[英]Errors and Warnings when installing Scrapy with pip on OSX
我想在Macbook OSX 10.9上安裝Scrapy
我遵循了此處列出的所有先決條件: http : //doc.scrapy.org/en/latest/intro/install.html
然后在終端中輸入以下內容: pip install Scrapy
在終端的最底部說:
2 warnings and 6 errors generated.
error: command '/usr/bin/clang' failed with exit status 1
然后在其下方顯示:
----------------------------------------
Cleaning up...

我去看了一下,在Macbook上現在有一個名為“ Scrapy”的文件夾,它包含一個名為“ scrapy-scrapy-0.22.0-7-gcde9a8c.zip”的zip文件,但是就是這樣,所以我假設它是沒有成功安裝?
還是應該忽略錯誤和警告並解壓縮zip文件?
謝謝您的幫助。
編輯:我知道一個事實,它沒有安裝,因為當我嘗試啟動一個新的scrapy項目時終端會給我這個輸出:
Traceback (most recent call last):
File "/Library/Frameworks/Python.framework/Versions/3.3/bin/scrapy", line 3, in <module>
from scrapy.cmdline import execute
File "/Library/Frameworks/Python.framework/Versions/3.3/lib/python3.3/site-packages/scrapy/__init__.py", line 43, in <module>
from twisted import version as _txv
ImportError: No module named 'twisted'
編輯2-這是打印的6個錯誤:
^ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

不幸的是,Scrapy還不支持Python 3-由於扭曲的問題,移植尚未開始。 Scrapy 0.22僅適用於Python 2.7。
要成功安裝Scrapy,您需要確保已經安裝了Twisted工具。
當我嘗試在Mac中安裝Scrapy和Twisted時,遇到了同樣的問題,“錯誤:命令'/ usr / bin / clang'失敗,退出狀態為1”。
安裝Xcode后,此問題已解決。 我不確定您是否使用像我這樣的MacOS系統。 如果是,這可能對您有幫助。
命令行:
xcode-select --install
