在Bower中指定版本号 [英] Specifying version numbers in Bower
问题描述
编写bower.json时,您可以在依赖项中指定版本号。
有时我看到有人写作
When writing bower.json you can specify version numbers in your dependencies. Sometimes I see people writing
{
...
"devDependencies" : {
"grunt" : "~0.3.13",
}
}
究竟是什么意思?为什么不写> = 0.3.13?
What exactly does the ~ mean? Why not write >=0.3.13?
这是某种最佳做法吗?
Is this some sort of best practice?
推荐答案
这是 semver 和符号与> = 0.3.13< 0.4.0
相同,它将匹配所有补丁
在 0.3.13
之后发布,但不包括 0.4.0
。这意味着您将获得错误修复(补丁
),但不是新功能(次要
)。不建议使用> = 0.3.13
,因为它会匹配任何超出某些时间点的内容。
It's semver and the notation is the same as >=0.3.13 <0.4.0
, which will match all patch
releases after and including 0.3.13
, but not 0.4.0
. This means you'll get bug fixes (patch
), but not new features (minor
). >=0.3.13
is not recommended as it will match anything above which will at some point break.
