“在安装OpenCV软件包

Question

i激活了环境并做到了：

conda install -c conda-forge opencv
conda install -c conda-forge face_recognition

我可以在PIP列表中看到face_recognition，但是导入时我的代码仍然存在错误。对于openCV，我没有看到列出列表时安装了库，所以我尝试这样做：

pip install opencv

但它给了我这个错误：

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

我不知道我的pip是否有问题，还是我设置的环境无法正常运行，我真的很感谢您对如何解决此问题的任何帮助。

这是您解决问题的线索：

Answer 1

因此，您的SSL模块丢失了。如果您在没有必要的依赖项的情况下或在其他某些Python环境（如Anaconda）中收集Python，则可能发生这种情况。

安装了Python和SSL的必要包装。如果您正在使用Debian/Ubuntu系统，这将是：

sudo apt-get install libssl-dev

如果您在redhat/centos/rocky上：

sudo yum install openssl

对于任何其他系统，请为OpenSSL找到安装软件包。在Windows上，确保以下文件在

..\Anaconda\DLLs

和

..\Anaconda\Library\bin

中：

：

libcrypto-1_1-x64.*
libssl-1_1-x64.*

SSL的必要依赖项需要照顾，重建您的虚拟环境。如果这无法解决您的问题（无论如何），请考虑重建或重新安装Anaconda。
