別的不在多說。由於樓主上傳沒問題，僅僅遇到了 Can't push, because no remotes are defined問題，這裏着重介紹下樓主怎麼解決的。
按上面第二個鏈接裏Wes Eklund所說的，在項目工程下找到 .git/directory，用記事本方式打開，在文件最後附加如下內容。
<code style="margin:0px; padding:0px; border:0px; vertical-align:baseline; font-family:Consolas,Menlo,Monaco,'Lucida Console','Liberation Mono','DejaVu Sans Mono','Bitstream Vera Sans Mono','Courier New',monospace,serif; white-space:inherit"><span class="pun" style="margin:0px; padding:0px; border:0px; vertical-align:baseline; background:transparent">[</span><span class="pln" style="margin:0px; padding:0px; border:0px; vertical-align:baseline; background:transparent">remote </span><span class="str" style="color:#8000;margin:0px; padding:0px; border:0px; vertical-align:baseline; background:transparent">"origin"</span><span class="pun" style="margin:0px; padding:0px; border:0px; vertical-align:baseline; background:transparent">]</span><span class="pln" style="margin:0px; padding:0px; border:0px; vertical-align:baseline; background:transparent"> url </span><span class="pun" style="margin:0px; padding:0px; border:0px; vertical-align:baseline; background:transparent">=</span><span class="pln" style="margin:0px; padding:0px; border:0px; vertical-align:baseline; background:transparent"> https</span><span class="pun" style="margin:0px; padding:0px; border:0px; vertical-align:baseline; background:transparent">:</span><span class="com" style="color:#808080;margin:0px; padding:0px; border:0px; vertical-align:baseline; background:transparent">//github.com/YOURPROFILE/YOURREPO.git</span></code>這裏有個插曲。樓主的.git目錄下沒有發現directory文件。找了半天，最後決定死馬當活馬醫，在config裏添加了上述代碼。事實證明我是對了~
