在 WSL 上将 python3 设置为版本 3.7

我可以将 WSL Ubuntu 18.04 上的默认 Python 3.6.5 更改为 3.7 吗？这样当我检查时python3 --version，3.7.x我也可以将该版本与 pip3 一起使用。谢谢

python3以下是更改命令以指向您的版本的步骤python3.7（假设您已经安装了 3.7）。请根据您的环境调整路径

# 1 - Identify your location of `python3` using the `which` command
which python3
# returns something like
/usr/local/bin/python3

# 2 - Identify your location of `python3.7` using the `which` command
which python3.7
# returns something like
/usr/local/bin/python3.7

# 3 - Get directory listing of python3 folder (from 1 above)
# using grep to filter results containing 'python'
ll /usr/local/bin | grep -i python
# returns something like below - notice the arrow after python3
# the arrow indicates a symbolic link
lrwxrwxrwx  1 root root       18 Jul  4  2018 python3 -> /usr/bin/python3.6*
-rwxr-xr-x  2 root root 14777608 Nov  3 00:36 python3.7*
-rwxr-xr-x  2 root root 14777608 Nov  3 00:36 python3.7m*
-rwxr-xr-x  1 root root     3097 Nov  3 00:37 python3.7m-config*
-rwxr-xr-x  1 root root  4522328 Feb 22 17:24 python3x*

# 4 - Test creating a symbolic link using sudo to get root privileges
#     enter password if/when prompted 
sudo ln -s /usr/local/bin/python3.7 /usr/local/bin/test37

# 4 - verify test
test37 --version
# Desired output
Python 3.7.1

# 5 - remove test and python3
sudo rm /usr/local/bin/test37
sudo rm /usr/local/bin/python3

# 6 - creating python3 symbolic link using sudo to get root privileges
#     enter password if/when prompted 
sudo ln -s /usr/local/bin/python3.7 /usr/local/bin/python3

# 7 - verify
python3 --version
# Desired output
Python 3.7.1

当然，最符合 Python 风格的是使用虚拟环境。
