无法安装 playwright：无法使用 Playwright 找到项目。确保项目或解决方案存在于

Question

我正在尝试在我的部署目标机器上安装 playwright，以便运行 UI 测试。

# Install the CLI once.
dotnet tool install --global Microsoft.Playwright.CLI

playwright install

然而，当使用包括 playwright 安装在内的 playwright CLI 时，我得到：

Couldn't find project using Playwright. Ensure a project or a solution exists in C:\users\myuser, or provide another path using -p.

如何在虚拟机上安装 playwright？

编辑：

遗憾的是，playwright 的 .NET nuget 包设计得不是很好。虽然 API 很棒，但部署却是噩梦。

不仅您无法在部署服务器上使用 CLI 安装浏览器，而且该软件包还会为您的项目以及所有引用它的项目增加 3 倍的 NodeJS 运行时间 (200MB)。

阻止这些文件被发布是很重要的，而且您的构建工件很容易增长到每个构建 1GB！

您无法配置 NodeJS 或编剧本身的路径。

Answer 1

您需要在包含csproj的文件夹中执行playwright install或使用-p指定项目文件

# Create project
dotnet new console -n PlaywrightDemo
cd PlaywrightDemo

# Install dependencies, build project and download necessary browsers.
dotnet add package Microsoft.Playwright
dotnet build
playwright install

有关详细信息，请参阅文档：https://playwright.dev/dotnet/docs/intro#first-project

您还可以使用代码安装浏览器：

using Microsoft.Playwright;

var exitCode = Microsoft.Playwright.Program.Main(new[] { "install" });
