ImportError: DLL load failed while importing _ssl #347
Description
Hi, I build this project on Win10. I have built python.exe successfully. And install pip using ensurepip. But when I install numpy with pip, there have errors as follows:
`WARNING: pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available.
Could not fetch URL https://pypi.tuna.tsinghua.edu.cn/simple/pip/: There was a problem confirming the ssl certificate: HTTPSConnectionPool(host='pypi.tuna.tsinghua.edu.cn', port=443): Max retries exceeded with url: /simple/pip/ (Caused by SSLError("Can't connect to HTTPS URL because the SSL module is not available.")) - skipping`
Then I run this command:
python -m ssl
Error are:
Traceback (most recent call last):
File "D:\Project\Python\python-cmake-buildsystem\python-install\Lib\runpy.py", line 197, in _run_module_as_main
return _run_code(code, main_globals, None,

File "D:\Project\Python\python-cmake-buildsystem\python-install\Lib\ssl.py", line 98, in <module>
import _ssl # if we can't import it, let the error propagate
ImportError: DLL load failed while importing _ssl: 找不到指定的模块。
And I found there is a fille called _ssl.pyd in the folder (this path is added into PATH variable):
"<some_path>\python-install\Lib\lib-dynload\_ssl.pyd"
Beside I also add the path which included the following file to the PATH variable:
libcrypto-1_1-x64.dll, libssl-1_1-x64.dll
But it still can't find the ssl module.
These information are from CMake-GUI (There is no error about OpenSSL)：
