Python Archlinux pip和setuptools未升级

我正在尝试

pip

和

setuptools

更新

pycharm

，但出现了以下错误：

错误：未找到python打包工具“pip”

提议的解决办法：

尝试从系统终端运行此命令。确保为位于“/usr/bin/python3.5”的Python解释器安装了正确版本的“pip”

终端命令：

python -V output: Python 3.5.2

which pip output: usr/bin/pip

所以我试着：

python -m pip install -U pip

输出：

/usr/bin/python：没有名为pip的模块

如何更新pip？

应该可以：

pacman -S --force python-pip and pacman -S --force python-setuptools

---

如果希望从

pypi

而不是从存储库获得最新版本，请执行以下操作

pip install -U pip

---

不建议将python软件包与pacman一起安装。因为pacman不识别pip安装的任何包。我认为您应该删除所有使用pip安装的pip包，并使用pacman或virtualenv重新安装所有python包。如果您需要arch的python软件包，您可以通过AUR进行搜索，也可以在虚拟环境中安装任何python软件包。

作为最佳实践，最好在由

pacman

和

pip

管理的软件包之间保持一条线。出现问题的原因是您在pacman管理的pip上安装了一个pipy pip。对于python，我认为

python

本身、

pip

和

virtualenv

应该由

pacman

管理，而所有其他包都应该由

pip

管理。@grochmal这确实应该是一个答案，因为您已经提供了一种防止这种情况的方法——是的，我确实用

pip

升级了

pip

。
