python3.6安装memory_profiler

1. 在centos中安装memory_profiler

pip3 install memory_profiler

报了个错：

    ----------------------------------------
Command "/usr/bin/python3 -u -c "import setuptools, tokenize;__file__=‘/tmp/pip-build-ctdkmofk/psutil/setup.py‘;f=getattr(tokenize, ‘open‘, open)(__file__);code=f.read().replace(‘\r\n‘, ‘\n‘);f.close();exec(compile(code, __file__, ‘exec‘))" install --record /tmp/pip-nuiv1vvh-record/install-record.txt --single-version-externally-managed --compile" failed with error code 1 in /tmp/pip-build-ctdkmofk/psutil/

解决方式：

sudo yum install python3-devel

2.重新安装memory_profiler

pip3 install memory_profiler

输出如下：
