ennnn,可能仅仅是因为网不好，或者pycharm重启，， 很有可能是因为科学.网-代理所致 

反正我的是取消代理解决的。。。

先：

git config --global http.proxy http://127.0.0.1:1080
git config --global https.proxy http://127.0.0.1:1080

重启git客户端，再：

git config --global --unset http.proxy 
git config --global --unset https.proxy 

重启git客户端，再：

git add .
git commit -m "提交备注"
git push

en就是这样解决的。

 还有。。。
