“去建立”安装Go的新版本后变得非常缓慢 [英] "go build" became very slow after installing a new version of Go

问题描述

从Go 1.2.1升级到1.3（Windows 7 64位）后，go build执行时间从4周左右增加到45秒以上。除去版本更新没有其他更改。关闭病毒扫描程序似乎没有效果。任何线索？

解决方案

您可能每次都重新编译依赖项。试试去安装-a mypackage 来重建所有的依赖关系。

删除 $ GOPATH / pkg 也有助于确保您没有旧的目标文件。

使用 -x 标志构建将显示工具链是否查找不兼容的版本。

After upgrading from Go 1.2.1 to 1.3 (Windows 7 64 bit) "go build" execution time has increased from around 4 to over 45 seconds. There were no other changes except the go version update. Switching off the virus scanner seems to have no effect. Any clues?

解决方案

You probably have dependencies that are being recompiled each time. Try go install -a mypackage to rebuild all dependencies.

Removing $GOPATH/pkg also helps to ensure you don't have old object files around.

Building with the -x flag will show you if the toolchain is finding incompatible versions.
