使用python 3.3的請求

Question

如何安裝與python 3.3一起使用的請求 。

我使用mac，並安裝了python 3.3和2.7.1。 路徑。

2.7.1 : 

which python
/usr/bin/python

3.3:
/Library/Frameworks/Python.framework/Versions/3.3/bin

我試過這些安裝

curl -O http://python-distribute.org/distribute_setup.py
sudo /Library/Frameworks/Python.framework/Versions/3.3/bin/python3 distribute_setup.py
sudo /Library/Frameworks/Python.framework/Versions/3.3/bin/python3 -m easy_install pip
sudo /Library/Frameworks/Python.framework/Versions/3.3/bin/pip install requests

最后一步給出錯誤：

 File "./requests/utils.py", line 22, in <module>

    from .compat import parse_http_list as _parse_list_header

  File "./requests/compat.py", line 112, in <module>

    from .packages import chardet2 as chardet

ImportError: cannot import name chardet2

我嘗試將PYTHONPATH設置為：

echo $PYTHONPATH
/Library/Frameworks/Python.framework/Versions/3.3/lib/python3.3/site-packages
[~/tmp] $ 

還是一樣的錯誤。

安裝chardet2之后我也試過了; 但

   $ python3.3
Python 3.3.0 (v3.3.0:bd8afb90ebf2, Sep 29 2012, 01:25:11) 
[GCC 4.2.1 (Apple Inc. build 5666) (dot 3)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import chardet2

  File "<stdin>", line 1, in <module>

Answer 1

奶酪店頁面當前顯示版本0.14.2的“構建狀態失敗”。 看起來像下載這個tarball並嘗試構建/測試/安裝它確實失敗了3.3。 這並不太令人驚訝，因為0.14.1是第一個使用3.3版本的版本，可能沒有多少人在3.3版本中使用它...

那么，您可以做些什么（除了以適當的方式報告錯誤）？ 兩種選擇：

• 獲取0.14.1 tarball並安裝它。
• 獲取最新的源代碼並安裝它。

第二個實際上更容易，並且可能更好（當它工作時），並且它實際上在Requests 的文檔中建議。

但是，文檔沒有告訴您的是，在使用最新源時，您可以獲得pip的優點和簡單性：

pip-3.3 install git+https://github.com/kennethreitz/requests

我剛剛對此進行了測試，並且工作正常，並且（正如預期的那樣）給出了與請求文檔中的說明完全相同的結果。
