我的 Ubuntu 10.04 带有 Python 2.6。现在，我还安装了 Python 2.7，这是系统默认的，因为当我python从终端启动时，它会启动 python 2.7。

现在，我想使用 pip 安装库 pysftp，但我很难这样做。以下是我的尝试和结论的一些结果。我做了pip install pysftp，但它说以下内容：

Downloading/unpacking pysftp
  Running setup.py egg_info for package pysftp
    Traceback (most recent call last):
      File "<string>", line 3, in <module>
      File "/usr/local/lib/python2.6/dist-packages/setuptools/__init__.py", line 12, in <module>
        from setuptools.extension import Extension
      File "/usr/local/lib/python2.6/dist-packages/setuptools/extension.py", line 8, in <module>
        from .dist import _get_unpatched
      File "/usr/local/lib/python2.6/dist-packages/setuptools/dist.py", line 21, in <module>
        packaging = pkg_resources.packaging
    AttributeError: 'module' object has no attribute 'packaging'
    Complete output from command python setup.py egg_info:
    Traceback (most recent call last):

  File "<string>", line 3, in <module>

  File "/usr/local/lib/python2.6/dist-packages/setuptools/__init__.py", line 12, in <module>

    from setuptools.extension import Extension

  File "/usr/local/lib/python2.6/dist-packages/setuptools/extension.py", line 8, in <module>

    from .dist import _get_unpatched

  File "/usr/local/lib/python2.6/dist-packages/setuptools/dist.py", line 21, in <module>

    packaging = pkg_resources.packaging

AttributeError: 'module' object has no attribute 'packaging'

----------------------------------------
Command python setup.py egg_info failed with error code 1

在我看来，pip（显然是在安装 Python 2.7 之前安装的）链接到不支持 pysftp 的旧版 Python。也因为当我这样做pip --version时说：

pip 0.3.1 from /usr/lib/python2.6/dist-packages (python 2.6)

当我这样做时whereis python，它会给我以下信息：

python: /usr/src/Python-2.7.10/python /usr/bin/python2.6 /usr/bin/python /etc/python2.6 /etc/python /usr/lib/python2.6 /usr/lib/python3.1 /usr/lib64/python2.6 /usr/lib64/python3.1 /usr/local/bin/python2.7-config /usr/local/bin/python /usr/local/bin/python2.7 /usr/local/lib/python2.6 /usr/local/lib/python2.7 /usr/include/python2.6 /usr/share/python /usr/share/man/man1/python.1.gz

如何安装 pysftp？

您需要重新安装pipPython 2.7，然后运行pip2.7 install pysftp​​. 您需要pip为要使用的每个 Python 版本进行安装。setuptools打包可能是最简单的方法。您可以简单地运行以下命令一举完成所有操作：

wget https://bootstrap.pypa.io/ez_setup.py -O --no-check-certificate - | sudo python2.7 && sudo easy_install-2.7 pip && sudo pip2.7 install pysftp

setuptools有时较旧的 Linux 安装会出现上述命令的问题，因为在通过下载完整包时遇到“无效”证书ez_setup.py（有关更多详细信息，请参见此处）。这可以通过这个替代的 one-fell-swoop 命令来规避：

wget https://pypi.python.org/packages/source/s/setuptools/setuptools-18.8.1.zip --no-check-certificate && unzip setuptools-18.8.1.zip && cd setuptools-18.8.1 && sudo python setup.py install && sudo easy_install-2.7 pip && sudo pip2.7 install pysftp

我认为您需要使用代码安装某种“基本包”

sudo apt-get install build-essential libssl-dev libffi-dev python-dev

然后你可以安装：

sudo pip install pysftp
sudo pip install enum
