命令“python setup.py egg_info”失败，/tmp/../ 中的错误代码为 1

Question

使用 pip 安装依赖项时出现以下错误：

pip9.exceptions.InstallationError 命令“python setup.py egg_info”在 /tmp/tmpoons7qgkbuild/opencv-python/ 中失败，错误代码为 1

下面是在pipenv install opencv-python最近的 linux (5.4.0 x64) 系统上运行命令的结果。

如何修复 pip9.exceptions.InstallationError

确保您的pip和版本setuptools足以用于manylinux2014 wheels.

sudo python3 -m pip install -U pip
sudo python3 -m pip install -U setuptools

解释

对我来说，python setup.py egg_info可能是因为最近 python 轮子的变化而失败manylinux1 wheels，manylinux2014 wheels根据open-cv faq被替换。

Answer 2

我通过此链接https://www.edureka.co/community/69396/command-python-setup-info-failed-error-build-8nhf9w2t-grpcio并使用以下命令解决了类似的问题：

$ pip3 install --upgrade setuptools
$ pip3 install --upgrade pip

Answer 3

我有同样的问题。

当我执行时：

pip install jupyterlab

它抛出一个错误：

Command "python setup.py egg_info" failed with error code 1 in /private/tmp/pip-build-p0u6Wd/jupyterlab

我尝试了很多方法，但都失败了。

最后，我发现我的电脑里有一个花药点：

$ pip --version
pip 6.1.1 from /Library/Python/2.7/site-packages (python 2.7)

$ pip3 --version
pip 21.2.4 from /usr/local/lib/python3.9/site-packages/pip (python 3.9)

我使用pip3修复问题：

pip3 install jupyterlab
