如何在调试 Python 代码之前执行 .BAT 脚本？答案

【问题标题】：How do I execute a .BAT script before debugging Python code?如何在调试 Python 代码之前执行 .BAT 脚本？
【发布时间】：2021-06-28 17:55:15
【问题描述】：

我想使用PyCharm 逐步完成一个程序。在执行程序之前，我必须先执行a.bat脚本来设置一些环境变量，否则我的程序会找不到一些库。有什么办法可以解决这个问题吗？

我尝试使用subpross(" xx.bat") 和os.system(" xx.bat")，但都失败了。

这个bat脚本是OpenVino2021.1的环境变量配置脚本。

【问题讨论】：

我会先尝试研究这个 .bat 文件，听起来你正在启动一个虚拟环境。您可以简单地将此虚拟环境添加为解释器并将其用于您的项目（文件 > 设置 > 您的项目 > Python 解释器 > 单击右上角的 cog 并添加另一个解释器（例如您的 VENV））。还要在运行配置中选择新添加的解释器（运行按钮旁边的下拉菜单 > 编辑配置，右上角）。
我尝试将bat文件的内容添加到系统环境变量中但是失败了。@matle
可以显示.bat文件的内容吗？
cmets 太多了，所以我把问题放在了问题部分。@matle

【解决方案1】：

我解决了这个问题：

执行CMD 命令。
在窗口中执行BAT脚本。
PyCharm64.exe程序的执行（我的是：C:\Program Files\JetBrains\PyCharm 2021.1.2\bin\ PyCharm64.exe）

在这种情况下，PyCharm 程序是 CMD 的子程序。
