[在合并小部件](#merge-request-ability-to-merge-widget)的[合并請求功能](#merge-request-ability-to-merge-widget)上方顯示. 根據管道的狀態，可以顯示幾條消息. ### “Checking pipeline status”[](#checking-pipeline-status "Permalink") This message is shown when the merge request has no pipeline associated with the latest commit yet and [Pipelines must succeed](../user/project/merge_requests/merge_when_pipeline_succeeds.html#only-allow-merge-requests-to-be-merged-if-the-pipeline-succeeds) is turned on. This might be because: * GitLab 尚未完成創建管道. * 您正在使用外部 CI 服務，但 GitLab 尚未收到該服務的回音. * 您沒有在項目中使用 CI / CD 管道. 創建管道后，該消息將更新為管道狀態. 注意：當前，如果您刪除合并請求的最新管道，則將顯示此消息，而不是有意義的錯誤消息. 這是一個已知問題，應盡快解決. ## Merge request ability to merge widget[](#merge-request-ability-to-merge-widget "Permalink") 合并請求狀態窗口小部件顯示" **合并"**按鈕以及合并請求是否準備就緒. 如果合并請求無法合并，則會顯示原因. 如果管道仍在運行，則將" **合并"**按鈕替換為" **管道成功后合并"**按鈕. 如果[**合并火車**](merge_request_pipelines/pipelines_for_merged_results/merge_trains/index.html)被啟用，按鈕要么**加入到合并列車**或**添加到合并火車時管道成功** . ### “A CI/CD pipeline must run and be successful before merge”[](#a-cicd-pipeline-must-run-and-be-successful-before-merge "Permalink") 如果在項目中啟用了" [管道必須成功"](../user/project/merge_requests/merge_when_pipeline_succeeds.html#only-allow-merge-requests-to-be-merged-if-the-pipeline-succeeds)設置，并且管道尚未成功運行，則會顯示此消息. 如果尚未創建管道，或者正在等待外部 CI 服務，則這也適用. 如果您的項目不使用管道，則應禁用**管道必須成功**才能接受合并請求.
