彈出作業系統錯誤：和rrno2和rrn這2Errno 2沒有相應的文件和目錄

嘗試時：

$populus compile

得到：

OSError: [Errno 2] No such file or directory

試過：

嘗試按照此處所述安裝缺少的依賴項並安裝了solidity編譯器- 結果相同。在 sudo 或 virtualenv 下的結果相同。populus init按預期工作。

安裝一些其他工具（如 EthereumJS testrpc）後，問題自行解決了。我猜是我的電腦上沒有正確安裝的 solc 編譯器。

用於從原始碼建構solidity 編譯器，然後將其安裝為npm 包，這更容易。

所以，如果你有同樣的問題。嘗試檢查solc命令是否有效。

錯誤是說您沒有目錄：

/home/petr/Projects/populus-tests/contracts

是這樣嗎？如果是，則創建它並將您的契約源文件複製到其中。
