MOJO Series #1: Install SDK on UBUNTU

Zeyang Lin — Fri, 08 Sep 2023 10:00:00 GMT

So, THAT 35000-times-faster-than-python language, mojo, released its SDK today. This means you can install Mojo in your own environment and run mojo programs.

And here in this post, I will show you how to do it on Ubuntu.

System Requirements

Ubuntu 20.04 and later
x86-64 CPU and minimum 4 GB RAM
Python 3.8 - 3.10
g++ or clang++ compiler

My environment

Kubuntu 22.04.3
AMD CPU with 16GB RAM
Python 3.10.12
g++ 11.4.0

Install steps

1. Install Modular CLI

# switch to root first
sudo -u root -i

# then run the following command
apt-get install -y apt-transport-https &&
  keyring_location=/usr/share/keyrings/modular-installer-archive-keyring.gpg &&
  curl -1sLf 'https://dl.modular.com/bBNWiLZX5igwHXeu/installer/gpg.0E4925737A3895AD.key' |  gpg --dearmor >> ${keyring_location} &&
  curl -1sLf 'https://dl.modular.com/bBNWiLZX5igwHXeu/installer/config.deb.txt?distro=debian&codename=wheezy' > /etc/apt/sources.list.d/modular-installer.list &&
  apt-get update &&
  apt-get install -y modular

# switch back to normal user
exit

2. Verify `modular` is installed

which modular

/usr/bin/modular

3. Install Mojo SDK

modular auth <YOUR AUTH KEY> && modular install mojo

# Found release for https://packages.modular.com/mojo @ 0.2.1, installing to /home/******/.modular/pkg/packages.modular.com_mojo
# Downloads complete, setting configs...
# Configs complete, running post-install hooks...

🔥 Mojo installed! 🔥

Now run the following commands if you are using bash:

echo 'export MODULAR_HOME="/home/******/.modular"' >> ~/.bashrc
echo 'export PATH="/home/******/.modular/pkg/packages.modular.com_mojo/bin:$PATH"' >> ~/.bashrc
source ~/.bashrc

If you are using ZSH, run the following commands:

echo 'export MODULAR_HOME="/home/******/.modular"' >> ~/.zshrc
echo 'export PATH="/home/******/.modular/pkg/packages.modular.com_mojo/bin:$PATH"' >> ~/.zshrc
source ~/.zshrc

Then enter 'mojo' to start the Mojo REPL.

For tool help, enter 'mojo --help'.
For more docs, see https://docs.modular.com/mojo.

4. Add mojo to PATH

# You must replace two <USERNAME> with your own username
echo 'export MODULAR_HOME="/home/<USERNAME>/.modular"' >> ~/.bashrc

echo 'export PATH="/home/<USERNAME>/.modular/pkg/packages.modular.com_mojo/bin:$PATH"' >> ~/.bashrc

source ~/.bashrc

Now verify mojo command is accesible:

which mojo

/home/******/.modular/pkg/packages.modular.com_mojo/bin/mojo

5. Mojo REPL

MOJO 系列第一篇: 在 Ubuntu 环境下安装本地 SDK

Zeyang Lin — Fri, 08 Sep 2023 10:00:00 GMT

那个号称 比 Python 快 35000倍 的 Mojo 语言，今天终于开放了 SDK 的下载。就是说，你可以在自己的本地环境安装 Mojo 并运行 Mojo 程序了。

那么这篇文章是用来记录在 Ubuntu 环境下如何安装 SDK。

首先来看看前置条件－－官方的系统需求

System Requirements

Ubuntu 20.04 and later
x86-64 CPU and minimum 4 GB RAM
Python 3.8 - 3.10
g++ or clang++ compiler

并无苛刻之处，都2023年了这些应该都是基础配置了吧。（除非你不用 Ubuntu 系列的 Linux）

那我自己的环境如下

My environment

Kubuntu 22.04.3
AMD CPU with 16GB RAM
Python 3.10.12
g++ 11.4.0

然后你需要在 Modular 网站（https://developer.modular.com/download）上面用邮箱注册一个帐号，来获得你的 AUTHKEY 。这个 KEY 是后面步骤用来验证你的身份的。图中的 MODULAR_AUTH= 后面的部分就是你的 AUTHKEY。

