"ssl module in Python is not available"

提问by gRookie

still advancing in my tutorial to learn python, I was told to do

在我的教程中仍在推进学习 python，我被告知要做

sudo -H pip install requests

I get the following :

我得到以下信息：

pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available.
Collecting requests
  Could not fetch URL https://pypi.python.org/simple/requests/: There was a problem confirming the ssl certificate: Can't connect to HTTPS URL because the SSL module is not available. - skipping
  Could not find a version that satisfies the requirement requests (from versions: )
No matching distribution found for requests

would someone know what I need to do to fix that once for all ?

有人会知道我需要做什么才能一劳永逸地解决这个问题吗？

thanks so much in advance

非常感谢提前

I use Linux distros and face the problem since the new installation of Python 3.6. I tried a couple of solution and finally solved the problem. The steps I followed are as below.

自新安装 Python 3.6 以来，我使用 Linux 发行版并面临问题。我尝试了几种解决方案，最终解决了问题。我遵循的步骤如下。

On Debian like distros

在 Debian 之类的发行版上

sudo apt-get install build-essential checkinstall libreadline-gplv2-dev ibncursesw5-dev libssl-dev libsqlite3-dev tk-dev libgdbm-dev libc6-dev libbz2-dev

Change the directory to the Python3.6 location

将目录更改为 Python3.6 位置

cd /path/to/Python3.6/Module/

In the module directory, open the Setupfile with your preferred text editor

在模块目录中，Setup使用您喜欢的文本编辑器打开文件

vi Setup

Search for SSLand uncomment the related lines.

搜索SSL并取消注释相关行。

ssl _ssl.c \
    -DUSE_SSL -I$(SSL)/include -I$(SSL)/include/openssl \
    -L$(SSL)/lib -lssl -lcrypto

Save the file and on the root folder of your Python package, run the following command.

保存文件并在 Python 包的根文件夹中运行以下命令。

make
sudo make install

And finally, run the pip3to install your required module(s).

最后，运行pip3以安装所需的模块。

Running ./configurewith --enable-optimizationsdid the trick.

./configure与运行一起--enable-optimizations做的伎俩。

Here are the steps that worked for me on a Ubuntu 16.04 LTS box-

以下是在 Ubuntu 16.04 LTS 机器上对我有用的步骤-

1. The lines related to sslin the Modules/Setup*files are commented

2. cd to the directory where you have the Python tar extracted

   cd /../../../Python-3.7.4/

3. Run configure with optimizations enabled

   ./configure --enable-optimizations

4. Run make and then make install

   make

   make install

1. 相关线路ssl在Modules/Setup*文件注释

2. cd 到您提取 Python tar 的目录

   cd /../../../Python-3.7.4/

3. 在启用优化的情况下运行配置

   ./configure --enable-optimizations

4. 运行 make 然后 make install

   make

   make install

I encountered this problem running pip on Powershell on Windows, using the Anaconda distribution. I was running it inside VSCode, but I don't think it makes much difference.

我使用 Anaconda 发行版在 Windows 上的 Powershell 上运行 pip 时遇到了这个问题。我在 VSCode 中运行它，但我认为它没有太大区别。

A quick turnaround for me was installing what I needed using the Anaconda prompt, which works fine.

对我来说，快速周转是使用 Anaconda 提示符安装我需要的东西，它工作正常。

I encountered the same problem in Windows 10.

我在 Windows 10 中遇到了同样的问题。

What I did was:

我所做的是：

Step 1:go to https://pypi.python.org/simple/requestsand download the latest version (e.g., requests-2.21.0.tar.gz).

第 1 步：前往https://pypi.python.org/simple/requests并下载最新版本（例如 requests-2.21.0.tar.gz）。

Step 2:unzip the downloaded file into a folder (e.g., c:\temp\requests-2.21.0). You can use 7zip for that purpose.

第二步：将下载的文件解压到一个文件夹中（例如，c:\temp\requests-2.21.0）。为此，您可以使用 7zip。

Step 3:pip install c:\temp\requests-2.21.0

第三步：pip install c:\temp\requests-2.21.0

Note: pip can also install a local folder.

注意：pip 也可以安装本地文件夹。

It worked for me.

它对我有用。
