Python 3.7 anaconda 环境 - 导入 _ssl DLL 加载失败错误
[英]Python 3.7 anaconda environment - import _ssl DLL load fail error
问题描述
I created anaconda environment with Python=3.7 and have trouble with the error of _ssl and DLL.
我用 Python=3.7 创建了 anaconda 环境并且遇到了 _ssl 和 DLL 的错误。 When I tried to get back to my base environment, I have trouble getting the background processes to complete as shown in the figure below, this goes on forever.当我尝试返回我的基本环境时，我无法完成如下图所示的后台进程，这种情况一直持续下去。
The error:错误：

This can be fixed by manually adding in the PATH variables in PyCharm to the console.这可以通过手动将 PyCharm 中的PATH变量添加到控制台来解决。
- Open your Anaconda cmd打开你的 Anaconda cmd
- Activate your Conda environment 激活您的 Conda 环境
- Get the full PATH value by typing
echo %PATH%通过键入echo %PATH%获取完整的 PATH 值- if you are on Windows 7/can't copy the output, cd the cmd to your desktop and type
echo %PATH% > path_val.txt如果您使用的是 Windows 7/无法复制输出，请将 cmd cd 到您的桌面并输入echo %PATH% > path_val.txt - this will create a txt file so you can copy/paste the values easier.这将创建一个 txt 文件，以便您可以更轻松地复制/粘贴值。
- if you are on Windows 7/can't copy the output, cd the cmd to your desktop and type
- In PyCharm, go to Settings -> Build, Execution, Deployment -> Console -> Python Console -> click the folder on the right of Environment variables.在 PyCharm 中，进入Settings -> Build, Execution, Deployment -> Console -> Python Console -> 点击 Environment variables 右侧的文件夹。
- Click the plus button to add a new Environment Variable单击加号按钮添加新的环境变量
- The name should be
PATH名称应为PATH - The value is the entire output from the
echo %PATH%command above.该值是上述echo %PATH%命令的整个输出。
- The name should be

I have answerd this here , to my understanding this error is caused by the missing/misplacement of libcrypto file in anaconda3/DLLs folder:我在这里回答了这个问题，据我所知，这个错误是由 anaconda3/DLLs 文件夹中libcrypto文件丢失/错位引起的：
From
anaconda3\\Library\\bincopy below files and paste them inanaconda3/DLLs:anaconda3\\Library\\bin复制以下文件并将它们粘贴到anaconda3/DLLs：
- libcrypto-1_1-x64.dll
- libssl-1_1-x64.dll

You can try to set system environment variables, like "C:\\Python\\Anaconda3;C:\\Python\\Anaconda3\\Scripts; C:\\Python\\Anaconda3\\Library\\bin;".你可以尝试设置系统环境变量，比如“C:\\Python\\Anaconda3;C:\\Python\\Anaconda3\\Scripts;C:\\Python\\Anaconda3\\Library\\bin;”。
Only "C:\\Python\\Anaconda3\\Scripts;"只有“C:\\Python\\Anaconda3\\Scripts;” is not enough, and it works to me.还不够，它对我有用。

I had the same issue on Windows 10 Pro x64 and PyCharm CE 2018.3我在 Windows 10 Pro x64 和 PyCharm CE 2018.3 上遇到了同样的问题
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).一个对我有用的解决方案：为所有用户（具有管理员权限）重新安装 Anaconda3 并选择“将 python.exe 添加到路径”（即使不推荐）。 Then PyCharm connected successfully without this error.然后 PyCharm 连接成功，没有这个错误。
A work around that also worked : Use another environment (pyenv or conda).一个也有效的解决方法：使用另一个环境（pyenv 或 conda）。 It worked for me when I faced the same issue on当我遇到同样的问题时，它对我有用
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.我在 Internet 上看到的其他一些建议：运行Anaconda3\\Scripts>conda update --all但这会引发 HTTP 连接错误上升，这可能是相关的。

if running under a virtual env (ie your have issued the command: conda activate <env_name>)如果在虚拟环境下运行（即您已发出命令：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要复制的文件（libcrypto-1_1-x64.dll 和 libssl-1_1-x64.dll）位于：C:\\USER<username>.conda\\envs<env_name>\\Library\\bin

In my case the error was a result of spinning pipenv from non-base conda env.在我的情况下，错误是从非基础 conda env 旋转 pipenv 的结果。 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.在 PyCharm 中设置变量或在基本 anaconda 结构中移动文件无济于事，因为 PyCharm 在中间的 conda 环境中寻找这些 DLL。
So I had to move files from base conda structure: C:\\Users<username>\\AppData\\Local\\Continuum\\anaconda3\\Library\\bin所以我不得不从基本 conda 结构中移动文件：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对于我在 PyCharm 中使用的最终 Pipenv 的 conda env： C:\\Users<username>\\AppData\\Local\\Continuum\\anaconda3\\envs<conda_env_name>\\DLLs
The files I had to move to have IPython work correctly:我必须移动的文件才能让 IPython 正常工作：
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.原因是并非所有库/二进制文件都传播到虚拟环境。 Virtual envs are able to find these files in "root Python".虚拟环境能够在“root Python”中找到这些文件。 Venvs stay lighter thanks to not copying them.由于不复制它们，Venvs 保持更轻。
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.但是，PyCharm 在像我这样的设置中感到困惑，并将中间的 conda env 视为“根 Python”，并且找不到库/bin。 This problem can potentially make itself apparent with other dlls or bins.这个问题可能会在其他 dll 或 bin 中变得明显。
It may be worth to move all missing files this way.以这种方式移动所有丢失的文件可能是值得的。

another solution: edit python3.7's site.py(in Lib dir):另一个解决方案：编辑python3.7的site.py（在Lib目录中）：

base_path = dirname(dirname(abspath(__file__)))
os.environ['PATH'] = '%s%s' % (
