[英]Does npm honour newer prerelease versions in semver?
In my app, I have users install dependencies by running npm install
-- bog standard behaviour. 在我的应用程序中,我让用户通过运行
npm install
-bog标准行为来安装依赖项。
However, I have one package that changes frequently, and in an effort to not end up with a ridiculously large version number like 0.1.12324
, I stumbled upon the concept of pre-releases. 但是,我有一个经常更改的软件包,并且为了最终没有像
0.1.12324
这样可笑的大版本号,我偶然发现了预发布的概念。
How does npm treat prerelease numbers when running npm install
? 在运行
npm install
时, npm install
如何处理预发布数字?
Assuming my package packageA
has a version number of 0.1.1-r1234
, and my users have a dependency semver of ~0.1.1
: 假设我的包
packageA
的版本号为0.1.1-r1234
,我的用户的依赖关系semver为~0.1.1
:
I know that a new user without packageA
installed will automatically have that version ( 0.1.1-r1234
) installed. 我知道没有安装
packageA
的新用户将自动安装该版本( 0.1.1-r1234
)。
What if someone already has packageA
installed, of version 0.1.1-r1233
? 如果某人已经安装了
packageA
,版本为0.1.1-r1233
怎么0.1.1-r1233
? Does npm install
know to install the newer pre-release? npm install
是否知道安装较新的预发行版?
I seemed to have answered my own question. 我好像回答了自己的问题。 From the main page at semver.org :
从semver.org的主页面 :
Precedence for two pre-release versions with the same major, minor, and patch version MUST be determined by comparing each dot separated identifier from left to right until a difference is found as follows: identifiers consisting of only digits are compared numerically and identifiers with letters or hyphens are compared lexically in ASCII sort order.
具有相同主要版本,次要版本和补丁版本的两个预发行版本的优先级必须通过从左到右比较每个点分隔标识符来确定,直到找到差异如下:仅由数字组成的标识符在数字上与标识符与字母进行比较或者连字符以ASCII排序顺序进行词汇比较。 Numeric identifiers always have lower precedence than non-numeric identifiers.
数字标识符的优先级始终低于非数字标识符。 A larger set of pre-release fields has a higher precedence than a smaller set, if all of the preceding identifiers are equal.
如果所有前述标识符相等,则更大的预发布字段集合具有比较小集合更高的优先级。 Example: 1.0.0-alpha < 1.0.0-alpha.1 < 1.0.0-alpha.beta < 1.0.0-beta < 1.0.0-beta.2 < 1.0.0-beta.11 < 1.0.0-rc.1 < 1.0.0.
示例:1.0.0-alpha <1.0.0-alpha.1 <1.0.0-alpha.beta <1.0.0-beta <1.0.0-beta.2 <1.0.0-beta.11 <1.0.0- rc.1 <1.0.0。
