@wsds 我说的是 python3.7 的那个 python， 你这个用的是 python2.7 版本， 你可以用 python -m pip 来安装包

[wsds]

@chenqh 装不了，一样报错

[ysc3839]

@wsds 4# 1 not fully installed or removed.
有个软件安装失败了？建议你重装系统。
另外，你是怎么升级 Python 3.7 的？

[wsds]

@ysc3839 为了一个 python 我重装系统，这成本有点高
直接了编译安装的

[ysc3839]

@wsds 编译安装一般不会装到系统里面的，会装到用户目录或者 /opt 下面。
而且 Ubuntu 都有 Python 的 ppa 源。

可能是那条命令里面的 py 环境是指向 2，修改下试试

[likuku]

所以，系统自带的 python 就不要乱动，想用其他版本，那就用 pyenv 好了。
