从Xcode 8中的macOS应用程序中运行 cargo 时出现了一个奇怪的错误：

Eonil$ cargo clean
[~/Temp/repotest1/ag] (master)
Eonil$ cargo build
   Compiling ag v0.1.0 (file:///Users/Eonil/Temp/repotest1/ag)

为什么我会收到此错误以及如何解决此问题？

  • cargo 0.15.0-nightly (298a012 2016-12-20)

  • rustc 1.14.0 (e8a012324 2016-12-16)

rust rust-cargo

    环境变量 MallocNanoZone 设置为 1 . 删除它或将其设置为 0 ，问题神奇地消失了 .

    我不知道为什么会这样 . 就我而言，使用 NSTask 在Xcode调试上下文中运行货物时发生错误 . Xcode自动设置 MallocNanoZone=1 ，它改变了一些对 cargo 执行不友好的内存管理行为 .
