为什么我的新Rust项目会将可执行文件发送到以前的项目target/debug & target/release文件夹？

Question

我在Ubuntu18.04上的VSCode Rust项目的路径是~/Documents/VSCode_Projects/VSCode_Rust_Projects。

在VSCode_Rust_Projects文件夹中，我有两个工作正常的项目。

我刚刚在文件夹VSCode_Rust_Projects中创建了第三个新项目，由于某种原因，当我将cargo build作为任务在集成开发环境中执行时，调试可执行文件会被发送到上一个项目的目标/调试folder...so文件夹，而不会在当前项目的工作文件夹中生成目标/调试文件夹。为什么？?

任务配置为：

{
    "version": "2.0.0",
    "tasks": [
        {
            "type": "cargo",
            "command": "build",
            "problemMatcher": [
                "$rustc"
            ],
            "group": "build",
            "label": "rust: cargo build"
        },
        {
            "type": "cargo",
            "command": "check",
            "problemMatcher": [
                "$rustc"
            ],
            "group": "build",
            "label": "rust: cargo check"
        },
        {
            "type": "cargo",
            "command": "clean",
            "problemMatcher": [
                "$rustc"
            ],
            "group": "none",
            "label": "rust: cargo clean"
        },
        {
            "type": "cargo",
            "command": "run",
            "problemMatcher": [
                "$rustc"
            ],
            "label": "rust: cargo run"
        },
        {
            "type": "cargo",
            "command": "test",
            "problemMatcher": [
                "$rustc"
            ],
            "group": "test",
            "label": "rust: cargo test"
        },
        {
            "type": "cargo",
            "command": "build",
            "args": [
                "--release"
            ],
            "problemMatcher": [
                "$rustc"
            ],
            "group": "build",
            "label": "rust: cargo build --release"
        }
    ]
}

我被难住了！我无法在我的新项目中生成目标文件夹。

在上一个项目中，我忘记设置了CARGO_TARGET_DIR cargo环境变量，并将其保存在.bashrc文件中。设置此选项将导致所有构建被放置在指定的目录中；注释掉该设置并执行"source ~/.bashrc“可以修复所有问题。
