fatal: Could not read from remote repository.以及bash： $: command not found

git clone报错：
fatal: Could not read from remote repository. Please make sure you have the correct access rights and the repository exists.
需要本地ssh配置
参考
但是输入ssh-keygen -t rsa -C "your Emil"
报错：
bash： $: command not found
试了各种方法，最后用ssh-keygen -o解决
参考
还有一个坑就是，复制ssh记得复制前面的“ssh-rsa ”
