Docker 构建映像返回错误：lambci/lambda：术语"lambci/lambda"未被识别为 cmdlet、函数、脚本文件的名称

Question

在windows 10 powershell中运行docker build命令时:

lambci/lambda: build-python3.7 -t rockar-data/lambda-layers .

我得到如下错误:

lambci/lambda: : The term 'lambci/lambda:' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again.

Answer 1

当有问题的字符串直接传递给powershell时，您将得到这样的消息，因为它应该知道如何处理。它接收到lambci/lambda:，但那不是可执行文件或有效命令的路径，所以它停止了。仔细看看你的脚本，看看它发生了什么，在某个地方，这一行单独出现，把事情搞砸了。
