#安裝python2.7版本

tar xvf Python-2.7.9.tar.xz

cd Python-2.7.9

./configure --prefix=/usr/bin/python2.7

make

make install

mv /usr/bin/python /usr/bin/python.bak

ln -s /usr/bin/python2.7/bin/python2.7 /usr/bin/python

問題1：yum安裝報錯

No module named yum

解決：

前面安裝了python2.7，默認2.6。python 版本更改後，

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

問題2：pip command not found

[root@ Python-2.7.9]# pip install jinja2

-bash: pip: command not found

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

[root@ ~]# easy_install pip

問題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

解決：

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

問題4：easy_install pip 報錯 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>

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

解決：安裝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

問題5：上圖顯示安裝pip成功，但執行命令依然顯示 command not found

[root@ ~]# pip install jinja2

-bash: pip: command not found

排查：

[root@ ~]# which pip

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

ls: 無法訪問/usr/bin/pip: 沒有那個文件或目錄

解決：創建軟連接：

[[email protected] ~]# ln -s /usr/bin/python2.7/bin/pip /usr/bin/pip

安裝成功

[root@~]# pip install jinja2
