                         [--lockfile-out LOCKFILE_OUT] [--lockfile LOCKFILE]

Remove requires, build-requires or python-requires from an existing lockfile.
References can be supplied with and without revisions like "--
requires=pkg/version",

options:
  -h, --help            show this help message and exit
  --out-file OUT_FILE   Write the output of the command to the specified file
                        instead of stdout.
  -v [V]                Level of detail of the output. Valid options from less
                        verbose to more verbose: -vquiet, -verror, -vwarning,
                        -vnotice, -vstatus, -v or -vverbose, -vv or -vdebug,
                        -vvv or -vtrace
  -cc CORE_CONF, --core-conf CORE_CONF
                        Define core configuration, overwriting global.conf
                        values. E.g.: -cc core:non_interactive=True
  --requires REQUIRES   Remove references to lockfile.
  --build-requires BUILD_REQUIRES
                        Remove build-requires from lockfile
  --python-requires PYTHON_REQUIRES
                        Remove python-requires from lockfile
  --config-requires CONFIG_REQUIRES
                        Remove config-requires from lockfile
  --lockfile-out LOCKFILE_OUT
                        Filename of the created lockfile
  --lockfile LOCKFILE   Filename of the input lockfile

conan lock remove 命令能够从现有的 lockfile 中移除 requires、build_requires、python_requires 或 config_requires 条目。

例如，如果我们有以下 conan.lock

$ cat conan.lock
{
    "version": "0.5",
    "requires": [
        "math/1.0#85d927a4a067a531b1a9c7619522c015%1702683583.3411012",
        "engine/1.0#fd2b006646a54397c16a1478ac4111ac%1702683583.3544693"
    ],
    "build_requires": [
        "cmake/1.0#85d927a4a067a531b1a9c7619522c015%1702683583.3411012",
        "ninja/1.0#fd2b006646a54397c16a1478ac4111ac%1702683583.3544693"
    ],
    "python_requires": [
        "mytool/1.0#85d927a4a067a531b1a9c7619522c015%1702683583.3411012",
        "othertool/1.0#fd2b006646a54397c16a1478ac4111ac%1702683583.3544693"
    ]
}

conan lock remove 命令

$ conan lock remove --requires="math/*" --build-requires=cmake/1.0 --python-requires="*tool/*"

将产生以下 conan.lock

$ cat conan.lock
{
    "version": "0.5",
    "requires": [
        "engine/1.0#fd2b006646a54397c16a1478ac4111ac%1702683583.3544693"
    ],
    "build_requires": [
        "ninja/1.0#fd2b006646a54397c16a1478ac4111ac%1702683583.3544693"
    ],
    "python_requires": [
    ]
}

可以指定不同的模式

• 通过版本范围表达式移除，例如 --requires="math/[>=1.0 <2]"，也可以

• 移除特定版本：--requires=math/1.0#revision

• 移除给定“团队”用户的锁定依赖项 --requires=*/*@team*

conan lock remove 命令可以用于

• 与 conan lock add 结合使用时，可以强制将锁定的版本降级到旧版本。由于 conan lock add 总是添加并排序顺序，导致新版本具有高优先级，因此仅使用 add 无法强制回退到旧版本。但先使用 conan lock remove，然后使用 conan lock add，就可以做到。

• conan lock remove 可以解锁某些依赖项，从而生成一个不完整的 lockfile，该 lockfile 可与 --lockfile-partial 一起使用，以解析已解锁依赖项的最新可用版本，同时保持其他依赖项的锁定状态。
