requirements.txt代码等于（〜=）vs tilde大于（〜>）

[英]requirements.txt tilde equals (~=) vs tilde greater-than (~>)

原文 2019-02-13 19:57:18 7 1 python/ requirements.txt

According to this question and it's links to elsewhere, I learned that ~= VN is the same as >= VN, == V.* 根据这个问题以及它与其他地方的联系，我了解到~= VN与>= VN, == V.*

For a given release identifier VN , the compatible release clause is approximately equivalent to the pair of comparison clauses: 对于给定的发布标识符VN，兼容发布子句大致等同于一对比较子句：

>= VN, == V.*

PEP 440 Compatible Release PEP 440兼容版本

But what does ~> VN mean? 但是什么~> VN是什么意思？ Does it just mean > VN, == V.* , indicating that version VN would not satisfy the requirement, but that V.(N+1) would? 它只是意味着> VN, == V.* ，表明版本VN不满足要求，但是V.(N+1)会吗？

Note: I haven't seen anywhere that this notation has been used, but GitHub recently sent a security alert saying to update one requirements.txt to use this syntax. 注意：我没有看到任何地方使用过这种表示法，但GitHub最近发送了一个安全警报，说更新一个requirements.txt以使用这种语法。

This ~> is not a valid requirement specifier in Python. 这个~>不是Python中的有效需求说明符。

The security alert must be talking about another language - perhaps it was a Gemfile (Ruby)? 安全警报一定是在谈论另一种语言 - 也许它是一个Gemfile（Ruby）？
