报错类型
更新pip之后，升级到10.0.1版本，Pycharm安装package出现报错：module ‘pip’ has no attribute ‘main’，报错如下：
Traceback (most recent call last):
File “C:\Program Files\JetBrains\PyCharm 2017.1.1\helpers\packaging_tool.py”, line 192, in main
retcode = do_install(pkgs)
File “C:\Program Files\JetBrains\PyCharm 2017.1.1\helpers\packaging_tool.py”, line 113, in do_install
return pip.main([‘install’] + pkgs)
NameError: name ‘pip’ is not defined
解决办法
根据提示进入到C:\Program Files\JetBrains\PyCharm 2017.1.1\helpers\packaging_tool.py，打开packaging_tool.py文件，修改一下定义的两个函数（根据提示在113行）：
修改前的
def do_install(pkgs):
try:
import pip
except ImportError:
error_no_pip()
return pip.main([‘install’] + pkgs)
def do_uninstall(pkgs):
try:
import pip
except ImportError:
error_no_pip()
return pip.main([‘uninstall’, ‘-y’] + pkgs)
修改为如下（请仔细对照，尤其是加深字体，如果没有改，就会出现Error: Python packaging tool ‘pip’ not found），保存即可。
def do_install(pkgs):
#try:
# import pip
try:
from pip._internal import main
except Exception:
from pip import main
except ImportError:
error_no_pip()
return main([‘install’] + pkgs)
def do_uninstall(pkgs):
#try:
# import pip
try:
from pip._internal import main
except Exception:
from pip import main
except ImportError:
error_no_pip()
return main([‘uninstall’, ‘-y’] + pkgs)
