【以太坊】Mac安装abigen遇到的坑

安装devtools报错

想要开发以太坊，就需要开发智能合约，需要安装aligen，Mac版本需要通过安装devtools的方式安装abigen

$ make devtools
env GOBIN= go install golang.org/x/tools/cmd/stringer@latest
env GOBIN= go install github.com/kevinburke/go-bindata/go-bindata@latest
go: downloading github.com/kevinburke/go-bindata v3.11.0

go install github.com/kevinburke/go-bindata/go-bindata@latest: zip for github.com/kevinburke/go-bindata@v3.11.0 has unexpected file github.com/kevinburke/go-bindata@v0.0.0-20180804232615-06af60a4461b/.gitignore

这个原因是和镜像云有关系，导致不能安装go-bindata，我之前使用的是阿里云的镜像库，切换成官方的镜像，重新安装一下

$ go env -w  GOPROXY=https://goproxy.io,direct
$ make devtools
env GOBIN= go install golang.org/x/tools/cmd/stringer@latest
env GOBIN= go install github.com/kevinburke/go-bindata/go-bindata@latest
go: downloading github.com/kevinburke/go-bindata v3.22.0+incompatible
env GOBIN= go install github.com/fjl/gencodec@latest

go: downloading golang.org/x/tools v0.0.0-20191126055441-b0650ceb63d9
env GOBIN= go install github.com/golang/protobuf/protoc-gen-go@latest
go: downloading github.com/golang/protobuf v1.5.2
go: downloading google.golang.org/protobuf v1.26.0
env GOBIN= go install ./cmd/abigen
# gopkg.in/olebedev/go-duktape.v3
In file included from _cgo_export.c:4:
debugger.go:23:13: warning: unused function '_duk_debugger_attach' [-Wunused-function]
Please install solc
Please install protoc

看到最后两句意思应该是缺少了solc和protoc

$ npm install -g solc-cli solc protoc

$ brew install protoc-gen-go

重试下

$ make devtools
In file included from _cgo_export.c:4:
debugger.go:23:13: warning: unused function '_duk_debugger_attach' [-Wunused-function]

还是有报错，

没办法，只能换个思路，

后来通过官网发现，有现成的build工具 https://geth.ethereum.org/downloads/

所以又重新下载解压了一次
