【问题标题】：When i use pip install mysqlclient i got error [duplicate]当我使用 pip install mysqlclient 我得到错误 [重复]
【发布时间】：2020-06-15 14:29:46
【问题描述】：

我正在尝试使用 pip 安装 mysqlclient，但它一直遇到错误。我看到一些建议告诉我确保我在 mysqlclient 中的 python 版本是最新的。我已经这样做了。推送到 mysqlclient master 后，我运行了 install 命令，但它给了我以下错误。

我该如何解决这个错误？

pip install mysqlclient

错误：

【问题讨论】：

当我遇到这种情况是因为我有一个 32 位版本的 python。尝试安装 64 位版本的 python？
@Reez0 那我现在该怎么办？
确保 64 位版本的 Python 在您的 PATH 上并运行 pip install mysqlclient。或者完全卸载32位版本的python，然后重试。
@Reez0 如何添加路径？

标签： python django terminal pip mysql-python

【解决方案1】：

您似乎在使用 anaconda，因为您的 python 位于 /opt/anaconda3/bin/python，因此您应该更喜欢使用 conda 命令安装：

conda install mysqlclient

话虽如此，您的原始问题似乎与xcode 有关，您的错误建议运行

xcode-select --install

虽然我不是苹果用户，也不太熟悉在 MacOS 上安装正确的开发工具。如果上述方法不起作用，您也可以考虑在http://apple.stackexchange.com 询问

【解决方案2】：

sudo apt-get install libssl-dev

pip install mysqlclient

这可能是一个重复的问题，起源问题是： Python 3.7, Failed building wheel for MySql-Python

【讨论】：

sudo apt-get install libssl-dev 先生，这不起作用，我遇到了问题，所以我提出了问题，我没有复制任何其他问题。
很抱歉。试试这个命令：sudo apt-get install libevent-dev，然后看看能不能成功。
不，先生，这行不通
对不起，我不知道。
