PIP module has no attribute "main"
提问by DCUFan7
EDIT: The computer in question was a client machine with restrictions on what software could be installed. I'm unsure if that may have been a cause of the issue or if the client's IT department gave the machine a corrupted version of pip. The recommended answers below probably would have worked but were blocked by the company's IT department and required admin login to do. I have since left that project and hope to avoid similar situations.
编辑：有问题的计算机是一台客户端机器，对可以安装的软件有限制。我不确定这是否可能是问题的原因，或者客户的 IT 部门是否给机器提供了损坏的 pip 版本。下面推荐的答案可能会奏效，但被公司的 IT 部门阻止，需要管理员登录才能执行。我已经离开了那个项目，希望避免类似的情况。

they made a refactoring. you can support both 9 and 10 pip by using:
他们进行了重构。您可以使用以下方法同时支持 9 和 10 pip：
try:
from pip import main as pipmain
except:
from pip._internal.main import main as pipmain
and then use pipmain as you used pip.main. for example
然后像使用 pip.main 一样使用 pipmain。例如
pipmain(['install', "--upgrade", "pip"])
pipmain(['install', "-q", "package"])

My issue was related to my IDE (PyCharm). older versions of PyCharm does not support pip v10. Upgrading PyCharm solved it for me.
我的问题与我的 IDE (PyCharm) 有关。旧版本的 PyCharm 不支持 pip v10。升级 PyCharm 为我解决了这个问题。

For more recent versions of pip (pip>=10.0.0), the functionality described in the other answers will no longer work. I recommend running the pipwith subprocessas follows:
对于较新版本的 pip (pip>=10.0.0)，其他答案中描述的功能将不再起作用。我建议按如下方式运行pipwith子进程：
import subprocess
import sys
my_path = <a path to the WHL file>
command_list = [sys.executable, "-m", "pip", "install", my_path]
with subprocess.Popen(command_list, stdout=subprocess.PIPE) as proc:
print(proc.stdout.read())
This solution uses the current python executable to run the pip command as a commandline command. It was inspired by the solution mentioned here.
此解决方案使用当前的 python 可执行文件将 pip 命令作为命令行命令运行。它的灵感来自这里提到的解决方案。
