从 GitHub 安装 Python 库完成 4 种方法（未成功）

Question

我必须安装一个名为 sonLib from the author's Git repo. It is a dependency of jobTree, which I will also later need. Trouble is it won't install. I've tried 4 methods listed below. Methods 1) and 3) both have the same error which is addressed here, but I could not find an analgous error in his setup.py 的 python package/library/module。这些错误中是否存在最容易处理的错误之一？是否有另一种方法来安装这个（和 jobTree），以便我可以通过位于 /usr/bin/python2.7 中的 python 导入它？

方法一

git clone https://github.com/benedictpaten/sonLib.git
cd /sonLib
sudo python2.7 setup.py install

错误：

running install
running bdist_egg
running egg_info

writing dependency_links to sonLib.egg-info/dependency_links.txt

writing dependency_links to sonLib.egg-info/dependency_links.txt
writing manifest file 'sonLib.egg-info/SOURCES.txt'
error: package directory 'sonLib' does not exist

方法二

sudo pip install -e git://github.com/benedictpaten/sonLib.git

错误：

方法三

sudo pip install git+https://github.com/benedictpaten/sonLib.git

错误：

方法四

来自相关的 sonLib 安装 post on SO。

cd /usr/local/lib/python2.7/site-packages/sonLib
sudo git clone https://github.com/benedictpaten/sonLib.git
sudo make all
make test

错误：

Answer 1

您使用的 pip-install-command-syntax 可能有误，在 https://pip.pypa.io/en/latest/reference/pip_install.html#git 之后应该是：

pip install -e git+https://github.com/benedictpaten/sonLib.git#egg=sonLib

"No module named 'pip'" 告诉您当前 Python-解释器没有可用的 pip。如您的示例所示，您正在使用多个 Python 版本。您使用 Python-2.7 安装了 sonLib，然后尝试使用 Python-3.3 的 pip。对于防弹方式，使用 Python-2.7 的 virtenv 并执行：

$ virtenv yourVirtualEnv
$ cd yourVirtualEnv
$ . bin/activate

virtenv 将一路安装 pip，激活它可确保您在几乎不输入 pip 的情况下就可以在命令行中使用它的 pip。完成后，再次停用virtualenv，就是：

$ deactivate

无论如何，激活不是永久性的，当您的 shell-session 结束时，它也会消失。或者将路径添加到您的 .bashrc，如果您希望它永久成为您的默认 pip。
