Question

我目前正在为学校构建Adblock Plus的源代码项目，我正在使用Autoinstall插件轻松部署到我的浏览器，但Python中提供的构建工具似乎只能工作当我出于某种原因在Git Bash中执行它们时。

当我尝试执行命令时，这是错误消息 Windows命令行：

C:\Users\Evert\Documents\GitHub\adblockplus>python build.py autoinstall 8888

这对我来说不是一个大问题，因为它确实构建了，但我忍不住想知道：这两种环境之间有什么区别这个脚本有用吗？

问题似乎是git.exe不在您的Windows PATH中，它肯定是在Git Bash :)中。对于git：

，您有两个“未找到”错误

在ensure_dependencies.py第106行，执行command。每the source，命令为['git', 'rev-parse', '--revs-only', rev + '^{commit}']。
在packager.py第46行，执行['git', 'rev-list', 'HEAD']。

这两个都缺失git。要在运行python build.py之前修复，请执行

path %PATH%;c:\<wherever git.exe is located>

或使用“控制面板”将git.exe的位置添加到系统路径。

修改如果您的Git安装来自GitHub，this answer会提供有关向您的PATH添加Git的详细信息。

Python脚本在Windows命令行中抛出WindowsError，适用于Git Bash
