pycharm 安装 flask 时候报错
pycharm版本:2017.2.3 python版本:2.7 pip版本:10.0.1
报错
Traceback (most recent call last): File "/Applications/PyCharm.app/Contents/helpers/packaging_tool.py", line 192, in main retcode = do_install(pkgs) File "/Applications/PyCharm.app/Contents/helpers/packaging_tool.py", line 109, in do_install return pip.main(['install'] + pkgs) AttributeError: 'module' object has no attribute 'main'
原因
新版pip中的main函数已经发生了变化,是pycharm的原因
参考:
PyCharm 2017.3 在pip10.0.0版本中报错(module ‘pip’ has no attribute ‘main’)
解决
方式一
通过 pip 命令手动安装
方式二
根据报错提示中的路径
"/Applications/PyCharm.app/Contents/helpers/packaging_tool.py"
打开文件,如果在mac中找不到文件,可以使用打开
$ vim "/Applications/PyCharm.app/Contents/helpers/packaging_tool.py"
打开后找到如下代码
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)
先注释,添加如下代码:
def do_install(pkgs): try: 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: try: from pip._internal import main except Exception: from pip import main except ImportError: error_no_pip() return main(['uninstall', '-y'] + pkgs)
问题成功解决
