 ```bash
-sudo apt-get update
-sudo apt-get install -y python3 python3-dev python3-setuptools gcc libtinfo-dev zlib1g-dev build-essential cmake libedit-dev libxml2-dev
+apt-get update
+apt-get install -y python3 python3-dev python3-setuptools gcc zlib1g-dev build-essential cmake libedit-dev

 ```bash
 git clone --recursive https://github.com/tile-ai/tilelang.git
