未能安装状态为500的链代码

Question

我正在运行hyperledger fabric 2.2.0测试网络。它运行了2-3天，但现在当我尝试安装链代码(任何(时，打包后失败了。下面是我得到的错误-

错误：链代码安装失败，状态为：500-未能调用"InstallChaincode"的支持实现：无法生成链代码：docker生成失败：docker映像生成失败：docker生成失败：生成返回的错误：1"无法初始化/home/chaincode/上的生成缓存。cache/go-build:mkdir/home/cchancode/。cache:权限被拒绝

我没有做任何改变，一直工作到昨天都很好。如果它需要制作目录"/home/chaincode/.cache"；然后它在过去的3天里是如何工作的，因为它没有所需的许可。

我在家里手动创建了一个目录"chaincode"，并将其权限更改为777，但仍然存在相同的错误。

感谢所有的帮助。谢谢

我昨天也遇到了类似的问题。

我已经将链代码部署到一个AWS实例中。链代码的早期版本正在运行。我有两个AWS实例的对等体。

昨天，当我试图向对等端安装一个新的链代码时，它显示了以下错误。

为了暂时解决这个问题，我们备份了对等端，couchdb，并将对等端移动到一个新的AWS实例，并进行了适当的更改。现在，链代码正在新的AWS实例中运行。

注意：两个AWS实例的dpkg-打印架构显示amd64为cpu架构。
