1 解决方法
在python开发工程目录下有一个".vscode"文件夹,在该文件夹下有一个launch.json文件,在 launch.json中添加一行cwd的信息,就可以解决open找不到文件的问题。
添加行如下所示:
"cwd": "${fileDirname}",
完整的launch.json如下所示:
{ // Use IntelliSense to learn about possible attributes. // Hover to view descriptions of existing attributes. // For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387 "version": "0.2.0", "configurations": [ { "name": "Python: 当前文件", "type": "python", "request": "launch", "program": "${file}", "console": "integratedTerminal", "cwd": "${fileDirname}", } ] }
