無法使用模擬從 SRPM 建構 RPM 包

我已經成功建構了 SRPM，在這一步之後，我嘗試從 SRPM 建構 RPM。以下是我建構 RPM 的目錄。源 RPM 位於以下目錄中。

$ ls
$ agent-ovs  genie  libopflex  libopflex-metadata  LICENSE  repo  sample  target

然後為了建構 RPM，我使用mockchain如下：

$ mockchain -m --nocheck -r epel-7-x86_64 -a file://`pwd`/repo/ \
 -l target libopflex/*.src.rpm genie/target/libmodelgbp/*.src.rpm \
 agent-ovs/*.src.rpm 

完成上述操作後，我會收到以下錯誤。當我檢查 URL 時，它們不存在。我該如何調試這個，我什至不知道從哪裡mockchain獲取這個 URL 和repomd.xml.

的yum儲存庫mockchain及其mock執行的命令將來自您指定的配置“epel-7-x86_64”和--addrepo=命令行上使用的任何標誌。配置通常位於/etc/mock/$CONFIG.cfg或在這種情況下，/etc/mock/epel-7-x86_64.cfg。

目前repomd.xml似乎來自建構機器上的本地記憶體，如有必要 yum，請將其刪除。yum clean all

要獲得對額外調試有用的更詳細的輸出，您應該能夠傳遞-m --verbose給mockchain.
