尝试在 Ubuntu 16.04 虚拟机中安装“xgboost”时出现“找不到命令”错误

Question

I'm trying to install xgboost in an Ubuntu 16.04 virtual machine.

I'm following this guide and ran this command:

cmake ..

I got this error:

-bash: cmake: command not found

What am I doing wrong and how can I get rid of this error?

Answer 1

Try this:

sudo apt-get install software-properties-common
sudo add-apt-repository ppa:george-edison55/cmake-3.x
sudo apt-get update 
sudo apt-get install cmake

UPDATE: Or you can just use pip:

sudo pip3 install xgboost

Answer 2

It appears you're getting this error because you don't have the cmake command installed, you can fix this by running:

sudo apt install cmake

I don't know if you've missed this but you can also install xgboost using pip (or in your case pip3 ), like this:

pip3 install xgboost

NOTE : depending on how your user/project is set up you might need to use the sudo command to grant pip3 write privileges to certain (root) directories, if this is the case, you'd use:

sudo pip3 install xgboost

NOTE: if you don't have pip3 installed, you can install it using:

sudo apt install python3 python3-pip

Good luck.
