go - 如何更改 IBM-Cloud cloudfoundry golang 应用程序版本？

Question

当我运行命令 ibmcloud target --cf && ibmcloud cf restart appname ，它显示错误，似乎golang版本无效，但我无法更改它以指定没有root权限的版本，或者它可以通过创建容器例如是旧版本？

您的环境似乎配置为使用较旧的 Golang 版本。并且在已安装的可用构建包中找不到该版本。您可以查看 list 和其他配置文件设置的版本。或者您可以使用 manifest attribute 切换到不同的构建包。或命令选项(参见 ibmcloud cf push --help 列出 buildpack 选项)。
