Ubuntu14.04上安裝pip的方法

標籤：

在Ubuntu14.04上，通過sudo apt-get install python-pip下載的pip版本有些老，在使用時很可能出現下面的問題

[email protected]:~# pip Traceback (most recent call last):  File "/usr/bin/pip", line 9, in <module>    load_entry_point(‘pip==1.5.4‘, ‘console_scripts‘, ‘pip‘)()  File "/usr/lib/python2.7/dist-packages/pkg_resources.py", line 351, in load_entry_point    return get_distribution(dist).load_entry_point(group, name)  File "/usr/lib/python2.7/dist-packages/pkg_resources.py", line 2363, in load_entry_point    return ep.load()  File "/usr/lib/python2.7/dist-packages/pkg_resources.py", line 2088, in load    entry = __import__(self.module_name, globals(),globals(), [‘__name__‘])  File "/usr/lib/python2.7/dist-packages/pip/__init__.py", line 11, in <module>    from pip.vcs import git, mercurial, subversion, bazaar  # noqa  File "/usr/lib/python2.7/dist-packages/pip/vcs/mercurial.py", line 9, in <module>    from pip.download import path_to_url  File "/usr/lib/python2.7/dist-packages/pip/download.py", line 25, in <module>    from requests.compat import IncompleteReadImportError: cannot import name IncompleteRead

這是因為通過apt-get安裝的pip版本太老了，老的pip版本依賴requests.compat.IncompleteRead，而在2.4.0版本的requests中已經移除了

requests.compat.IncompleteRead，解決方案是先卸載pip（命令為sudo apt-get remove python-pip），然後通過下面的方式重新下載安裝

wget https://bootstrap.pypa.io/get-pip.py --no-check-certificatesudo python get-pip.py

安裝完後，測試一下吧，發現不能識別pip這個命令，額，我也不知道怎麼回事，解決辦法是在/usr/bin目錄下建一個軟肋接，指向到/usr/local/bin/pip

[email protected]:~$ pip-bash: /usr/bin/pip: No such file or directory        # $PATH的值包含/usr/bin[email protected]-test2:~$ which pip/usr/local/bin/pip                                    # $PATH的值包含/usr/local/bin[email protected]-test2:~$ [email protected]-test2:~$ echo $PATH/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games[email protected]-test2:~$
