Could not find a version that satisfies the requirement tensorflow
提问by Martin W
I installed the latest version of Python (3.6.4 64-bit)and the latest version of PyCharm (2017.3.3 64-bit). Then I installed some modules in PyCharm (Numpy, Pandas, etc), but when I tried installing Tensorflow it didn't install, and I got the error message:
我安装了最新版本的 Python(3.6.4 64-bit)和最新版本的PyCharm (2017.3.3 64-bit). 然后我在 PyCharm 中安装了一些模块（Numpy、Pandas 等），但是当我尝试安装 Tensorflow 时它没有安装，我收到了错误消息：
Could not find a version that satisfies the requirement TensorFlow (from versions: ) No matching distribution found for TensorFlow.
找不到满足 TensorFlow 要求的版本（来自版本：）未找到与 TensorFlow 匹配的发行版。
Then I tried installing TensorFlow from the command prompt and I got the same error message. I did however successfully install tflearn.
然后我尝试从命令提示符安装 TensorFlow，但我收到了相同的错误消息。然而，我确实成功安装了 tflearn。
I also installed Python 2.7, but I got the same error message again. I googled the error and tried some of the things which were suggested to other people, but nothing worked (this included installing Flask).
我还安装了 Python 2.7，但我再次收到相同的错误消息。我用谷歌搜索错误并尝试了一些向其他人建议的东西，但没有任何效果（包括安装 Flask）。
How can I install Tensorflow? Thanks.

There are two important rules to install Tensorflow:
安装 Tensorflow 有两个重要规则：
You have to install Python x64. It doesn't work on 32b and it gives the same error as yours.
It doesn'tsupport the latest version of Python3 = 3.7.
您必须安装 Python x64。它在 32b 上不起作用，并且会出现与您相同的错误。
它不支持最新版本的 Python3 = 3.7。
For example, you can install Python3.6.2-64bitand it works like a Charm.
例如，您可以安装Python3.6.2-64bit，它就像一个 Charm。

Reportedly in the comment, it works in x64 version of Python3.8.
据报道，在评论中，它适用于 Python3.8 的 x64 版本。

if you are using anaconda, python 3.7 is installed by default, so you have to downgrade it to 3.6:
如果您使用的是anaconda，则默认安装 python 3.7，因此您必须将其降级到 3.6：
conda install python=3.6
conda 安装 python=3.6
then:
然后：
pip install tensorflow
