使用pip install安装库时报错：

ERROR: Could not install packages due to an OSError: Missing dependencies for SOCKS support

方法1

完整报错为：

• 缺少代理库，再使用pip install安装pysocks库也是安装不上的，去github上面找到pysocks项目连接，手动安装

# 项目链接
https://github.com/Anorov/PySocks

# 下载下来并且解压 然后进入目录
cd Downloads/PySocks-1.7.0

# 使用管理员权限安装
❯ python3 setup.py install
Warning: 'classifiers' should be a list, got type 'tuple'
running install
error: can't create or remove files in install directory

The following error occurred while trying to add or remove files in the
installation directory:

    [Errno 13] Permission denied: '/Library/Python/3.9/site-packages/test-easy-install-56008.write-test'

The installation directory you specified (via --install-dir, --prefix, or
the distutils default setting) was:

    /Library/Python/3.9/site-packages/

Perhaps your account does not have write access to this directory?  If the
installation directory is a system-owned directory, you may need to sign in
as the administrator or "root" account.  If you do not have administrative
access to this machine, you may wish to choose a different installation
directory, preferably one that is listed in your PYTHONPATH environment
variable.

For information on other options, you may wish to consult the
documentation at:

  https://setuptools.readthedocs.io/en/latest/deprecated/easy_install.html

Please make the appropriate changes for your system and try again.

# 查看是否安装成功
pip3 list

方法2

# 取消所有代理
unset all_proxy && unset ALL_PROXY

# 安装缺失的依赖项
pip3 install pysocks

# 重置代理
source ~/.bashrc
# zsh
source .zshrc
