英文:
Gomobile toolchain out of date, only in Android Studio
问题
我正在使用最新的gomobile、Go和Android Studio版本。
当我在终端中运行gradle任务时，它们按预期工作并构建正确的二进制文件，但是在Android Studio中，我收到一个错误：
bin/gomobile: 工具链过时，请运行`gomobile init`
当然，我已经多次重新运行了gomobile init，但没有任何变化。我的假设是Android Studio正在使用一些我无法识别的配置。
我知道这是一个比较特殊的问题，但如果有人能指点我正确的方向，那将非常有帮助。
简而言之：./gradlew myproj:bind在终端中正常工作，在Android Studio中失败。
英文:
I am working with the latest gomobile, Go, and Android Studio builds.
When I run the gradle tasks from the terminal they work as expected and build the correct binaries, however from within Android Studio I receive an error:
bin/gomobile: toolchain out of date, run `gomobile init`
Of course I have re run gomobile init many times and no change. My assumption is that Android Studio is using some config that I can not identify.
I appreciate this is a somewhat edge case question, but if anyone can point me in the right direction it would be helpful.
TLDR; ./gradlew myproj:bind works fine in terminal, fails in Android Studio.

我已经找到了这个问题的根源，以防其他人也遇到同样的问题；
-
对我来说，似乎 Gradle 插件没有正确识别 GO bin 的位置。相反，它使用以下方式查找 gobin；
gobin, err := exec.LookPath("go")
我安装了多个 Go 版本（出于各种原因），所以我强制指定 gobin 失败了。为了发现这个问题，我在 env.go 文件中添加了调试日志。总的来说，当尝试调试时，该文件上的日志记录并不是最清晰的。
英文:
I have gotten to the bottom of this in case anyone else has the issue;
-
It appears, at least for me, the Gradle plugin wasn't respecting the location of the GO bin. Instead it looks up the gobin using;
gobin, err := exec.LookPath("go")
I have a number of Go versions installed (for various reasons) so my forcing the gobin was failing. To discover this I have added debug logs to the env.go file. In general the logging on the file is not the most clear when attempting to debug.

这似乎是一个gomobile的错误信息，出现在cmd/gomobile/env.go#L69-L83中：
// 查找gomobilepath。
gopath := goEnv("GOPATH")
for _, p := range filepath.SplitList(gopath) {
gomobilepath = filepath.Join(p, "pkg", "gomobile")
if _, err := os.Stat(gomobilepath); buildN || err == nil {
break
}
}
verpath := filepath.Join(gomobilepath, "version")
installedVersion, err := ioutil.ReadFile(verpath)
if !bytes.Equal(installedVersion, version) {
return nil, errors.New("toolchain out of date, run `gomobile init`")
}
因此，请在本地会话和Android Studio会话之间仔细检查GOPATH的值。
例如，查看这个旧的（2015年）线程，看看其中的评论是否仍然适用。
英文:
This seems to be a gomobile error message, seen in cmd/gomobile/env.go#L69-L83:
// Find gomobilepath.
gopath := goEnv("GOPATH")
for _, p := range filepath.SplitList(gopath) {
gomobilepath = filepath.Join(p, "pkg", "gomobile")
if _, err := os.Stat(gomobilepath); buildN || err == nil {
break
}
}
verpath := filepath.Join(gomobilepath, "version")
installedVersion, err := ioutil.ReadFile(verpath)
if !bytes.Equal(installedVersion, version) {
return nil, errors.New("toolchain out of date, run `gomobile init`")
}
So double-check the value of GOPATH between your local session and your Android Studio session.
