Mac OS X El Capitan - Scrapy/Python ImportError: nie można zaimportować nazwy xmlrpc_client

Question

Próbuję użyć Scrapy na Mac OS X El Capitan. Mam zainstalowany zsh i próbowałem wszystkiego, co mogłem znaleźć online, aby rozwiązać ten problem. Przyjrzałem się także Scrapy throws ImportError: cannot import name xmlrpc_client i nie mogłem rozwiązać mojego problemu! zainstalowany

Python poprzez brew i dodał "pip zainstalować scrapy":

➜ DriverEBV which python 
/usr/local/bin/python 

Moja .zshrc ma następującą linię:

export PATH=/usr/local/bin:$PATH 
export PYTHONPATH="/Library/Python/2.7/site-packages" 

Jest to błąd otrzymuję:

➜ DriverEBV scrapy runspider DriverEBV.py 
Traceback (most recent call last): 
    File "/usr/local/bin/scrapy", line 7, in <module> 
    from scrapy.cmdline import execute 
    File "/Library/Python/2.7/site-packages/scrapy/__init__.py", line 48, in <module> 
    from scrapy.spiders import Spider 
    File "/Library/Python/2.7/site-packages/scrapy/spiders/__init__.py", line 10, in <module> 
    from scrapy.http import Request 
    File "/Library/Python/2.7/site-packages/scrapy/http/__init__.py", line 12, in <module> 
    from scrapy.http.request.rpc import XmlRpcRequest 
    File "/Library/Python/2.7/site-packages/scrapy/http/request/rpc.py", line 7, in <module> 
    from six.moves import xmlrpc_client as xmlrpclib 
ImportError: cannot import name xmlrpc_client 

Po uruchomieniu "pip rem scrapy" teraz to widzę:

Ktoś może mi pomóc?

Answer 1

Co pomogło mi było deinstalacji sześć i scrapy a następnie zainstalować ponownie:

pip uninstall six 
pip uninstall scrapy 

pip install six 
pip install scrapy 

Uruchom z sudo w razie potrzeby.

Albo można też spróbować uaktualniania sześć i scrapy:

pip install --upgrade scrapy 
pip install --upgrade six 

Answer 2

miałem nic prócz bólu mucking z bibliotek Pythona systemu Mac OS X zainstalowany w katalogu /Library/Python. Co działa dobrze dla mnie jest kombinacją DarwinPorts i virtualenv:

1. Install MacPorts

2. zainstalować Python PIP i virtualenv z DarwinPorts: virtualenv

   /opt/local/bin/port install python27 
   /opt/local/bin/port install py27-pip 
   /opt/local/bin/port install py27-virtualenv 
   

3. konfiguracji:

   /opt/local/bin/virtualenv-2.7 myenv 
   

4. Aktywacja virtualenv (nie zapomnij kropki!)

   . myenv/bin/activate 
   

5. Install scrapy

   pip install scrapy 
   

ten sposób biblioteki systemu Python są nietknięte i można zainstalować pakiety cokolwiek chcesz bez konieczności usunięcia lub uaktualnienia istniejących pakietów.

Answer 3

Uważam, że najlepszym rozwiązaniem na OS X powinno być "Nie używaj systemowego pythona". Ułatwi to życie. This link pokazuje, jak to zrobić.

There’s a known issue that prevents pip from updating system packages. This has to be addressed to successfully install Scrapy and its dependencies. Here are some proposed solutions:

(Recommended) Don’t use system python, install a new, updated version that doesn’t conflict with the rest of your system. Here’s how to do it using the homebrew package manager:

1. Install homebrew following the instructions in http://brew.sh/
2. Update your PATH variable to state that homebrew packages should be used before system packages (Change .bashrc to .zshrc accordantly if you’re using zsh as default shell):

echo "export PATH=/usr/local/bin:/usr/local/sbin:$PATH" >> ~/.bashrc

3. Reload .bashrc to ensure the changes have taken place:

source ~/.bashrc

4. Install python:

brew install python

5. Latest versions of python have pip bundled with them so you won’t need to install it separately. If this is not the case, upgrade python:

brew update; brew upgrade python

Answer 4

Spróbuj odinstalować przez pip, a następnie ponownie zainstaluj, używając polecenia easy_install. Miałem ten sam problem z innym modułem Pythona i robiłem to w ten sposób naprawiłem problem na Mac OS X El Capitan.
