Question

我有一个项目依赖xxx（xxx具有到本地c库'a'的链接），我想介绍一个新的依赖项yyy，它也具有指向'a'（某些库的不同版本）的链接。当我运行“货物更新”时，它成为事实并记录为“无法为xxx选择一个版本。...包xxx链接到本机库a，但与也链接到a的先前软件包：包yyy'

我已经阅读了一些文档，通过在cargo.toml和build.rs中添加一些代码来使链接具有全局性似乎是可行的，但是我不确定该怎么做，并且两个不同的依赖项可以具有相同的链接吗？ / p>

error: failed to select a version for `parity-rocksdb-sys`.
    ... required by package `parity-rocksdb v0.5.0`
    ... which is depended on by `kvdb-rocksdb v0.1.4`
    ... which is depended on by `storage v0.0.1 (/Users/chenrui/Desktop/blockchain/WendingWorkStation/ipfs/filesys-rust/runtime/storage)`
    ... which is depended on by `beacon v0.0.1 (/Users/chenrui/Desktop/blockchain/WendingWorkStation/ipfs/filesys-rust/chain/beacon)`

versions that meet the requirements `^0.5` are: 0.5.5, 0.5.4, 0.5.3, 0.5.2, 0.5.1, 0.5.0

the package `parity-rocksdb-sys` links to the native library `rocksdb`, but it conflicts with a previous package which links to `rocksdb` as well:
package `librocksdb-sys v5.17.2`
    ... which is depended on by `rocksdb v0.12.0`
    ... which is depended on by `filecoin-proofs v0.1.0 (https://github.com/idotial/rust-fil-proofs.git#53676171)`
    ... which is depended on by `filesys v0.1.0 (/Users/chenrui/Desktop/blockchain/WendingWorkStation/ipfs/filesys-rust)`

failed to select a version for `parity-rocksdb-sys` which could resolve this conflict

fix this error, and finish cargo update

软件包XXX链接到本机库YYY，但与先前的软件包也链接到YYY冲突：软件包ZZZ
