如果您选择在自己的系统中使用该代码，一定要检查是否会返回位置并且如果未对某个位置进行解析时为用户呈现一条告知性的错误消息。
At some point each developer must check his or her code into the source control system to see whether it will work with all the code others have written and checked in.
在某一时刻，每个开发人员都必须将他的或她的的代码检入到源控制系统中，以考察这些代码是否能和其他人编写并提交的代码一起工作。
The first three lines of code check out the latest version of sqlalchemy and add it as a package to the Python installation on your local system.

To determine what part of the code needs to be modified, and hence what files he'll need to check out, he views the updates made by the system designer and architect at Site a.
为了确定哪一部分的代码需要进行更改，以及需要检出哪些文件，他要浏览Site A的系统设计师和架构师所做出的更新。
You can write functional tests that run in each browser, and then implement some form of continuous integration system that runs the functional tests upon each check-in of the source code.
您可以编写在每个浏览器中运行的功能测试，然后实现一个根据源代码的每次签入运行功能测试的持续集成系统。
For instance, you can set up your CI system to execute a build that only runs unit tests during code check-ins (which is often referred to as a commit build).
例如，可以设置CI系统执行构建(通常称作提交构建)，该构建只在代码签入时运行单元测试。
Similarly, at times, some problems may occur in the system even when there has been no check engine light or trouble code signal.
同样地，有时，有些故障可能在系统中已经产生但并没有“检查发动机”灯或故障码信号显示。
