Mojo-SDK详细安装教程
Mojo-SDK安装
运行环境：windows11+wsl2（ubuntu1804）
截至20230909，windows,mac系统暂时不支持
step1:
Install VS Code, the WSL extension, and the Mojo extension.
step2:
Install Ubuntu 22.04 for WSL and open it.
step3:
In the Ubuntu terminal, install the Modular CLI:
The script requires root or sudo privileges to run.
curl https://get.modular.com | \
MODULAR_AUTH=mut_b2c22398bcc949a6a803dfe01d09fc06 \
sh -
可能会出现报错：
modular: error while loading shared libraries: libtinfo.so.6: cannot open shared object file: No such file or directory
解决（这里优点乱，试了好几种方法，后面莫名其妙，运行这个命令就没报错了）：
sudo apt install libevent-dev ncurses-dev build-essential bison pkg-config
继续执行上面脚本，出现如下 not found报错
Processing triggers for man-db (2.8.3-2ubuntu0.1) ...
modular: /lib/x86_64-linux-gnu/libm.so.6: version `GLIBC_2.29' not found (required by modular)
modular: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.28' not found (required by modular)
modular: /usr/lib/x86_64-linux-gnu/libstdc++.so.6: version `GLIBCXX_3.4.26' not found (required by modular)
继续解决上述报错：
检查版本：
(torch) dongyongfei786@DESKTOP-3QNKDLL:~$ strings /lib/x86_64-linux-gnu/libc.so.6 |grep GLIBC_
GLIBC_2.2.5
GLIBC_2.2.6

解决方案：添加一个高级版本系统的源，直接升级libc6.
编辑源：
sudo vi /etc/apt/sources.list
添加高版本的源
deb http://th.archive.ubuntu.com/ubuntu jammy main #添加该行到文件
运行升级
sudo apt update
sudo apt install libc6
再次检查版本

再次运行step3脚本，没有再报错
step4：
Install the Mojo SDK:
modular install mojo

但是能正常查看版本，安装成功了吗？应该是bug
(torch) dongyongfei786@DESKTOP-3QNKDLL:~$ modular --version
modular 0.1.4 (6b54d308)
貌似没报错了
(torch) dongyongfei786@DESKTOP-3QNKDLL:~$ mojo # 这里应该还是有点问题的，没有进入类似python的窗口
(torch) dongyongfei786@DESKTOP-3QNKDLL:~$ mojo --version
mojo 0.2.1 (64d14e85)
