Python 3.7蟒蛇环境-import_ssl DLL 加载失败错误

我使用 Python = 3.7创建了 anaconda 环境，但是遇到了 _ ssl 和 DLL 错误的问题。当我试图返回到我的基本环境时，如下图所示，我在完成后台进程时遇到了麻烦，这种情况会一直持续下去。

I had the same issue on Windows 10 Pro x64 and PyCharm CE 2018.3

A solution that worked for me: Re-install Anaconda3 for all users (with Admin priveledges) and choose "add python.exe to Path" (even though it is nor recommended). Then PyCharm connected successfully without this error.

A work around that also worked: Use another environment (pyenv or conda). It worked for me when I faced the same issue on

Some other suggestions I saw on Internet: run Anaconda3\Scripts>conda update --all but this threw the HTTP connection error rises, which might be related.

This can be fixed by manually adding in the PATH variables in PyCharm to the console.

  1. Open your Anaconda cmd
  2. Activate your Conda environment
  3. Get the full PATH value by typing echo %PATH%
    • if you are on Windows 7/can't copy the output, cd the cmd to your desktop and type echo %PATH% > path_val.txt
    • this will create a txt file so you can copy/paste the values easier.
  4. In PyCharm, go to Settings -> Build, Execution, Deployment -> Console -> Python Console -> click the folder on the right of Environment variables.
  5. Click the plus button to add a new Environment Variable
    • The name should be PATH
    • The value is the entire output from the echo %PATH% command above.
  6. Click OK, then apply.

You can try to set system environment variables, like "C:\Python\Anaconda3;C:\Python\Anaconda3\Scripts; C:\Python\Anaconda3\Library\bin;".

Only "C:\Python\Anaconda3\Scripts;" is not enough, and it works to me.

Incase someone is searching for Eclipse PyDev, It's same as Rob's answer.

No. 4 can be found at Window -> Preferences -> PyDev -> Interpreters -> Python Interpreters -> Environment -> Click New and add PATH

another solution: edit python3.7's site.py(in Lib dir):

from os.path import join, abspath, dirname
base_path = dirname(dirname(abspath(__file__)))
os.environ['PATH'] = '%s%s' % (
os.environ['PATH'],
join(base_path, 'Library', 'bin'),
)

None of the above worked for me, but instead it was a problem with OpenSSL on Windows 10 Enterprise. I fixed it by downloading and installing OpenSSL from here: https://slproweb.com/products/Win32OpenSSL.html

I have answerd this here, to my understanding this error is caused by the missing/misplacement of libcrypto file in anaconda3/DLLs folder:

From anaconda3\Library\bin copy below files and paste them in anaconda3/DLLs: 

-   libcrypto-1_1-x64.dll
-   libssl-1_1-x64.dll
小开

if running under a virtual env (i.e. your have issued the command: conda activate <env_name>)

The files (libcrypto-1_1-x64.dll and libssl-1_1-x64.dll) to copy are found under: C:\USER<username>.conda\envs<env_name>\Library\bin

They have to be copied into: C:\USER<username>.conda\envs<env_name>\DLLs

I have updated to Python 3.8 (with miniconda) and it did not work with Pycharm generating "anaconda-environment-import-ssl-dll-load-fail-error". I have tried several proposals here and tweaked env variables in different way w/o much success. Finally I have updated to Pycharm 2020.2.3 and it worked like a charm, no tweaks ..

In my case the error was a result of spinning pipenv from non-base conda env. Setting variable in PyCharm or moving files in base anaconda structure didn't help, because PyCharm looked for these DLLs in my conda env in the middle.

So I had to move files from base conda structure: C:\Users<username>\AppData\Local\Continuum\anaconda3\Library\bin

To my conda env from which I spinned the final Pipenv I use in PyCharm: C:\Users<username>\AppData\Local\Continuum\anaconda3\envs<conda_env_name>\DLLs

The files I had to move to have IPython work correctly:

libcrypto-1_1-x64.dll
libssl-1_1-x64.dll
sqlite3.dll
sqlite3.exe

The reason is that not all libraries/binaries are propagated to the virtual envs. Virtual envs are able to find these files in "root Python". Venvs stay lighter thanks to not copying them.

However, PyCharm gets confused in a setup such as mine, and treats the conda env in the middle as a "root Python", and can't find the libraries/bins. This problem can potentially make itself apparent with other dlls or bins.

It may be worth to move all missing files this way.

I had the same issue and my main IDE is Sublime Text 4.

Environment: Windows 10 with Anaconda

What I needed: from cryptography.fernet import Fernet

The marked solution was unachievable for me and the following answer solved it right away:

pip install --upgrade pip
pip uninstall pyopenssl cryptography
pip install pyopenssl cryptography

Validate with:

python -v -c "from OpenSSL import SSL"
