使用multer和multer存储的依赖问题

Question

首先，为了托管目的，我想把我的所有文件都推到heroku，在这里我不能在heroku上安装multer和multer-gridfs-存储的依赖，所以我不能在heroku上托管我的网站。

-lts.1在multer@"^1.4.5-lts.1"上的后缀导致它不被来自multer-gridfs-storage@5.0.2的对等版本约束^1.4.2所匹配。根据npm信号计算器的说法，满足这个版本约束的Multer的最新版本是1.4.4。

考虑到似乎是1.x开发行兼容的延续。和穆特存在于国家预防机制生态系统中，我认为这是穆特项目中的一个缺陷。它的版本号应该满足NPM对术语的理解。

最简单的解决方案是将您对Multer的直接依赖从版本^1.4.5-lts.1减少到版本1.4.4，这满足了来自GridFS存储的对等依赖。希望您不依赖于更新版本中的任何特性或bug修复。

我已经提交了一个针对穆特计划的错误，这表明它的LTS版本约束仍然与拼写器兼容，前提是1.4.5-lts.1版本实际上应该与版本1.4.4和更早版本兼容。

我在术语或国家预防机制方面的知识不足，不足以知道这种实施是否实际上是正确的。重要的是，穆特项目和国家预防机制的实施似乎有冲突。

我相信-lts.1后缀被认为是预录 (也就是说，1.4.4-lts.1将出现在1.4.4之前)。符号器计算器似乎是一致的:使用版本约束的>=1.4.2 <=1.4.4-lts.1匹配1.4.2、1.4.3和1.4.4-lts.1，但不匹配1.4.4。
