git解決合并沖突的方法：1、編輯有沖突的文件，并刪除文件中的特殊符號，根據需求修改代碼；2、將指定文件添加到暫存區，并將指定的分支提交到主干，執行提交即可，其中使用“git commit”命令時不能帶文件名, 加文件名會報錯。

git怎么解決合并沖突
git沖突
多個分支代碼合并到一個分支時，兩個分支中修改了同一個文件，不管是什么地方修改，都會產生；
還有一種 兩個分支中修改了同一個文件的名稱時會產生。
原因
合并分支時，兩個分支在同一個文件有兩套完全不同的修改。Git 無法替
我們決定使用哪一個。必須人為決定新代碼內容。
解決方法
編輯有沖突的文件，刪除特殊符號，決定要使用的內容
添加到暫存區
執行提交（注意：此時使用 git commit 命令時不能帶文件名, 加文件名會報錯，成功提交后，merging消失）
示例如下：
1、沖突的產生
1.1、主干分支代碼
在主干分支有兩個文件
main.cpp
#include <stdio.h> #include <string.h> int main() { char data[100] = "my branch name is master"; int length = strlen(data); for(int i = 0; i < length; i++) { printf("%c", data[i]); } printf("branch mastern"); return 0; }
README.md
this is master branch
這個時候tom和jack分別拉取了主干分支的代碼，并進行了修改。
1.2、tom修改代碼提交合并
tom創建A分支并對文件做了以下修改
main.cpp
#include <stdio.h> #include <string.h> int main() { char data[100] = "my branch name is A"; int length = strlen(data); for(int i = 0; i < length; i++) { printf("%c", data[i]); } printf("branch AAAn"); return 0; }
README.md
this is AAA branch
提交代碼并合并到主干
lng@DESKTOP-9TD21KL MINGW64 ~/Desktop/tom/kaol (A) $ git add . lng@DESKTOP-9TD21KL MINGW64 ~/Desktop/tom/kaol (A) $ git commit -m "A分支代碼提交" [A ccb2626] A分支代碼提交 2 files changed, 3 insertions(+), 3 deletions(-) lng@DESKTOP-9TD21KL MINGW64 ~/Desktop/tom/kaol (A) $ git push origin A Enumerating objects: 7, done.

1.3、jack修改代碼提交合并
jack對代碼做了如下修改
main.cpp
#include <stdio.h> #include <string.h> int main() { char data[100] = "my branch name is B"; int length = strlen(data); for(int i = 0; i < length; i++) { printf("%c", data[i]); } printf("branch BBBn"); return 0; }
README.md
this is BBB branch
提交代碼并合并到主干
lng@DESKTOP-9TD21KL MINGW64 ~/Desktop/jack/kaol (B) $ git add . lng@DESKTOP-9TD21KL MINGW64 ~/Desktop/jack/kaol (B) $ git commit -m "B分支代碼提交" [B bdcbe03] B分支代碼提交 2 files changed, 3 insertions(+), 3 deletions(-) lng@DESKTOP-9TD21KL MINGW64 ~/Desktop/jack/kaol (B) $ git push origin B Enumerating objects: 53, done. Counting objects: 100% (53/53), done. Delta compression using up to 12 threads Compressing objects: 100% (34/34), done. Writing objects: 100% (50/50), 4.66 KiB | 2.33 MiB/s, done.

