Project code development method and system

The embodiment of the invention provides a project code development method and system. The method and the device relate to the field of software development, and can avoid the problem that the local running test result of the project code in a developer is inconsistent with the running test result of other developers on the project code due to different dependent numbers and versions of an operating system and installation of a local computer of the developer. The method comprises the following steps: a client sends a second request message to a server; wherein the second request message is used for requesting a second sub-project code; the client receives the second sub-project code sent by the server, and modifies the second sub-project code to obtain a first sub-project code; the clientsends the first sub-project code to the server; and the server receives the first sub-project code from the client, updates the total code of the target project according to the first sub-project code, and operates the updat
