Go：如何运行file.go工作

[英]Go: How does go run file.go work

原文 2015-02-27 01:18:36 2 4 go

The commands go build and go install compile the files into binaries. 命令go build并运行go install将文件编译为二进制文件。 Does go run compile or interpret the file? go run编译还是解释文件？ I couldn't find explanations online and may have missed it. 我在网上找不到解释，可能错过了。 Appreciate pointers. 欣赏指针。 Thanks! 谢谢！

它或多或少相当于运行go build X.go -o /tmp/random-tmp-folder/exe && /tmp/random-tmp-folder/exe

The go run command compiles and runs a main package comprised of the .go files specified on the command line. go run命令编译并运行由命令行上指定的.go文件组成的主程序包。 The command is compiled to a temporary folder. 该命令被编译为临时文件夹。

The go build and go install examine the files in the directory to determine which .go files are included in the main package. go build和go install检查目录中的文件，以确定主包中包含哪些.go文件。

与在执行时创建和解释bytcode的java不同，go创建一个依赖于正在使用的机器的可执行文件，如c，c ++。

Command go run performs project's building under the hood (so yes it builds project) 命令go run在引擎盖下执行项目的构建（所以它是构建项目）
and with flag --work ( go run --work main.go ) you can see the location of temporary build files. 并使用flag --work（ go run --work main.go ），您可以看到临时构建文件的位置。

Also in official documentation ( go1.11 ) you can find: 同样在官方文档（ go1.11 ）中，您可以找到：

go run - compiles and runs the named main Go package. go run - 编译并运行命名的主Go包。

go build - compiles the packages named by the import paths, along with their dependencies, but it does not install the results. go build - 编译导入路径命名的包及其依赖项，但不安装结果。

go install - compiles and installs the packages named by the import paths. go install - 编译并安装导入路径命名的包。
