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
