gethでのSolidityセットアップ

Ethereum geth solidity

全ての場合についてのチュートリアル: 

http://solidity.readthedocs.io/en/develop/installing-solidity.html

 

[解決]ソースからbuildする場合:

http://block-chain.jp/tech/install-solidity-solc-on-mac/

インストールされていることを確認する方法:

$ which solc

パスが出てきたらインストールされている。

gethターミナルでのeth.getCompiler()メソッドはもう使われていないのでこちらを用いる。

 

 

homebrewでインストールする場合:

/usr/local/Homebrew/Library/Homebrew/utils/github.rb:210:in `raise_api_error': GitHub (GitHub::AuthenticationFailedError)
The GitHub credentials in the macOS keychain may be invalid.
Clear them with:
printf "protocol=https\nhost=github.com\n" | git credential-osxkeychain erase
Or create a personal access token:
https://github.com/settings/tokens/new?scopes=gist,public_repo&description=Homebrew
and then set the token as: export HOMEBREW_GITHUB_API_TOKEN="your_new_token"
