cosmos主网即将上线，对文档做了大量更新。特地翻译了一下，方便小伙伴们阅览, 之后会持续更新
第三章教程:
编译你的程序
Makefile
通过在根目录中编写包含常用命令的./Makefile来帮助用户编译应用程序：
注意：下面的Makefile包含一些与Cosmos SDK和Tendermint的Makefiles相同的命令。
DEP := $(shell command -v dep 2> /dev/null)
get_tools:
ifndef DEP
@echo "Installing dep"
go get -u -v github.com/golang/dep/cmd/dep
else
@echo "Dep is already installed..."
endif
get_vendor_deps:
@echo "--> Generating vendor directory via dep ensure"
@rm -rf .vendor-new
@dep ensure -v -vendor-only
update_vendor_deps:
@echo "--> Running dep ensure"
@rm -rf .vendor-new
@dep ensure -v -update
install:
go install ./cmd/nsd
go install ./cmd/nscli
Gopkg.toml
Golang有一些依赖管理工具。在本教程中，你将使用dep。dep使用仓库根目录中的Gopkg.toml文件来定义应用程序所需的依赖项。Cosmos SDK应用程序目前依赖于某些库的特定版本。以下列表包含所有必需的版本。首先使用下面的constraints和overrides项替换./Gopkg.toml文件的内容：
# Gopkg.toml example
#
# Refer to https://golang.github.io/dep/docs/Gopkg.toml.html
# for detailed Gopkg.toml documentation.
#
# required = ["github.com/user/thing/cmd/thing"]
# ignored = ["github.com/user/project/pkgX", "bitbucket.org/user/project/pkgA/pkgY"]
#
# [[constraint]]
# name = "github.com/user/project"
# version = "1.0.0"
#
# [[constraint]]
# name = "github.com/user/project2"
# branch = "dev"
# source = "github.com/myfork/project2"
#
# [[override]]
# name = "github.com/x/y"
# version = "2.4.0"
#
# [prune]
# non-go = false
# go-tests = true
# unused-packages = true
[[constraint]]
name = "github.com/cosmos/cosmos-sdk"
version = "v0.31.1"
[[override]]
name = "github.com/golang/protobuf"
version = "=1.1.0"
[[constraint]]
name = "github.com/spf13/cobra"
version = "~0.0.1"
[[constraint]]
name = "github.com/spf13/viper"
version = "~1.0.0"
[[override]]
name = "github.com/tendermint/go-amino"
version = "v0.14.1"
[[override]]
name = "github.com/tendermint/iavl"
version = "v0.12.0"
[[override]]
name = "github.com/tendermint/tendermint"
version = "v0.30.0-rc0"
[[override]]
name = "golang.org/x/crypto"
source = "https://github.com/tendermint/crypto"
revision = "3764759f34a542a3aef74d6b02e35be7ab893bba"
[[override]]
name = "github.com/otiai10/copy"
revision = "7e9a647135a142c2669943d4a4d29be015ce9392"
[[override]]
name = "github.com/btcsuite/btcd"
revision = "ed77733ec07dfc8a513741138419b8d9d3de9d2d"
[prune]
go-tests = true
unused-packages = true
注意：如果你再你自己的仓库重头开始编写项目，请确定在运行
dep ensure -v之前你已经导入路径github.com/cosmos/sdk-application-tutorial替换成你自己的整个仓库(可能是github.com/{.Username}/{.Project.Repo})。如果不这样做，则需要在再次运行dep ensure -v之前删除./vendor目录（rm -rf ./vendor）以及Gopkg.lock文件（rm Gopkg.lock）。
既然已经完成了这项管理工作，是时候安装dep以及项目依赖：
make get_tools
dep ensure -v
编译应用程序
# Update dependencies to match the constraints and overrides above
dep ensure -update -v
# Install the app into your $GOBIN
make install
# Now you should be able to run the following commands:
nsd help
nscli help
