+
+构建
+
+```shell
+git clone https://github.com/grafana/agent.git
+make agent-flow
+cd build
+```
+
+将以下配置保存到 config.river
+
+```r
+pyroscope.ebpf "instance" {
+	forward_to     = [pyroscope.write.endpoint.receiver]
+	targets_only   = false
+	default_target = {"service_name" = "ebpf_profile"}
+}
+
+pyroscope.write "endpoint" {
+	endpoint {
+		url = "http://localhost:4040"
+	}
+}
+```
+
+运行
+
+```shell
+sudo ./grafana-agent-flow run config.river
+/<path>/<to>/<pyroscope>/pyroscope
+# port for the HTTP(S) server used for data ingestion and web UI
+# address of the pyroscope server

+# port for the HTTP(S) server used for data ingestion and web UI
+# address of the pyroscope server
+# default http://localhost:4040
+```
+
+# yarn install package from local folder
+
+如果您想在本地文件夹中安装 yarn 包，您可以使用以下命令：
+
+首先，需要将本地文件夹打包成 tar 压缩包。您可以使用以下命令：
+
+```shell
+tar -zcvf package_name.tar.gz /path/to/local/folder
+```
+
+然后，您可以使用以下命令在项目根目录中安装本地 tar 包：
+
+```shell
+yarn add file:/path/to/package_name.tar.gz
+```
+
+这将解压 tar 包并将其安装到项目的 node_modules 文件夹中。
+
+请注意，安装本地 tar 包不是 yarn 的推荐方法，因此在生产环境中使用时请谨慎。