push時產生沖突
lng@DESKTOP-9TD21KL MINGW64 ~/Desktop/jack/kaol (master) $ git push origin master To https://gitee.com/lingpe/kaol.git ! [rejected] master -> master (fetch first) error: failed to push some refs to 'https://gitee.com/lingpe/kaol.git' hint: Updates were rejected because the remote contains work that you do hint: not have locally. This is usually caused by another repository pushing 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. lng@DESKTOP-9TD21KL MINGW64 ~/Desktop/jack/kaol (master) $
2、解決沖突
接下來就是如何解決沖突
切換回B分支，然后拉取主干分支代碼
lng@DESKTOP-9TD21KL MINGW64 ~/Desktop/jack/kaol (B) $ git pull origin master remote: Enumerating objects: 7, done. remote: Counting objects: 100% (7/7), done. remote: Compressing objects: 100% (3/3), done. remote: Total 4 (delta 1), reused 0 (delta 0), pack-reused 0 Unpacking objects: 100% (4/4), 356 bytes | 178.00 KiB/s, done. From https://gitee.com/lingpe/kaol * branch master -> FETCH_HEAD 40c0115..ccb2626 master -> origin/master Auto-merging main.cpp CONFLICT (content): Merge conflict in main.cpp Auto-merging README.md CONFLICT (content): Merge conflict in README.md Automatic merge failed; fix conflicts and then commit the result.
拉取失敗，可以看到提示信息，告訴我們哪個文件產生了沖突。
直接打開main.cpp文件，可以看到有以下特殊字符，提示我們哪一行代碼產生了沖突。
#include <stdio.h> #include <string.h> int main() { <<<<<<< HEAD char data[100] = "my branch name is B"; ======= char data[100] = "my branch name is A"; >>>>>>> ccb26269f42245dfcbedfbf2218419c5ab7f2787 int length = strlen(data); for(int i = 0; i < length; i++) { printf("%c", data[i]); } <<<<<<< HEAD printf("branch BBBn"); ======= printf("branch AAAn"); >>>>>>> ccb26269f42245dfcbedfbf2218419c5ab7f2787 return 0; }
直接在文件中手動解決沖突。刪除文件中的特殊字符，然后根據需求修改代碼。
#include <stdio.h> #include <string.h> int main() { char data[100] = "my branch name is B and A"; int length = strlen(data); for(int i = 0; i < length; i++) { printf("%c", data[i]); } printf("branch BBBn"); printf("branch AAAn"); return 0; } ~
同理，對README.md，手動解決沖突。
this is BBB and AAA branch
解決完沖突后提交到B分支
lng@DESKTOP-9TD21KL MINGW64 ~/Desktop/jack/kaol (B|MERGING) $ git add . lng@DESKTOP-9TD21KL MINGW64 ~/Desktop/jack/kaol (B|MERGING) $ git commit -m "解決沖突" [B f30e1ea] 解決沖突 lng@DESKTOP-9TD21KL MINGW64 ~/Desktop/jack/kaol (B) $ git push origin B Enumerating objects: 10, done. Counting objects: 100% (10/10), done. Delta compression using up to 12 threads Compressing objects: 100% (3/3), done. Writing objects: 100% (4/4), 405 bytes | 405.00 KiB/s, done. Total 4 (delta 1), reused 0 (delta 0), pack-reused 0 remote: Powered by GITEE.COM [GNK-6.2] To https://gitee.com/lingpe/kaol.git bdcbe03..f30e1ea B -> B lng@DESKTOP-9TD21KL MINGW64 ~/Desktop/jack/kaol (B) $
最后將B分支合并到主干，就不會產生沖突了
lng@DESKTOP-9TD21KL MINGW64 ~/Desktop/jack/kaol (B) $ git checkout master Switched to branch 'master' Your branch and 'origin/master' have perged, and have 1 and 1 different commits each, respectively. (use "git pull" to merge the remote branch into yours) lng@DESKTOP-9TD21KL MINGW64 ~/Desktop/jack/kaol (master) $ git merge B Updating bdcbe03..f30e1ea Fast-forward README.md | 2 +- main.cpp | 4 ++-- 2 files changed, 3 insertions(+), 3 deletions(-) lng@DESKTOP-9TD21KL MINGW64 ~/Desktop/jack/kaol (master) $ git push origin master Total 0 (delta 0), reused 0 (delta 0), pack-reused 0 remote: Powered by GITEE.COM [GNK-6.2] To https://gitee.com/lingpe/kaol.git ccb2626..f30e1ea master -> master lng@DESKTOP-9TD21KL MINGW64 ~/Desktop/jack/kaol (master) $
至此，沖突成功解決
可以看下主干分支的代碼
main.cpp
#include <stdio.h> #include <string.h> int main() { char data[100] = "my branch name is B and A"; int length = strlen(data); for(int i = 0; i < length; i++) { printf("%c", data[i]); } printf("branch BBBn"); printf("branch AAAn"); return 0; }
README.md
this is BBB and AAA branch
