pip3インストールが機能しない-「pip._vendor.pkg_resources」という名前のモジュールはありません
Python 3（Ubuntu））のパッケージをインストールしようとすると、pip3 install packageName （または Sudo pip3 install packageName）、次のエラーメッセージが表示されます。
Traceback (most recent call last):
File "/usr/lib/python3/dist-packages/pip/_vendor/__init__.py", line 33, in vendored
__import__(vendored_name, globals(), locals(), level=0)
ImportError: No module named 'pip._vendor.pkg_resources'
私は何日も読んでいますが、成功することなく以下を試しました：
- 次のコードを使用して、pip3をアンインストールおよび再インストールします。
Sudo apt-get remove python3-pipに続くSudo apt-get install python3-pip。これは、時々pip3はUbuntuに適切にインストールされません。しかし、うまくいきませんでした。 - 他の投稿は、それが
sslパッケージの問題であり、sslパッケージがPython3でロードされない場合、それが問題であると示唆しました。ただし、次のコマンドではエラーは発生しません：python3 -c "import ssl"。 - 他の投稿では、問題が
requestsパッケージにあることが示唆されました。その後、Sudo apt-get remove python3-requestsに続くSudo apt-get install python3-requestsも役に立たない。
必要なその他の情報：
pip3 --versionは、上記と同じエラーを表示します。dpkg -L python3-pipは次の情報を提供します。/. /usr /usr/lib /usr/lib/python3 /usr/lib/python3/dist-packages /usr/lib/python3/dist-packages/pip-8.1.1.Egg-info /usr/lib/python3/dist-packages/pip-8.1.1.Egg-info/PKG-INFO /usr/lib/python3/dist-packages/pip-8.1.1.Egg-info/dependency_links.txt /usr/lib/python3/dist-packages/pip-8.1.1.Egg-info/not-Zip-safe /usr/lib/python3/dist-packages/pip-8.1.1.Egg-info/requires.txt /usr/lib/python3/dist-packages/pip-8.1.1.Egg-info/entry_points.txt /usr/lib/python3/dist-packages/pip-8.1.1.Egg-info/top_level.txt /usr/lib/python3/dist-packages/pip /usr/lib/python3/dist-packages/pip/baseparser.py /usr/lib/python3/dist-packages/pip/__main__.py /usr/lib/python3/dist-packages/pip/req /usr/lib/python3/dist-packages/pip/req/req_set.py /usr/lib/python3/dist-packages/pip/req/req_install.py /usr/lib/python3/dist-packages/pip/req/__init__.py /usr/lib/python3/dist-packages/pip/req/req_file.py /usr/lib/python3/dist-packages/pip/req/req_uninstall.py /usr/lib/python3/dist-packages/pip/index.py /usr/lib/python3/dist-packages/pip/status_codes.py /usr/lib/python3/dist-packages/pip/utils /usr/lib/python3/dist-packages/pip/utils/setuptools_build.py /usr/lib/python3/dist-packages/pip/utils/appdirs.py /usr/lib/python3/dist-packages/pip/utils/outdated.py /usr/lib/python3/dist-packages/pip/utils/ui.py /usr/lib/python3/dist-packages/pip/utils/logging.py /usr/lib/python3/dist-packages/pip/utils/encoding.py /usr/lib/python3/dist-packages/pip/utils/deprecation.py /usr/lib/python3/dist-packages/pip/utils/__init__.py /usr/lib/python3/dist-packages/pip/utils/filesystem.py /usr/lib/python3/dist-packages/pip/utils/hashes.py /usr/lib/python3/dist-packages/pip/utils/build.py /usr/lib/python3/dist-packages/pip/compat /usr/lib/python3/dist-packages/pip/compat/dictconfig.py /usr/lib/python3/dist-packages/pip/compat/__init__.py /usr/lib/python3/dist-packages/pip/compat/ordereddict.py /usr/lib/python3/dist-packages/pip/models /usr/lib/python3/dist-packages/pip/models/index.py /usr/lib/python3/dist-packages/pip/models/__init__.py /usr/lib/python3/dist-packages/pip/vcs /usr/lib/python3/dist-packages/pip/vcs/Bazaar.py /usr/lib/python3/dist-packages/pip/vcs/Subversion.py /usr/lib/python3/dist-packages/pip/vcs/Mercurial.py /usr/lib/python3/dist-packages/pip/vcs/__init__.py /usr/lib/python3/dist-packages/pip/vcs/git.py /usr/lib/python3/dist-packages/pip/cmdoptions.py /usr/lib/python3/dist-packages/pip/basecommand.py /usr/lib/python3/dist-packages/pip/commands /usr/lib/python3/dist-packages/pip/commands/completion.py /usr/lib/python3/dist-packages/pip/commands/install.py /usr/lib/python3/dist-packages/pip/commands/hash.py /usr/lib/python3/dist-packages/pip/commands/uninstall.py /usr/lib/python3/dist-packages/pip/commands/__init__.py /usr/lib/python3/dist-packages/pip/commands/list.py /usr/lib/python3/dist-packages/pip/commands/search.py /usr/lib/python3/dist-packages/pip/commands/show.py /usr/lib/python3/dist-packages/pip/commands/download.py /usr/lib/python3/dist-packages/pip/commands/wheel.py /usr/lib/python3/dist-packages/pip/commands/freeze.py /usr/lib/python3/dist-packages/pip/commands/help.py /usr/lib/python3/dist-packages/pip/_vendor /usr/lib/python3/dist-packages/pip/_vendor/__init__.py /usr/lib/python3/dist-packages/pip/operations /usr/lib/python3/dist-packages/pip/operations/__init__.py /usr/lib/python3/dist-packages/pip/operations/freeze.py /usr/lib/python3/dist-packages/pip/__init__.py /usr/lib/python3/dist-packages/pip/locations.py /usr/lib/python3/dist-packages/pip/pep425tags.py /usr/lib/python3/dist-packages/pip/exceptions.py /usr/lib/python3/dist-packages/pip/download.py /usr/lib/python3/dist-packages/pip/wheel.py /usr/share /usr/share/man /usr/share/man/man1 /usr/share/man/man1/pip3.1.gz /usr/share/doc /usr/share/doc/python3-pip /usr/share/doc/python3-pip/copyright /usr/bin /usr/bin/pip3 /usr/share/doc/python3-pip/changelog.Debian.gz

注：Python2のpipは正常に機能します。

これは私のために解決しました：
curl -sS https://bootstrap.pypa.io/get-pip.py | Sudo python3
ubuntuサブシステムをいじらない特定のプロジェクトごとにvirtualenvを使用してみてください。
ありがとう@ s_s.411
次のコマンドでこの問題を解決します。
curl -sS https://bootstrap.pypa.io/get-pip.py | Sudo python3
type pip3
hash -r
pip3
私も同じ問題を抱えており、このコマンドで解決しました。
