输入命令：
pip3 install uwsgi
报错提示如下：

前面的报错就省略了，主要看最后几行。提示我找不到Python.h文件，大概问题就出现在python3的环境下。我目前的python3是3.8.0，pip3也是同样的版本，问题就是出现在其他地方。（如果是这里版本不匹配的朋友可以试试把python3或者pip3的python3版本换成一样的）
然后我面向百度搜索发现，其他人的解决方法是：
sudo apt-get install -y python3-dev
然后我照做后提示我：
Reading package lists... Done Building dependency tree Reading state information... Done python3-dev is already the newest version (3.6.7-1~18.04). 0 upgraded, 0 newly installed, 0 to remove and 3 not upgraded.
哦豁，提示我已经存在，但是版本是3.6.9。这很有可能就是问题所在，于是我是这样做的：删除然后下载对应版本。
sudo aptitude remove python3-dev # 用aptitude可以删除相关的依赖包 sudo aptitude install python3.8-dev
最后，成功了！
