终端进程启动失败：A native exception occurred during launch (VS Code Integrated Terminal)

Question

我正在使用 ASP.NET MVC 开发 Web 应用程序。要运行它，我使用以下 shell 命令：

dotnet restore ProjectDirectory

接着

dotnet run --project ProjectDirectory

如果我在我的命令 shell 中运行它们，一切正常。但是我的代码编辑器是 VS Code，所以我想让它在集成终端中运行这些命令。我已经在其文件launch.json 和tasks.json 中配置了它的行为：

// launch.json

            "preLaunchTask": "restore",

            "args": ["run", "--project", "${workspaceFolder}"],
            "cwd": "${workspaceFolder}",
            "stopAtEntry": false,
            "serverReadyAction": {
                "action": "openExternally",

                "/Views": "${workspaceFolder}/Views"
            }
        },
        {
            "name": ".NET Core Attach",
            "type": "coreclr",
            "request": "attach"
        }
    ]
}

// tasks.json

{
    "version": "2.0.0",
    "tasks": [
        {
            "label": "build",
            "command": "dotnet",
            "type": "process",
            "args": [
                "build",
                "${workspaceFolder}/MyWebApp.csproj",
                "/property:GenerateFullPaths=true",
                "/consoleloggerparameters:NoSummary"
            ],
            "problemMatcher": "$msCompile"
        },
        {
            "label": "publish",
            "command": "dotnet",
            "type": "process",
            "args": [
                "publish",
                "${workspaceFolder}/MyWebApp.csproj",
                "/property:GenerateFullPaths=true",
                "/consoleloggerparameters:NoSummary"
            ],
            "problemMatcher": "$msCompile"
        },
        {
            "label": "watch",
            "command": "dotnet",
            "type": "process",
            "args": [
                "watch",
                "run",
                "${workspaceFolder}/MyWebApp.csproj",
                "/property:GenerateFullPaths=true",
                "/consoleloggerparameters:NoSummary"
            ],
            "problemMatcher": "$msCompile"
        },
        // Here is my preLaunchTask
        {
            "label": "restore",
            "command": "dotnet",
            "type": "process",
            "args": [
                "restore",
                "${workspaceFolder}"
            ],
            "problemMatcher": "$msCompile"
        }
    ]
}

配置后我试了一下。我按了F5。集成终端打开，并尝试运行

dotnet restore ProjectDirectory

但随后它显示了以下错误消息：

终端进程启动失败：启动时出现本机异常（CreateProcess failed）

我试过的

1. 我打开 VS Code 文档并进行了一些研究。我只找到了一个关于排除集成终端故障的page。

2. 我尝试了上面故障排除页面中的所有建议。他们没有帮助我。

3. 上网冲浪（包括 Stack Overflow）。我没有找到有用的页面（不包括上面描述的故障排除页面）。

4. 现在我问我自己的问题。

看起来问题出在 tasks.json 文件中的还原任务中的 args。 restore 命令不使用 --project 标志，因此您应该将其从 args 数组中删除。

您的恢复任务应如下所示：

{
    "label": "restore",
    "command": "dotnet",
    "type": "process",
    "args": [
        "restore",
        "${workspaceFolder}"
    ],
    "problemMatcher": "$msCompile"
}

您还应确保launch.json 文件中的preLaunchTask 属性设置为“恢复”。

"preLaunchTask": "restore",

进行这些更改后，尝试再次运行您的项目并查看问题是否已解决。
