Python 2.7에 Python 3.7.3을 설치할 때 Python 명령을 찾을 수 없음 오류

나는 Python 2를 가지고 있습니다.

# which python
/bin/python

# python --version
Python 2.7.5

다음 기사를 사용하여 Python 3.7을 설치하고 있습니다.https://wiki.centos-webpanel.com/install-django

파이썬을 설치한 후

# cd /usr/local/src
# wget https://www.python.org/ftp/python/3.7.3/Python-3.7.3.tgz
# tar xvf Python-3.7.3.tgz
# cd Python-3.7.3
# ./configure --with-ensurepip=install --enable-shared
# make
# make install
# ln -s /usr/local/lib/libpython3.7m.so.1.0 /usr/lib64/libpython3.7m.so.1.0

다음 명령을 사용하여 pip를 업그레이드하면 명령을 찾을 수 없습니다.

# pip3.7 install --upgrade pip
bash: pip3.7: command not found

나는 노력했다

# python3.7 pip install --upgrade pip
bash: python3.7: command not found

참고: 설치 후 새 Python 바이너리 경로는 /usr/local/bin/python에 위치합니다.

편집 1:다음 명령을 사용하여 심볼릭 링크를 만들었습니다.

편집 2:python3.7 폴더에서 명령을 실행한 후 다음 오류가 발생합니다.
