linux - 我有 AWS SAM local 0.2.11，但我无法将其升级到 0.3.0。升级没有发生

Question

我正在运行 Ubuntu Desktop 18.04 LTS。

/home/ashu# sam --version
A newer version of the AWS SAM CLI is available!
Your version:   0.2.11
Latest version: 0.3.0
See https://github.com/awslabs/aws-sam-local for upgrade instructions

sam version 0.2.11

但是当我尝试按照说明进行升级时 here 我没有获得任何成功...

这个命令: npm uninstall -g aws-sam-local

doesn't un-install the older version

在此之后 - 后续命令:

pip install --user --upgrade aws-sam-cli

没有升级它。

sam version 0.2.11

Answer 1

仔细检查您是否遵循了安装说明 in the SAM documentation

然而，npm 似乎经常无法删除 sam 可执行文件。运行 which sam，删除或移动该文件(例如 rm sam)，然后重新启动您的 shell。然后 linux 将在您的 PATH 中找到正确的 sam 如果您已按照安装说明进行操作。

(如您所述，问题的根源是 NPM 问题，但该讨论超出了本问题的范围。)
