將 Geth 從 1.6 降級到 1.59 以將 solc 集成到 Geth

我在 ropsten testnt 上有一個不想繼續開發但繼續執行的項目。由於他們在 v1.6 上從 Geth 中取出了 solc，因此我得到錯誤方法 eth_compilesolidity 不存在。有沒有簡單的方法解決它？如果我將 Geth 降級到 v1.5，我的項目是否可以在不需要更改任何內容的情況下執行，我是否需要刪除我已經擁有的 testnet 區塊鏈？另外在Linux上將geth降級到v1.5的正確方法是什麼？

當您將二進製文件降級到 1.5.9 時，您的項目應該沒問題。雖然，我建議之前進行備份。

您可以從 go-ethereum 項目https://github.com/ethereum/go-ethereum/releases/tag/v1.5.9的發布頁面獲取 1.5.9 的原始碼並為您的系統建構。

更新：

我在 1.6.1 上同步了完整的 Ropsten 區塊鏈，並將二進製文件降級為從原始碼建構的 1.5.9。之後，我啟動了客戶端。客戶正在工作。
