python-2.7 - 无法使用pip install grpcio安装grpcio

Question

我在Windows机器上使用pip install grpcio安装grpcio时遇到错误，我在这里读到https://github.com/grpc/grpc/issues/17829，这可能是由于setuptools版本中的错误引起的。我将我的setuptools升级到了最新版本，即41.0.1。仍然出现相同的构建错误。其他任何软件包都不会发生。我尝试在笔记本电脑上重新安装pip和python。我附上我的错误

Answer 1

一，升级点子

pip3 install --upgrade pip

然后，更新设置工具:

python3 -m pip install --upgrade setuptools

最后，使用安装 grpcio:

pip3 install --no-cache-dir  --force-reinstall -Iv grpcio==<version_number>
