ImportError: No module named psutil的解決

系統版本：

cat /etc/redhat-release

CentOS release 6.9 (Final)

 

跑python腳本的時候報錯ImportError: No module named psutil，因而想要用pip來安裝，可是發現pip也沒裝：

#  pip install psutil

-bash: pip: command not found

 

先來安裝pip吧：

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 <module>

    from setuptools import setup, find_packages

ImportError: No module named setuptools

 

 

而後發現setuptools也沒有裝，因而把setuptools也裝上吧：

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

出現以上提示表明setuptools成功安裝

 

安裝好setuptools後，又繼續裝pip:

cd pip-1.5.4

python setup.py install

出現如下提示表示pip安裝完成：

Installed /usr/lib/python2.6/site-packages/pip-1.5.4-py2.6.egg

Processing dependencies for pip==1.5.4

Finished processing dependencies for pip==1.5.4

 

Pip裝好後，就能夠安裝psutil了，可是安裝過程當中以遇到了一些問題：

# pip install psutil

報錯：

Traceback (most recent call last):

  File "/usr/bin/pip", line 8, in <module>

    load_entry_point('pip==1.5.4', 'console_scripts', 'pip')()

  File "/usr/lib/python2.6/site-packages/pip-1.5.4-py2.6.egg/pip/__init__.py", line 185, in main

    return command.main(cmd_args)

  File "/usr/lib/python2.6/site-packages/pip-1.5.4-py2.6.egg/pip/basecommand.py", line 161, in main

    text = '\n'.join(complete_log)

UnicodeDecodeError: 'ascii' codec can't decode byte 0xe2 in position 48: ordinal not in range(128)

 

解決方法：

vim /usr/lib/python2.6/site-packages/pip-1.5.4-py2.6.egg/pip/basecommand.py

在import sys 後面加下面兩行：

reload(sys)

sys.setdefaultencoding('utf8')

 

報錯2：error: command 'gcc' failed with exit status 1

yum install gcc python-devel

 

再解決上面報錯後，就能順利安裝了

pip install psutil

Successfully installed psutil
