从`stats_exporter`安装和导入`opencensus.ext.stackdriver`时遇到的问题

Question

我试图使用以下指南从stats_exporter安装和使用opencensus.ext.stackdriver：开放-下栈驱动器

在通过pip安装它之后：

pip install opencensus-ext-stackdriver

我试着进口它，并：

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

当比较Git和我的本地venv/lib/python3.7/site-packages/...时，似乎pip版本与Github不兼容，所以我尝试通过克隆和使用setup.py来安装它。

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:

        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/

类似的这种类型的错误表明我需要升级setuptools，也尝试过:(

这个职位表示，这可能与我使用的python3有关，虽然我确实需要在python3上安装这个软件包，但它与version并不完全。

在这个问题上的任何帮助都将是伟大的！

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。

你需要：

• GCP项目及其项目ID (${PROJECT_ID})
• 带有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
