问题描述
当我在python中查看psutil的版本时,它说我有版本 0.5.0
:
when i check the version of psutil in python it says i have version 0.5.0
:
$ uname -a
Linux mypc 3.2.0-4-amd64 #1 SMP Debian 3.2.60-1+deb7u3 x86_64 GNU/Linux
$ python
Python 2.7.3 (default, Mar 13 2014, 11:03:55)
[GCC 4.7.2] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import psutil
>>> psutil.__version__
'0.5.0'
>>> psutil.virtual_memory()
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: 'module' object has no attribute 'virtual_memory'
>>> psutil.__file__
'/usr/lib/pymodules/python2.7/psutil/__init__.pyc'
我想升级到具有 virtual_memory()
方法的更新版本的psutil:
i want to upgrade to a newer version of psutil which has the virtual_memory()
method:
$ sudo pip install 'psutil==2.2.1' --upgrade
Requirement already up-to-date: psutil==2.2.1 in /usr/local/lib/python2.7/dist-packages
Cleaning up...
相同的包意味着 psutil
已安装两次:
the two different paths for the same package imply that psutil
is installed twice:
/usr/local/lib/python2.7/dist-packages
/usr/lib/pymodules/python2.7/psutil/__init__.pyc
我只想要 psutil
版本 2.2.1
。清理其他不需要的 0.5.0
包的最佳方式是什么?只需稍后再保留一下?
i only want psutil
version 2.2.1
. what is the best way to clean up the other unwanted 0.5.0
package and only keep this later one?
根据评论 - 检查以上任一路径是否通过 dpkg
安装:
as per the comments - checking if either of the above paths were installed through dpkg
:
$ dpkg -S /usr/local/lib/python2.7/dist-packages
dpkg-query: no path found matching pattern /usr/local/lib/python2.7/dist-packages
$ dpkg -S /usr/lib/pymodules/python2.7/psutil/__init__.pyc
dpkg-query: no path found matching pattern /usr/lib/pymodules/python2.7/psutil/__init__.pyc
推荐答案
p>删除所有版本的 psutil
并再次安装 2.2.1
remove all versions of psutil
and install 2.2.1
again:
$ sudo pip uninstall psutil
Uninstalling psutil:
/usr/local/lib/python2.7/dist-packages/_psutil_linux.so
/usr/local/lib/python2.7/dist-packages/_psutil_posix.so
/usr/local/lib/python2.7/dist-packages/psutil
/usr/local/lib/python2.7/dist-packages/psutil-2.2.1.egg-info
