尝试从 `opencensus.ext.stackdriver` 安装和导入 `stats_exporter` 时进行故障排除

Question

我正在尝试使用以下指南从 opencensus.ext.stackdriver 安装和使用 stats_exporter：opencensus-ext-stackdriver

通过 pip 安装后：

pip install opencensus-ext-stackdriver

我正在尝试导入它并且：

from opencensus.ext.stackdriver import stats_exporter as stackdriver
ImportError: cannot import name 'stats_exporter' from 'opencensus.ext.stackdriver'

当比较 Git 仓库和我的本地 venv/lib/python3.7/site-packages/... 时，pip 版本似乎与 Github 不兼容，所以我尝试通过克隆来安装它，并使用 setup.py

pip install ../opencensus-python/contrib/opencensus-ext-stackdriver/dist/opencensus-ext-stackdriver-0.2.dev0.tar.gz

这给了我以下错误：

(venv) Yehoshaphats-MacBook-Pro:present-value yehoshaphatschellekens$ pip install ../opencensus-python/contrib/opencensus-ext-stackdriver/dist/opencensus-ext-stackdriver-0.2.dev0.tar.gz 
Processing /Users/yehoshaphatschellekens/opencensus-python/contrib/opencensus-ext-stackdriver/dist/opencensus-ext-stackdriver-0.2.dev0.tar.gz
    Complete output from command python setup.py egg_info:
    Traceback (most recent call last):

      File "/private/var/folders/s2/y6vcdc1105s8xlpb12slr9z00000gn/T/pip-req-build-7m1ibdpd/setup.py", line 17, in <module>
        from version import __version__
    ModuleNotFoundError: No module named 'version'

    ----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in /private/var/folders/s2/y6vcdc1105s8xlpb12slr9z00000gn/T/pip-req-build-7m1ibdpd/

这种类型的类似错误表明我需要升级 setuptools，也试过了 :(

表明它可能与我正在使用 python3 的事实有关，尽管我确实需要在我的计算机上安装此软件包，但 version 无法完成python3 venv.

任何关于这个问题的帮助都会很棒！

Answer 1

试试这个：

#!/usr/bin/env python

import os

from opencensus.common.transports.async_ import AsyncTransport

from opencensus.ext.stackdriver import trace_exporter as stackdriver_exporter

from opencensus.trace import tracer as tracer_module
from opencensus.stats import stats as stats_module


def main():
    sde = stackdriver_exporter.StackdriverExporter(
                project_id=os.environ.get("PROJECT_ID"),
                transport=AsyncTransport)

    tracer = tracer_module.Tracer(exporter=sde)
    with tracer.span(name='doingWork') as span:
        for i in range(10):
            continue


if __name__ == "__main__":
    main()

和

grpcio==1.19.0
opencensus==0.3.1
opencensus-ext-stackdriver==0.1.1

NB OpenCensus 库也需要 gRPC。

您将需要：

一个 GCP 项目及其项目 ID (${PROJECT_ID})
具有 roles/cloudtrace.agent 及其密钥的服务帐户。

然后：

virtualenv venv
source venv/bin/activate

export PROJECT_ID=[[YOUR-PROJECT-ID]]
export GOOGLE_APPLICATION_CREDENTIALS=/path/to/your/key.json

pip3 install --requirement requirements.txt
python3 stackdriver.py
