这里是完整的error message .

我见过其他类似的案例，但它们并没有解决我的问题。我试过:

Pip install error in Mac OS(error: command '/usr/bin/clang' failed with exit status 1)

尝试在之前添加这些 env var

GRPC_PYTHON_BUILD_SYSTEM_OPENSSL=true GRPC_PYTHON_BUILD_SYSTEM_ZLIB=true pip install google-cloud-pubsub==2.1.0

如果它不起作用，您可以尝试使用 virtualenv:

pip install virtualenv
virtualenv my-test-env
source my-test-env/bin/activate
my-test-env/bin/pip install google-cloud-pubsub==2.1.0

因为写在github :

Install this library in a virtualenv using pip. virtualenv is a tool to create isolated Python environments. The basic problem it addresses is one of dependencies and versions, and indirectly permissions.

With virtualenv, it's possible to install this library without needing system install permissions, and without clashing with the installed system dependencies.
