对于变量名称:"输入HOME"，对于变量值:"输入C:\Users\.

如果 HOME 变量已经存在，只需在当前值和新路径之间放置一个分号.当应用程序使用 HOME 变量时，它可能会按顺序搜索内容.如果您希望首先找到您的新路径，请将其放在列表的首位.

点击好的"，然后重新启动任何正在运行 pdb 的应用程序(cmd.exe 或其他).确保您的 .pdbrc 文件位于 C:\Users\ 中.当您再次运行 pdb 时，它现在应该会在启动时读取您的 .pdbrc 文件.

How can I define .pdbrc on my Windows machine?

My .pdbrc file:

alias sl s;;l
alias nl n;;l
alias cl c;;l

After reading the answer to this question, I tried putting it in C:\Users\<my_user>. Starting pdb (using pdb.set_trace()), I tried the aliases. They weren't recognized.

I'd like to know how to set a .pdbrc both globally, and for a virtual environment.

解决方案

pdb looks for the HOME system variable which is not defined by default in Windows. You have to define it yourself.

This issue arises because every user in a *nix operating system (Linux, Unix, Darwin, etc.) has a /home directory where they can put run codes like .pdbrc. The path to this directory lives in a system variable (HOME) that applications use to point to a user's personal files. Windows doesn't really have anything like that. The closest analogy to /home on Windows is probably C:\Users\<username>.

Here is how to define a HOME system variable that contains the path C:\Users\<username>. Left click on the startup button and then right click on "Computer" and select "Properties".

On the top left, click the "Advanced system settings" link.

This brings up the "System Properties" dialog. On the "Advanced" tab, press the "Environment variables..." button.

This brings up the "Environment Variables..." dialog. In the top section for "User variables for <username>", press the "New..." button.

For "Variable name:" put "HOME" and for "Variable value:" put C:\Users\<username>.

If a HOME variable already exists, just put a semi-colon between whatever is the current value and the new path. When an application uses the HOME variable, it will likely search the contents sequentially. If you want your new path to be found first, put it first in the list.

Hit "Okay" a bunch and then restart whatever application (cmd.exe or otherwise) is running pdb. Make sure that your .pdbrc file is in C:\Users\<username>. When you run pdb again, it should now read your .pdbrc file on startup.
