问题:
在电脑终端安装了pyquery且能正常导入,但在pycharm中不能导入,提示没有该模块。在pycharm setting中安装出现如下错误:
错误原因:当前pip版本中没有main(),不降级的情况下解决办法如下:
找到pycharm安装目录下helpers/packaging_tool.py文件,找到如下代码:
#从104行开始
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)
修改为以下代码:
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)
方法二:降级pip版本
python -m pip install --upgrade pip==9.0.3
