Python 安装pyopenssl时满足cffi.ffiplate.VerificationError

我使用的是Ubuntu 14.04。我试图在我的机器上安装pyopenssl。 然而，它总是失败与此信息。我在谷歌上搜索过，但没有找到任何解决方案：

gcc -pthread -shared /tmp/pip_build_pi314/cryptography/cryptography/hazmat/bindings/__pycache__/cryptography/hazmat/bindings/__pycache__/_Cryptography_cffi_79a5b0a3x3a8a382.o -L/home/pi314/anaconda/lib -lcrypto -lssl -lpython2.7 -o /tmp/pip_build_pi314/cryptography/cryptography/hazmat/bindings/__pycache__/_Cryptography_cffi_79a5b0a3x3a8a382.so

因为您在Ubuntu上，所以需要安装libssl dev

sudo apt get安装libssl dev

您还需要libffi-devel和python-dev

既然你在Ubuntu上，你需要安装libssl-dev

sudo apt get安装libssl dev

您还需要libffi-devel和python-dev

sudo apt get install libffi dev python dev

适合我。谢谢。在这里，百胜可能不是正确的选择。使用apt get和特定于debian的ssl库。请参阅确切的命令。对我有用。谢谢。在这里，百胜可能不是正确的选择。使用apt get和特定于debian的ssl库。请参阅确切的命令。我认为正确的包是
