# 👇️ for Debian (Ubuntu)
sudo apt-get install python3.10-dev linux-headers-virtual make gcc libtool

# 👇️ for Fedora
yum install python3-devel gcc kernel-devel kernel-headers make diffutils file

# 👇️ for Alpine Linux
apk add --virtual build-deps file make gcc musl-dev libffi-dev

您可以在gevent 的 pypi 页面的安装部分阅读有关先决条件的更多信息
。

错误的最常见原因是具有过时的版本pip。

以下是pip在所有操作系统上升级的命令。

哪个命令有效取决于您的操作系统和 Python 版本。

壳


# 👇️ if you have pip already installed
pip install --upgrade pip

# 👇️ if your pip is aliased as pip3 (Python 3)
pip3 install --upgrade pip

# 👇️ if you don't have pip in your PATH environment variable
python -m pip install --upgrade pip

# 👇️ if you don't have pip in your PATH environment variable
python3 -m pip install --upgrade pip

# 👇️ if you have easy_install
easy_install --upgrade pip

# 👇️ if you get a permissions error
sudo easy_install --upgrade pip

# 👇️ if you get a permissions error when upgrading pip
pip install --upgrade pip --user

# 👇️ upgrade pip scoped to the current user (if you get permissions error)
python -m pip install --user --upgrade pip
python3 -m pip install --user --upgrade pip

# 👇️ Installing directly from get-pip.py (MacOS and Linux)
curl https://bootstrap.pypa.io/get-pip.py | python

# 👇️ if you get permissions issues
curl https://bootstrap.pypa.io/get-pip.py | sudo python

# 👇️ alternative for Ubuntu/Debian
sudo apt-get update && apt-get upgrade python-pip

# 👇️ alternative for Red Hat / CentOS / Fedora
sudo yum install epel-release
sudo yum install python-pip
sudo yum update python-pip

现在pip已经升级，尝试运行pip install gevent命令。

壳


pip install gevent
pip3 install gevent

python -m pip install gevent
python3 -m pip install gevent

# 👇️ for Anaconda
conda install -c anaconda gevent

如果错误未解决，请同时升级setuptools和wheel软件包。

壳


pip install --upgrade setuptools wheel

pip3 install --upgrade setuptools wheel

python3 -m pip install --upgrade setuptools wheel

升级后尝试重新运行该pip install命令。setuptoolswheel

如果这没有帮助，请尝试使用该
选项运行pip install命令。--upgrade

壳


pip install gevent --upgrade
pip3 install gevent --upgrade

python -m pip install gevent --upgrade
python3 -m pip install gevent --upgrade

如果错误未解决，请尝试安装带有
--no-cache-dir禁用缓存选项的软件包。

壳


pip install gevent --no-cache-dir
pip3 install gevent --no-cache-dir

如果这没有帮助，请使用该--pre选项来包括包的预发布和开发版本。

壳


pip install gevent --pre
pip3 install gevent --pre

python -m pip install gevent --pre
python3 -m pip install gevent --pre

该--pre选项使其pip包含包的预发布和开发版本。默认情况下pip只查找稳定版本。

这有时会有所帮助，因为包的预发布版本可能适用于您的 Python 版本。 wheel

如果错误未解决，请尝试运行带选项的pip install命令
。--no-use-pep517

壳


pip install --no-use-pep517 gevent
pip3 install --no-use-pep517 gevent

python -m pip install --no-use-pep517 gevent
python3 -m pip install --no-use-pep517 gevent

如果这没有帮助，请尝试安装另一个版本的gevent.

pip install package==您可以通过运行命令来检查软件包的可用版本
。

壳


pip install gevent==

pip 列出包的所有可用版本

输出包含包的所有版本的元组，从最旧的版本到最新的版本。

选择另一个版本的包并尝试安装它。这是一个例子。

壳


pip install gevent==22.8.0

如果这没有帮助，请尝试创建一个虚拟环境。

Create a virtual environment #

To solve the “Could not build wheels for gevent” error:

Create a virtual environment.
Activate the virtual environment.
Run the pip install command with the virtual environment active.

shell


# 👇️ use correct version of Python when creating VENV
python3 -m venv venv

# 👇️ activate on Unix or MacOS
source venv/bin/activate

# 👇️ activate on Windows (cmd.exe)
venv\Scripts\activate.bat

# 👇️ activate on Windows (PowerShell)
venv\Scripts\Activate.ps1

# 👇️ install the specific package in the virtual environment
pip install gevent

If the python3 -m venv venv command doesn’t work, try the following 2
commands:

python -m venv venv
py -m venv venv

Make sure to use the correct command to activate your virtual environment
depending on your operating system and your shell.

Your virtual environment will use the version of Python that was used to create
it.

Try running pip install in verbose mode #

If none of the suggestions helped, try running the pip install command in
verbose mode.

shell


pip install gevent -vvv

pip3 install gevent -vvv

python -m pip install gevent -vvv

The -v option stands for verbose mode and can be used up to 3 times.

When the pip install command is run in verbose mode, the command shows more
output and how the error occurred.

Check if your Python version is supported by the package #

The error “ERROR: Could not build wheels for gevent” is sometimes caused when
the package you are trying to install doesn’t have available wheels for your
version of Python.

You can check your Python version with the python --version command.

shell


python --version

检查 python 版本

You can check if a package has wheels available for a specific Python version in
the Download files section of the
package’s pypi page.

For example, cp310 in the name of a file under “Built Distributions” means Python version 3.10 is supported for the specific operating system.

If the .whl files are not available for your version of Python, you can
download an older version.

You can download a specific Python version that is supported by the package if
the package doesn’t support the latest Python version.

Different versions are available in the
“Looking for a specific release” table.

安装特定的python版本

Make sure to tick the following options if you get prompted:

Install launcher for all users (recommended)
Add Python to PATH (this adds Python to your PATH environment variable)

Conclusion #

To solve the error “Could not build wheels for gevent”, run the
pip install --upgrade pip command to upgrade your pip version, install the
prerequisites and rerun the pip install gevent command.
