不用翻墙解决Go升级1.4后liteIDE找不到godoc的问题

Go升级到1.4之后，liteIDE启动会提示：

11:29:27 GolangDoc: Could not find godoc, (hint: is godoc installed?)

原因是：

Changes to package source layout

In the main Go source repository, the source code for the packages was kept inthe directory src/pkg, which made sense but differed fromother repositories, including the Go subrepositories.In Go 1.4, the pkg level of the source tree is now gone, so for examplethe fmt package's source, once kept indirectory src/pkg/fmt, now lives one level higher in src/fmt.

Updating: Tools like godoc that discover source codeneed to know about the new location. All tools and services maintained by the Go teamhave been updated. 

解决办法：

1.

翻墙  go get -v -u golang.org/x/tools/cmd/godoc

不翻墙 git clone https://github.com/golang/tools $GOPATH/src/golang.org/x/tools 

2.

go build $GOPATH/src/golang.org/x/tools/cmd/godoc
mv $GOPATH/src/golang.org/x/tools/cmd/godoc/godoc $GOPATH/bin/
