría! Tengo la sospecha de que el problema tiene que ver con varias versiones de Python, pero no estoy seguro de cómo comprobarlo o corregirlo.

Edición 1: cuando intento sudo pip install lxml :

Answer 1

Configurar un virtualenv :

% curl -kLso /tmp/get-pip.py https://bootstrap.pypa.io/get-pip.py
% sudo python /tmp/get-pip.py

Estos comandos instalan pip en el directorio global de paquetes de sitio.

% sudo pip install virtualenv

y lo mismo para virtualenv:

% mkdir -p ~/.virtualenvs

Me gustan mis virtualenvs bajo un árbol en mi directorio personal llamado .virtualenvs

% virtualenv ~/.virtualenvs/lxmltest

Crea un virtualenv.

% . ~/.virtualenvs/lxmltest/bin/activate

Elimina la necesidad de especificar la ruta completa a pip / python en este virtualenv.

% pip install lxml

Alternativamente, ejecute ~/.virtualenvs/lxmltest/bin/pip install lxml si elige no seguir el paso anterior. Tenga en cuenta que no estoy seguro de qué tan avanzado está, por lo que algunos de estos pasos se pueden omitir de manera segura. Por supuesto, si estropea algo, siempre puede rm -Rf ~/.virtualenvs/lxmltest y comenzar de nuevo desde un nuevo virtualenv.

Answer 2

En una Mac, necesitas usar este comando:

STATIC_DEPS = verdadero sudo pip install lxml

Answer 3

Parece que tiene un error de permisos, basado en este mensaje en su salida: error: could not create ''/lib/python2.7/site-packages/lxml'': Permission denied .

Una cosa que puedes probar es hacer una instalación de usuario del paquete con pip install lxml --user . Para obtener más información sobre cómo funciona, consulte esta respuesta de . (Gracias a Ishaan Taylor por la sugerencia)

También puedes ejecutar pip install como superusuario con sudo pip install lxml pero generalmente no es una buena idea porque puede causar problemas con tus paquetes a nivel de sistema.
