Answer 1

看起来setuptools>=58打破了对use_2to3的支持:

setuptools changelog for v58

因此，您应该将setuptools更新为setuptools<58或避免在设置参数中使用use_2to3的软件包。

我也有同样的问题，pip==19.3.1

Answer 2

我安装了setuptools==58，它为我工作。pip install setuptools==58。以前在我的设备上运行的setuptools==69的错误。最后为我保存了setuptools版本58。

Answer 3

这对我很有效。

pip install --upgrade pip setuptools==57.5.0 

Answer 4

pip install setuptools==58"对我有用。当我将ubuntu升级到22.04和python 3.10时，setuptools的版本是59。我为一个已有的django项目创建了一个干净的虚拟环境。它只有两个包:

的pip列表包版本

---

pip 22.0.2setuptools 59.6.0 '

然后我将setuptools降级为58，如pip install setuptools==58.0.0。之后的pip install -r requirements.txt没有上面这样的错误。

Answer 5

将MongoEngine升级到>= 0.20也可以解决问题，因为Python2支持(因此use_2to3)在0.20中被删除

Answer 6

我正在使用Windows 11，这些解决方案不起作用。我安装了pybluez2。Windows上的python版本>= 3.9。

pip install pybluez2
