python 安装psutil

Posted 2020-12-28 aity007

在使用python组件psutil时需要先安装，具体如下：

 

    wget https://pypi.python.org/packages/source/p/psutil/psutil-2.0.0.tar.gz
    tar -xzvf psutil-2.0.0.tar.gz
    cd psutil-2.0.0
    python setup.py install

安装的过程中可能报错如下：

psutil/_psutil_linux.c:421: error: expected specifier-qualifier-list before ?.yObject?
psutil/_psutil_linux.c: In function ?.nit_psutil_linux?.
psutil/_psutil_linux.c:470: error: ?.yObject?.undeclared (first use in this function)
psutil/_psutil_linux.c:470: error: (Each undeclared identifier is reported only once
psutil/_psutil_linux.c:470: error: for each function it appears in.)
psutil/_psutil_linux.c:470: error: ?.odule?.undeclared (first use in this function)
psutil/_psutil_linux.c:470: warning: implicit declaration of function ?.y_InitModule?
psutil/_psutil_linux.c:470: error: ?.sutilMethods?.undeclared (first use in this function)
error: command ‘gcc‘ failed with exit status 1

报错原因为没有安装python-devel导致，直接yum安装即可。
