将 Python 3.x 安装位置添加到 PATH 错误

Question

我有 Python 2 可用

# which python
/bin/python
# python --version
Python 2.7.5

我正在使用以下文章安装 python 3.7 https://wiki.centos-webpanel.com/install-django

安装蟒蛇后

# 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

当我使用以下命令升级 pip 时，它给出的命令未找到

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

我试过了

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

注意：请注意，安装后，新的python二进制路径将位于/usr/local/bin/python

编辑1：我使用以下命令创建了符号链接

Answer 1

我认为你应该从你的终端转到python3.7并使用它： python3.x -m pip install --upgrade pip
