python – Pip安装Twisted Error 1
作者：互联网
在Mac osx 10.9.4上使用pip install twisted in virtualenv时,我得到了这个结果：
命令“python setup.py egg_info”失败,错误代码1在/ private / var / folders / 9r / 3b500gbs3093ms87mqqbckr80000gn / T / pip-build-doynftp7 / twisted /
我不知道该如何解决.我使用了easy_install,但是我遇到了SSL验证问题.有人有类似的问题吗？其余的错误消息如下.
Collecting twisted

Complete output from command python setup.py egg_info:

解决方法:
我在Mac OSX 10.11.6上使用全新安装的Python3.6.1在新的virtualenv中遇到了同样的问题.在我的情况下,我安装了旧版本的Twisted依赖增量,这阻止了安装.
pip install --upgrade incremental
pip install Twisted
注意I：我从需求文件中安装了一整套软件包,其中指定了相同的增量版本.我真的很想知道为什么增量的升级有助于并且不知道究竟出了什么问题.如果有人能澄清,那就太好了.
注意II：在新安装时,在Twisted之前安装增量似乎也是必要的[使用CentOS7时经验丰富].
注意III：问题已传达给令人惊叹的Twisted社区,一旦Twisted ticket #9457实施,在发布中这个问题和我的答案应该过时了.
