由于找不到 git，Docker 构建失败

Question

我正在包含requirement.txt 和所有内容的目录中运行以下命令。

sudo docker build -t flask-container .

但我收到这个错误。

Running command git clone -q https://github.com/pysentimiento/pysentimiento /tmp/pip-install-5crn_ko5/pysentimiento_472d6d991b204e42acc02194d0e3b813

ERROR: Cannot find command 'git' - do you have 'git' installed and in your PATH?

Dockerfile -----------------

由于未找到 git，这意味着它要么在映像构建期间没有安装，要么在运行它时在容器中找不到。

您可以使用以下选项之一安装 git（取决于您的发行版）：

• Ubuntu/Debian：apt-get install -y git
• 高山：apk add git
• 森托斯：yum -y install git

安装前请确保升级软件包列表。

或者，如果 git 已安装，请确保它位于 PATH 中，执行到容器中并回显 PATH，然后检查它是否包含安装 git 的位置。

根据提供的文件，您需要将以下内容添加到 Dockerfile 中。

RUN apk update && apk add git
