问题1：yum安装报错

No module named yum

解决：

前面安装了python2.7，默认2.6。python 版本更改后，

/usr/bin/yum 文件需要更新首行改为 #!/usr/bin/python2.6

问题2：pip command not found

[root@ Python-2.7.9]# pip install jinja2
-bash: pip: command not found

解决

[root@ ~]#  yum -y install python-setuptools
[root@ ~]#  easy_install pip

问题3：ImportError: No module named pkg_resources

[root@ ~]# easy_install pip

Traceback (most recent call last):

  File "/usr/bin/easy_install", line 5, in <module>

    from pkg_resources import load_entry_point

ImportError: No module named pkg_resources

解决：

[root@ ~]# curl https://bootstrap.pypa.io/ez_setup.py | python

问题4：easy_install pip 报错 The ‘distribute==0.6.10‘ distribution was not found

[root@ ~]# easy_install pip

Traceback (most recent call last):

  File "/usr/bin/easy_install", line 5, in <module>

    from pkg_resources import load_entry_point

  File "build/bdist.linux-x86_64/egg/pkg_resources/init.py", line 3019, in <module>

  File "build/bdist.linux-x86_64/egg/pkg_resources/init.py", line 3003, in _call_aside

  File "build/bdist.linux-x86_64/egg/pkg_resources/init.py", line 3032, in _initialize_master_working_set

  File "build/bdist.linux-x86_64/egg/pkg_resources/init.py", line 655, in _build_master

  File "build/bdist.linux-x86_64/egg/pkg_resources/init.py", line 963, in require

  File "build/bdist.linux-x86_64/egg/pkg_resources/init.py", line 849, in resolve

pkg_resources.DistributionNotFound: The ‘distribute==0.6.10‘ distribution was not found and is required by the application

解决：安装distribute

wget http://pypi.python.org/packages/source/d/distribute/distribute-0.6.10.tar.gz --no-check-certificate

tar zxvf distribute-0.6.10.tar.gz

cd distribute-0.6.10

python setup.py install

[root@ ~]# easy_install pip

成功

问题5：上图显示安装pip成功，但执行命令依然显示 command not found

[root@ ~]# pip install jinja2
-bash: pip: command not found

排查：

[root@ ~]# which pip
[root@~]# ls /usr/bin/pip

ls: 无法访问/usr/bin/pip: 没有那个文件或目录

解决：创建软连接：

[root@localhost ~]# ln -s /usr/bin/python2.7/bin/pip /usr/bin/pip

安装成功

[root@~]# pip install jinja2
