[英]Visual studio generated Dockerfile failing on npm install/dotnet publish step
我正在尝试创建一个 Angular/.NET Core webapp 并使用 Docker 提供它。 我为项目使用了 VS 模板及其“添加 Docker 支持”功能。
我能够将 npm 添加到 Dockerfile,但现在尝试安装 npm 时似乎仍然失败。

所以它似乎在 npm 安装任务上失败了,这反过来又导致整个构建失败。
这是 my.csproj 文件中的引用行。
<Target Name="PublishRunWebpack" AfterTargets="ComputeFilesToPublish">
<!-- As part of publishing, ensure the JS resources are freshly built in production mode -->
<Exec WorkingDirectory="$(SpaRoot)" Command="npm install" /> **// This is line 48**
<Exec WorkingDirectory="$(SpaRoot)" Command="npm run build -- --prod" />
<Exec WorkingDirectory="$(SpaRoot)" Command="npm run build:ssr -- --prod" Condition=" '$(BuildServerSideRenderer)' == 'true' " />
<!-- Include the newly-built files in the publish output -->
<ItemGroup>
<DistFiles Include="$(SpaRoot)dist\**; $(SpaRoot)dist-server\**" />

那么,是否存在某种目录问题,是否试图在错误的位置运行 npm 安装? 这是我的目录结构:
问题是你的 Dockerfile。 构建错误显示“npm:未找到”。 您需要在 Dockerfile 中添加一些额外的行,以便在容器中安装 nodejs。 如果您使用 Linux 容器,您应该添加下一行:
RUN curl -sL https://deb.nodesource.com/setup_10.x | bash -
RUN apt-get install -y nodejs
您的 Dockerfile 将类似于以下内容(将您的项目名称WebApplication38
替换为MeMa
):
