安裝

我們選擇最簡單的npm安裝的方式,在這裡加上-g進行全域性安裝。

xiaoyu@LIXIAOYUdeMBP.com➤ npm install -g solc
npm ERR! code EINTEGRITY
npm ERR! sha1-gJpbElfHwgDhGoQbN36uwnRphTk= integrity checksum failed when using sha1

報錯了。。。。

再來一次。。。。

xiaoyu@LIXIAOYUdeMBP.com➤ npm install -g solc
/usr/local/bin/solcjs -> /usr/local 
/lib/node_modules/solc/solcjs
+ solc@0.4.16
added 65 packages in 39.97s

成功了，並且得到當前的版本號為0.4.16

IDE

Remix是一個線上的IDE,來實現對Solidity的程式碼編寫和執行。

關聯到本地環境

點選左上角的第三個圖示，將IDE連線到本地的執行環境。

此功能允許與Remix的檔案系統進行互動。連線完成後，共享資料夾將在本地主機下的檔案瀏覽器中可用
Remixd必須首先在本地計算機上執行。有關詳細資訊，請參閱http://remix.readthedocs.io/en/latest/tutorial_remixd_filesystem.html。
接受此對話方塊將啟動https://remix.ethereum.org/和本地檔案系統之間的會話ws：//127.0.0.1：65520
請確保您的系統足夠安全（埠65520既不開啟也不轉發）。
將更新連線狀態。
此功能仍然是alpha，我們建議保留共享資料夾的副本。

下面安裝remixd

[email protected].com➤ npm install -g remixd
/usr/local/bin/remixd -> /usr/local/lib/node_modules/remixd/src/main.js

> websocket@1.0.24 install /usr/local/lib/node_modules/remixd/node_modules/websocket
> (node-gyp rebuild 2> builderror.log) || (exit 0)

  CXX(target) Release/obj.target/bufferutil/src/bufferutil.o
  SOLINK_MODULE(target) Release/bufferutil.node
  CXX(target) Release/obj.target/validation/src/validation.o
  SOLINK_MODULE(target) Release/validation.node
+ remixd@0.1.2
added 18 packages in 18.37s

如何使用

然後remixd -S <專案的絕對路徑>將啟動Remixd並共享給定的資料夾。
使用Remix IDE和Remixd之間的Websocket連線來共享該資料夾。
確保執行Remix的使用者對該資料夾具有讀/寫許可權。

Remixd可以為可以訪問本地主機上的TCP埠65520的任何應用程式提供對給定資料夾的完全讀寫訪問許可權
