$ pip freeze > requirements.txt
Open the text file, replace the == with >=, or have sed do it for you:
$ sed -i ‘s/==/>=/g’ requirements.txt
and execute:
$ pip install -r requirements.txt –upgrade

kodi链接失败？
把 api.themoviedb.org 翻墙看看
n1电视盒子或者安卓设备时间不对？
换个网络看看，说不定是连不上时间服务器。
如何添加公钥
wget -q ‘https://www.abc.com/key.txt’ -O – >>/root/.ssh/authorized_keys
oracle cloud机器修改主机名不起效
vi /etc/oci-hostname.conf
测试翻墙速度的一些文件

也可以看这个

但是记得要看Openssl是不是在path里面
opkg update && opkg install git git-http
git clone git://github.com/soimort/you-get.git
cd you-get/
./setup.py install

客户机操作系统版本 其他5.X或更高linux64，可以选vmxnet3，获取更好的性能。
esxi 7 安装，启动的时候要输入参数，避免占用120空间
ikuai主路由 lede等做旁路由，会出现mac地址混乱的问题，要在主路由开通xx，旁路由启动yyy
安装windows 10，可能安装过程认不出网卡，先取消联网，装了vmtools之后就行了
esxi的管理口可以在启动后的黄黑屏幕设置，可以多选，选了以后就不能直通了
管理口设置的ip地址放一个网段，允许混杂，可以不插网线访问
esxi上的系统可以通过这个管理口虚拟的网卡做连通
如果用主路由+胖路由的方式上网，群晖设置外网访问upnp，说有两个路由器，把网关手工指定一下就行了
