git status

On branch master
Your branch is up to date with ‘origin/master’.

nothing to commit, working tree clean

原因

error: cannot lock ref ‘refs/remotes/origin/fix/po_sent_email_histories_pdf_price_wrong’: ‘refs/remotes/origin/fix’ exists; cannot create ‘refs/remotes/origin/fix/po_sent_email_histories_pdf_price_wrong’

refs/remotes/origin/fix 已经存在,导致 refs/remotes/origin/fix/po_sent_email_histories_pdf_price_wrong 无法创建。更好的做法,本地清掉 refs/remotes/origin/fix 即可。不过上面的命令全清也不错,公司的代码分支是有点乱😅

Reference

git pull fails “unable to resolve reference” “unable to update local ref”
