Question

原谅我问一些简单的问题

我正在通过Namecheap（没有root用户访问权限）在远程服务器上设置Django应用

和我的服务器信息：

Apache版本：2.4.38

MySQL版本：10.1.38-MariaDB-cll-lve

体系结构：x86_64

操作系统：linux

Python：3.7

Django：2.1.7

现在，我正在尝试将mysql DB连接到我的django应用。

但是当我尝试使用pip install mysqlclient

安装连接器 mysqlclient 时

我遇到了这个错误：

  $ pip install mysqlclient

我陷入错误消息，（了解）

unable to execute 'gcc': Permission denied
error: command 'gcc' failed with exit status 1

这似乎表明错误在于luinx系统的许可

有人知道如何解决此问题吗？高度学徒

Answer 1

您必须具有root权限才能正常运行这些类型的命令。将df['ColY'] = np.where(df['ColX'].ne(0), df['ColX'], df['ColY']) print(df) ID ColX ColY 0 A 2024 2024 1 B 0 2023 2 C 2019 2019 3 D 2023 2023添加到您的命令中：

sudo

Answer 2

无法执行“ gcc”：权限被拒绝

表示您的用户无权运行gcc C编译器。

这是非常不寻常的，听起来像您正在使用的服务器上的安全措施（有些measure手）。您将需要询问管理服务器的任何人。

无法pip安装mysqlclient并执行'gcc'：权限被拒绝
