由于依赖项冲突 (Python 3)，无法在我们的 python 应用程序 (Google Cloud Platform) 中安装 google-api-core 包

Question

当我尝试安装 Google Core API 包时，该包的每个不同版本总是会出现错误。该应用程序在 Python 3 中运行，我得到以下日志：

The user requested google-api-core==1.21.0
    google-cloud-core 1.4.3 depends on google-api-core<2.0.0dev and >=1.19.0
    google-api-core[grpc,grpcgcp] 1.29.0 depends on google-api-core 1.29.0

ERROR: Cannot install -r requirements.txt (line 52) and google-api-core[grpc,grpcgcp]==1.14.0 because these package versions have conflicting dependencies.
ERROR: ResolutionImpossible: for help visit https://pip.pypa.io/en/latest/user_guide/#fixing-conflicting-dependencies

The command '/bin/sh -c pip3 install -r requirements.txt' returned a non-zero code: 1
ERROR
ERROR: build step 0 "gcr.io/cloud-builders/docker" failed: step exited with non-zero status: 1

我们想在 Google Cloud Platform 上安装这个包。有人可以帮我解决冲突的依赖问题吗？

我们尝试了以下软件包，但没有一个起作用。

#google-api-core==1.29.0
#google-api-core[grpc,grpcgcp]==1.14.0
#google-api-core==1.23.0
# google-api-core==1.19.0
# google-api-python-client==1.9.3
# google-auth==1.30.0
# google-auth-httplib2==0.0.4
# google-auth-oauthlib==0.4.1
# google-cloud==0.34.0
# google-cloud-bigquery==1.25.0
# google-cloud-bigquery-storage==2.0.1
# google-cloud-bigtable==1.2.1
# google-cloud-core #==1.4.3
# google-cloud-datastore==1.12.0
# google-cloud-language==2.0.0
# google-cloud-logging==1.15.0
# google-cloud-pubsub==2.1.0
# google-cloud-resource-manager==0.30.2
# google-cloud-scheduler==2.2.0
# google-cloud-secret-manager==2.0.0
# google-cloud-spanner==1.19.1

# google-cloud==0.34.0
# google-auth==1.22.1
#grpc-google-iam-v1==0.12.3
#grpcio==1.29.0
# google-resumable-media

所有其他相关软件包版本如下，并且它们正在工作：

google-api-core==1.21.0
google-api-python-client==1.6.7
google-auth==1.30.0
google-auth-httplib2==0.0.4

将这些步骤写入您的requirements.txt文件中：

google-api-core==1.29.0
google-api-core[grpc,grpcgcp]==1.14.0
google-api-python-client==1.9.3
google-auth==1.30.0
google-auth-httplib2==0.0.4
google-auth-oauthlib==0.4.1
google-cloud==0.34.0
google-cloud-bigquery==1.25.0
google-cloud-bigquery-storage==2.0.1
google-cloud-bigtable==1.2.1
google-cloud-core ==1.4.3
google-cloud-datastore==1.12.0
google-cloud-language==2.0.0
google-cloud-logging==1.15.0
google-cloud-pubsub==2.1.0
google-cloud-resource-manager==0.30.2
google-cloud-scheduler==2.2.0
google-cloud-secret-manager==2.0.0
google-cloud-spanner==1.19.1
google-cloud-storage==1.29.0
google-cloud==0.34.0
grpc-google-iam-v1==0.12.3
grpcio==1.29.0
google-resumable-media

创建虚拟环境，然后安装依赖项。执行此操作的步骤是：

1. python3 -m venv env

2. source env/bin/activate

3. pip list

4. pip install -r requirements.txt
