无法安装PIP密码学 [英] PIP Cryptography Failing to Install

问题描述

这个问题有很多答案，涉及很多不同的场景，但是我还没有找到解决同一问题的解决方案.当我尝试安装 pip安装密码学时，我得到:

There are a quite a few answers to this question covering a ton of different scenarios but I've yet to find a solution to the self-same issue. When I try to install pip install cryptography I get:

1. 我正在Windows 10上的PyCharm 2019.2.5中运行虚拟环境.
2. 我已经从 https://slproweb.com/products/Win32OpenSSL.html，然后选择 最新的32位版本(我初次尝试安装了64位，但在其他地方阅读过，有人对此有问题，因此转换为32位)
3. 我已将LIB和INCLUDE位置更新为相关的../openssl/include和../openssl/lib位置，并尝试重新运行 pip install ，但我仍然得到相同的消息.我已经在PyCharm和标准CMD提示符下的终端中完成了此操作.
4. 我正在运行19.0.3版的PIP

1. I am running a virtual environment within PyCharm 2019.2.5 on a Windows 10.
2. I have installed OpenSSL from https://slproweb.com/products/Win32OpenSSL.html and selected the latest 32bit version (I had the 64bit installed at first attempt but read elsewhere people had trouble with this so swtiched to 32bit)
3. I have updated the LIB and INCLUDE locations to the relevant ../openssl/include and ../openssl/lib locations and tried re-running the pip install but I keep gettng the same message. I've done this within the terminal within PyCharm and the standard CMD prompt.
4. I'm running PIP version 19.0.3

我确定我缺少一些超级简单的东西.只是不知道什么.

I'm sure I'm missing something super simple. Just don't know what.

我正在尝试使用加密技术(本来计划使用pyopenssl，但已经注意到它已被加密技术取代)为我的flask应用程序启用HTTPS.

I'm looking to use the cryptography (originally planned to use pyopenssl but have noticed it's been superceded by cryptography) to enable HTTPS for my flask application.

有什么我想念的吗?我感觉在那里.

Is there anything I've missed? I feel there is.

非常感谢

推荐答案

您可以尝试

1..打开 PyCharm .

2.转到File -> settings -> Project:test(test means your project name) -> select project interpretor -> click add button

3..点击添加按钮并搜索 cryptography然后安装.

3. after clicking add button and search cryptography then install it.

最终运行程序.
