一、 下载repo 

直接安装repo会报错。

zjh@ubuntu:~/work/linux_Sunplus/app$ sudo apt-get install repo
Reading package lists... Done
Building dependency tree       
Reading state information... Done
E: Unable to locate package repo

( 在ubuntu18.04上可以直接安装，但在20.04上就算执行了sudo apt-get update也是不能直接安装的)

curl https://storage.googleapis.com/git-repo-downloads/repo > ~/bin/repo
chmod a+x ~/bin/repo

export PATH=~/bin:$PATH

二、运行repo

 repo init -u ssh://xxxx你的库地址    --repo-url=https://mirrors.tuna.tsinghua.edu.cn/git/git-repo/

可以会遇到以下错误：

1、  repo init 会报

/usr/bin/env: ‘python’: No such file or directory

解决方案：

    sudo ln -s /usr/bin/python3  /usr/bin/python

    如果没有安装则需要安装python3  ( sudo apt-get install python3)

2、报以下错误：

Traceback (most recent call last):
  File "/home/zjh/work/linux_Sunplus/app/.repo/repo/main.py", line 689, in <module>
    _Main(sys.argv[1:])
  File "/home/zjh/work/linux_Sunplus/app/.repo/repo/main.py", line 665, in _Main
    result = run()
  File "/home/zjh/work/linux_Sunplus/app/.repo/repo/main.py", line 658, in <lambda>
    run = lambda: repo._Run(name, gopts, argv) or 0
  File "/home/zjh/work/linux_Sunplus/app/.repo/repo/main.py", line 299, in _Run
    result = cmd.Execute(copts, cargs)

    self._ConfigureUser(opt)
  File "/home/zjh/work/linux_Sunplus/app/.repo/repo/subcmds/init.py", line 172, in _ConfigureUser
    name = self._Prompt('Your Name', mp.UserName)
  File "/home/zjh/work/linux_Sunplus/app/.repo/repo/project.py", line 665, in UserName
    self._LoadUserIdentity()
  File "/home/zjh/work/linux_Sunplus/app/.repo/repo/project.py", line 678, in _LoadUserIdentity
    u = self.bare_git.var('GIT_COMMITTER_IDENT')
  File "/home/zjh/work/linux_Sunplus/app/.repo/repo/project.py", line 3189, in runner
    raise GitError('%s %s: %s' %
error.GitError: manifests var: 
*** Please tell me who you are.

Run

  git config --global user.email "you@example.com"
  git config --global user.name "Your Name"
 

解决方案：

    按上面提示进行设置即可

  git config --global user.email "you@example.com"

  git config --global user.name "Your Name"

三、同步代码

repo sync
