根据您的最低稳定性设置，该软件包在足够稳定的版本中不可用

问题描述

我不太明白 Composer 如何使用最低稳定性设置.

I don't really understand how Composer works with the minimum-stability setting.

我有两个包裹.比方说，PackageA 和 PackageB.

I have two packages. Let's say, PackageA and PackageB.

PackageA的composer.json文件如下:

{
    "name": "vendor/packagea",
    "minimum-stability": "dev",
    "require": {
        "vendor/packageb": "dev"
    }
}

所以 PackageA 需要 PackageB.PackageB 的 json 长这样:

So PackageA requires PackageB. The json of PackageB looks like this:

{
    "name": "vendor/packageb",
    "minimum-stability": "dev"
}

所以两者都说最低稳定性是dev.所以我假设当我这样做时:

So both say minimum stability are dev. So I assume that when I do:

composer create-project vendor/packagea

但随后它抱怨消息:

[InvalidArgumentException]
Could not find package vendor/packagea with stability stable.

我觉得奇怪，因为我认为将最低稳定性设置为 dev 会将包从其开发"分支中拉出.在 github 的情况下总是 dev-master.

Which I find strange, because I would assume that setting the minimum stability to dev would pull the package from its "development" branch. Which in the case of github is always dev-master.

所以我尝试通过告诉 composer 使用哪个分支来安装它:

So I tried to install it by telling composer what branch to use:

composer create-project vendor/packagea testFolder dev-master

然后它抱怨它找不到 PackageB:

But then it complains that it can't find PackageB:

Installing dependencies (including require-dev)
Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - The requested package vendor/packageb dev could not be found.

那么我该如何安装我的包呢?我还在开发，所以我还不想为 PackageA 和 PackageB 创建一个版本...

Then how am I able to install my package? I'm still developing so I dont want to create a release for PackageA and PackageB yet...

推荐答案

有两个问题:

在 create-project 中，默认情况下该命令使用稳定的稳定性来查找要安装的包，这就是为什么如果您指定 dev-master 而不是默认情况下它可以工作的原因.但是，您也可以运行 composer create-project vendor/packagea -s dev

In create-project, by default the command uses the stable stability to look for the package to install, that's why it works if you specify dev-master but not by default. You could however also run composer create-project vendor/packagea -s dev

在安装依赖项之后，我猜你的包不存在于一个名为 dev 的版本中，所以如果你需要它，它就找不到它.要求 dev-master 可能会起作用，例如:

After while installing dependencies, I'm guessing that your package does not exist in a version just called dev, so it can't find it if you require it like that. Requiring dev-master would probably work, like:

{
    "name": "vendor/packagea",
    "minimum-stability": "dev",
    "require": {
        "vendor/packageb": "dev-master"
    }
}
