卸载用户在macOS High Sierra上使用pip安装的所有软件包

Question

我错误地使用pip在全局环境中安装了软件包。我想知道，如果它是一个好主意，卸载现有的Python提供的说明在OS上这里，并使用所提供的说明自制重新安装在这里了？或者有什么办法摆脱我使用pip安装的所有软件包及其依赖项。

我在macOS High Sierra上使用Python 2.7.10。编辑：建议方法的问题：

正如CloC在评论部分中建议的那样，我尝试通过键入以下内容从全局环境中卸载所有软件包：

pip freeze > to_delete.txt

然后

sudo -H pip uninstall -y -r to_delete.txt

但是我在终端中收到以下错误：

Exception: Traceback (most recent call last): File "/Library/Python/2.7/site-packages/pip-18.0-py2.7.egg/pip/_internal/basecommand.py", line 141, in main status = self.run(options, args) File "/Library/Python/2.7/site-packages/pip-18.0-py2.7.egg/pip/_internal/commands/uninstall.py", line 74, in run auto_confirm=options.yes, verbose=self.verbosity > 0, File "/Library/Python/2.7/site-packages/pip-18.0-py2.7.egg/pip/_internal/req/req_install.py", line 864, in uninstall uninstalled_pathset.remove(auto_confirm, verbose) File "/Library/Python/2.7/site-packages/pip-18.0-py2.7.egg/pip/_internal/req/req_uninstall.py", line 221, in remove renames(path, new_path) File "/Library/Python/2.7/site-packages/pip-18.0-py2.7.egg/pip/_internal/utils/misc.py", line 276, in renames shutil.move(old, new) File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/shutil.py", line 299, in move copytree(src, real_dst, symlinks=True) File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/shutil.py", line 208, in copytree raise Error, errors Error: [('/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/macholib/dyld.py', '/private/tmp/pip-uninstall-3QWFII/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/macholib/dyld.py', "[Errno 1] Operation not permitted: '/private/tmp/pip-uninstall-3QWFII/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/macholib/dyld.py'"), [...], "[Errno 1] Operation not permitted: '/private/tmp/pip-uninstall-3QWFII/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/macholib'")]

您当然不应该重新安装python才能进行全新的软件包安装。

通过首先列出并卸载它们，可以轻松地从全局环境中卸载所有软件包：

pip freeze > to_delete.txt

然后：

pip uninstall -y -r to_delete.txt

如果不想全部卸载，则可以删除要保留在to_delete.txt第一步中创建的文件中的行。
