![pip 在 Mac Mojave 上无法运行](https://linux22.com/image/1599813/pip%20%E5%9C%A8%20Mac%20Mojave%20%E4%B8%8A%E6%97%A0%E6%B3%95%E8%BF%90%E8%A1%8C.png)
当我尝试在 Mac Mojave 上使用 pip 命令时,收到此错误:
Traceback (most recent call last):
File "/usr/local/lib/python3.7/site-packages/pkg_resources/__init__.py", line 583, in _build_master
ws.require(__requires__)
File "/usr/local/lib/python3.7/site-packages/pkg_resources/__init__.py", line 900, in require
needed = self.resolve(parse_requirements(requirements))
File "/usr/local/lib/python3.7/site-packages/pkg_resources/__init__.py", line 791, in resolve
raise VersionConflict(dist, req).with_context(dependent_req)
pkg_resources.VersionConflict: (pip 19.2.1 (/usr/local/lib/python3.7/site-packages), Requirement.parse('pip==19.1.1'))
在处理上述异常的过程中,又发生了另一个异常:

我该如何修复它?
答案1
由于缺乏有关 Python 项目、pip 版本和实际命令的详细信息,我只能推断出现此错误消息是因为您的 Python 项目明确请求了pip 19.1.2
。例如,您的 requirements.txt 文件可能有
pip=19.1.2
使用更宽松的版本依赖性
您可以将要求更改为
pip>=19.1.0,<=20.0
升级 pip
升级pip到最新版本
pip install --upgrade pip