满足了官方需求后，下面就是一步一步安装了。需要注意的是你似乎是需要魔法才能成功完成下面的步骤。

安装步骤

1. 安装 Modular CLI

Modular CLI 是安装 mojo 的前置条件

# 首先切换到 root 用户：
sudo -u root -i

# 然后执行以下命令：
apt-get install -y apt-transport-https &&
  keyring_location=/usr/share/keyrings/modular-installer-archive-keyring.gpg &&
  curl -1sLf 'https://dl.modular.com/bBNWiLZX5igwHXeu/installer/gpg.0E4925737A3895AD.key' |  gpg --dearmor >> ${keyring_location} &&
  curl -1sLf 'https://dl.modular.com/bBNWiLZX5igwHXeu/installer/config.deb.txt?distro=debian&codename=wheezy' > /etc/apt/sources.list.d/modular-installer.list &&
  apt-get update &&
  apt-get install -y modular

# 然后切换回你自己的普通用户：
exit

2.验证 `modular` 已经安装

在命令行执行：

which modular

如果有下面的输出则表明modular安装成功

/usr/bin/modular

如果没有任何输出，那你可能是需要魔法了。

3.安装 Mojo SDK

modular安装好后，就可以安装mojo了。

在命令行执行：

# 把下面的 <YOUR AUTH KEY> 替换成你自己的 key
modular auth <YOUR AUTH KEY> && modular install mojo

等待时间可能会比较久。。。下面就是输出，可以看到它还会安装很多 python 库到系统的 python 环境里。。。

# Found release for https://packages.modular.com/mojo @ 0.2.1, installing to /home/******/.modular/pkg/packages.modular.com_mojo
# Downloads complete, setting configs...
# Configs complete, running post-install hooks...

TEST: `mojo package`... OK

TEST: `mojo test_python.mojo`... OK
TEST: `mojo repl`... OK

🔥 Mojo installed! 🔥

Now run the following commands if you are using bash:

echo 'export MODULAR_HOME="/home/******/.modular"' >> ~/.bashrc
echo 'export PATH="/home/******/.modular/pkg/packages.modular.com_mojo/bin:$PATH"' >> ~/.bashrc
source ~/.bashrc

If you are using ZSH, run the following commands:

echo 'export MODULAR_HOME="/home/******/.modular"' >> ~/.zshrc
echo 'export PATH="/home/******/.modular/pkg/packages.modular.com_mojo/bin:$PATH"' >> ~/.zshrc
source ~/.zshrc

Then enter 'mojo' to start the Mojo REPL.

For tool help, enter 'mojo --help'.
For more docs, see https://docs.modular.com/mojo.

4.添加 `mojo` 到 `PATH`

# 把下面两个 <USERNAME> 替换成你自己的用户名
echo 'export MODULAR_HOME="/home/<USERNAME>/.modular"' >> ~/.bashrc

echo 'export PATH="/home/<USERNAME>/.modular/pkg/packages.modular.com_mojo/bin:$PATH"' >> ~/.bashrc

# 重新加载 .bachrc 令改动生效
source ~/.bashrc

现在验证 mojo 命令是否已经能用了:

which mojo

若输出为下面内容则表示安装成功：

/home/******/.modular/pkg/packages.modular.com_mojo/bin/mojo

5. 体验 Mojo REPL

在命令行执行：

mojo

就进到了 mojo 的互动编程环境。熟悉 Python 或其它类似语言的小伙伴对这个一定不陌生。

Welcome to Mojo! 🔥 Expressions are delimited by a blank line. Type :mojo help for further assistance.

那么至此 mojo 的基础开发环境就已经搭建好了，在下一篇文章中我会记录如何运行最基础的 “Hello world” 程序。

Bonus Round: 看看 mojo 目录的文件夹结构
