记录一次python2.7.1 缺少**psutil**模块的解决过程

跑python脚本的时候报错ImportError: No module named psutil，于是想要用pip来安装。

但是发现pip也没装：

#  pip install psutil

-bash: pip: command not found

于是先安装pip：

wget “https://pypi.python.org/packages/source/p/pip/pip-1.5.4.tar.gz#md5=834b2904f92d46aaa333267fb1c922bb” --no-check-certificate

tar -xzvf pip-1.5.4.tar.gz
cd pip-1.5.4
python setup.py install

Traceback (most recent call last):

  File "setup.py", line 6, in 

    from setuptools import setup, find_packages

ImportError: No module named setuptools

发现setuptools也没有装，把setuptools也装上：

wget https://pypi.python.org/packages/source/s/setuptools/setuptools-0.6c11.tar.gz

tar zxvf setuptools-0.6c11.tar.gz

cd setuptools-0.6c11

python setup.py install

Installed /usr/lib/python2.6/site-packages/setuptools-0.6c11-py2.6.egg

Processing dependencies for setuptools==0.6c11

Finished processing dependencies for setuptools==0.6c11

安装完成后
再重新安装psutil：
pip install psutil

然而出现以下报错：
Command python setup.py egg_info failed with error code 1 in /tmp/pip_build_root/psutil

解决方式：

python -m pip install --upgrade --force pip

pip install setuptools==33.1.1

完成后重新安装又出现新的错误：
error: command ‘gcc’ failed with exit status 1

解决：

yum install gcc python-devel

再解决上面报错后，顺利安装

#pip install psutil

Successfully installed psutil

Cleaning up...
