pip install XXX; SSL dependency in Win10

Hi Expert,

I got the following error while trying to install any 3rd party module from PYPI.

pip install XXX

pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available.

 

Could not fetch URL https://pypi.python.org/simple/pyvisa/: There was a problem confirming the ssl certificate: Can't connect to HTTPS URL because the SSL module is not available. - skipping

Hi Mingliang,

We build CPython with OpenSSL support, hence it is strange that pip complains about SSL/TLS support being absent. Please run the following commands and paste its output here: 

  1. where pip
  2. <path_to_Intel_Distribution_for_Python>\Scripts\conda.exe list
  3. <path_to_Intel_Distribution_for_Python>\python.exe -c "import ssl; import _ssl; print(ssl.OPENSSL_VERSION)"

As we continue investigating this, I can suggest a temporary workaround that you could use to circumvent this issue. You can try to fetch pyvisa using one of the following commands:

1. <path_to_Intel_Distribution_for_Python>\Scripts\pip.exe install --index-url=http://pypi.python.org/simple/ pyvisa
OR
2. <path_to_Intel_Distribution_for_Python>\Scripts\pip.exe install --trusted-host pypi.python.org pyvisa

Thanks,
Rohit

Hello Rohit,

Still not work. I have tried IntelPython3 and miniconda. Both said SSL unavailable in Python.

And I don't have CPython or OpenSSL  ...

C:\IntelPython3\Scripts>pip.exe install --index-url=https://pypi.python.org/simple/ pyvisa

pip was unusable with both IDP and Miniconda on Windows. The problem was root-caused to a conflicting library (libeay32.dll) that was installed in system path. At run-time, loading of this library gained precedence over what we ship with our distribution. There was a version conflict and the execution would fail with "ImportError: DLL load failed: The operating system cannot run %1.". Removing this extraneous library from system path resolved the issue.

Hi there

I have the same problem, but your solution sounds a bit unclear. Could you please clearly specify how you got around this problem.

Currently I have resolved to download the Wheels but when trying to install the wheel, it is trying to get it's dependency and again... SSL

 

 

thanx A LOT

Thanks Rohit.  There are some people getting this problem inside venv (see https://github.com/pypa/virtualenv/issues/1139). ;I got issue using Intel Python Distribution *and* `python -m venv` to create my venv. It seems to be an issue with `ssl` module, having nothing to do with `pip`:

```
(venv) C:\Users\ceefour\git\tews\ecn-svc>python
Python 3.6.3 |Anaconda custom (64-bit)| (default, May  3 2018, 23:39:44) [MSC v.1900 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.

>>> import ssl
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "C:\ProgramData\Anaconda3\lib\ssl.py", line 101, in <module>
    import _ssl             # if we can't import it, let the error propagate
ImportError: DLL load failed: The operating system cannot run %1.
>>>
```
 
Note that the bug only triggered when using Intel Python inside a venv. When using the base env, it works:
 
```
(base) C:\Users\ceefour>python
Python 3.6.3 |Anaconda custom (64-bit)| (default, May  3 2018, 23:39:44) [MSC v.1900 64 bit (AMD64)] on win32

>>> import ssl
>>> 
```
 
I have _lots_ of `libeay32.dll` inside of `C:\Program Files`, including one in `C:\ProgramData\Anaconda3\Library\bin`
 
I have tried moving `C:\ProgramData\Anaconda3\Library\bin` to front of `PATH`, but still error happens.

I can solve this problem by adding dir path of intel-python which has libeay32.dll (in my case C:\Devs\IntelPython3\pkgs\openssl-1.0.2l-vc14_intel_0\Library\bin) in system environment as top most position.

Try using

pip3 install <Module>

It worked out for me. I was getting the same error using pip install while installing Django.

using pip3 install Django it worked
