Question

我想在ubunu为我的项目安装scrapy。我使用pip来安装scrapy但是我在安装时总是遇到这个错误。

Traceback (most recent call last):
  File "/usr/bin/pip", line 9, in <module>
    load_entry_point('pip==1.5.6', 'console_scripts', 'pip')()
  File "/usr/lib/python2.7/dist-packages/pkg_resources/__init__.py", line 558, in load_entry_point

那么如何摆脱这个错误并安装scrapy

Answer 1

这件事发生在我身上（尽管有Anaconda，而不是pip）。

我追踪它将pyopenssl从16.0更新为16.2。

我的解决方案是首先重新安装Anaconda（将pyopenssl恢复到16.0）。 （您可能不需要这样做。）

之后，我跑了

sudo apt install python3-openssl

这样做之后，我的问题似乎得到纠正。

Answer 2

我认为你应该先更新你的点子，然后再试一次。我看到pip==1.5.6，omg，它比月亮还年长
