linux安装python27后pip: command not found报错

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 

    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

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
