即使安装了psutil，也没有此类模块psutil [英] No such module psutil, even though psutil is installed

问题描述

我在OS X El Capitan上.

I am on OS X El Capitan.

我想为python脚本导入psutil，但得到module psutil not found.

I want to import psutil for a python script, but get module psutil not found.

如果执行pip install psutil，我已经安装了psutil.

If I do pip install psutil I get psutil already installed.

我怎么可能安装了psutil，但是在脚本中找不到它?

How is this possible that I have psutil installed, but it does not find it in the script?

我同时使用macports和Homebrew来安装几个python软件包.也许这是一个问题?

I am using both macports and homebrew to install several python packages. Maybe this is a problem?

有什么想法可以使psutil导入吗?

Any ideas how I can get psutil to import?

我的系统上有python27和python34.对于这个项目，我需要使用python27.

I have python27 and python34 on my system. For this project I need to use python27.

这是我的pip freeze

推荐答案

只是尝试一览一下，这也是一种需要psutil的诊断工具.不幸出现错误:

Just tried to run glances, some kind of diagnostic tool that requires psutil aswell. Unfortunatelly got an error :

PsUtil module not found. Glances cannot start.

Ran pip冻结，看到我已安装它，因此我决定删除并尝试重新安装.卸载(成功卸载了psutil-5.0.1)，并且再次尝试安装psutil-5.0.1时失败.再次点冻结，并发现有一个次要版本(psutil == 2.2.1)，以防您删除最新版本(非常奇怪). 无论如何，再次运行pip卸载psutil，删除该次要版本，然后当我再次尝试重新安装时，可以正常工作，安装最后一个版本.

Ran pip freeze, saw that i had it installed and i decided to remove and try to reinstall. Uninstalled (Successfully uninstalled psutil-5.0.1) and when tried again to install psutil-5.0.1 failed. Ran again pip freeze and noticed there is a minor version (psutil==2.2.1) that is served in case you remove the latest (very strange). Anyway, run again pip uninstall psutil, removed that minor version and when i tried again to reinstall worked correctly, installing the last version.

现在一切正常.
