我在我的 RPi 上安装了 psutil，sudo apt-get install python-psutil但它给了我 v0.5.1
我想使用 v2.1.1，因为它有 v0.5.1 没有的 virtual_memory() 命令。
尝试从 PIP 升级 psutil 时，sudo pip install --upgrade psutil它开始安装然后退出并出现以下错误：
pi@raspbmc:~$ sudo pip install --upgrade psutil

sudo apt-get remove --purge python-psutil我尝试使用then卸载 python-psutilsudo pip install psutil但返回相同的错误。同样的故事sudo easy_install psutil
接下来，我试图确保我已经安装python-dev并libevent-dev安装了。python-dev已经安装和更新但libevent-dev没有。所以我更新了它并sudo pip install psutil再次尝试无济于事（同样的错误）。
我错过了什么吗？
