    hint: to the same ref. You may want to first integrate the remote changes
    hint: (e.g., 'git pull ...') before pushing again.
    hint: See the 'Note about fast-forwards' in 'git push --help' for details.

    fatal: Unable to create 'D:/网页制作软件/Git/web/.git/index.lock': File exists.

    If no other git process is currently running, this probably means a
    git process crashed in this repository earlier. Make sure no other git
    process is running and remove the file manually to continue.

解决办法：$ rm -f ./.git/index.lock

然后 git add TTMS
