【linux】centos7 & ubuntu20.04 安装uwsgi报错解决

centos

在centos7中用pip install uwsgi，老是报错，原因是没有安装依赖，解决思路参考如下。

1.安装编译

yum install -y gcc* pcre-devel openssl-devel

2.安装依赖

yum install -y python-devel

3.安装uwsgi

pip install uwsgi

ubuntu

在ubuntu20.04中使用pip3 install uwsgi，和centos中报错类似，具体如下：

# pip3 install uwsgi==2.0.15

其实出现此问题原因也是因为缺少gcc编译器，建议先换阿里云源，然后安装gcc,

如果提示缺少wheel, pip3 install wheel:

# 先安装gcc
apt install -y gcc

# pip安装包
pip3 install uwsgi
