sudo sh -c export LD_PRELOAD=

Sorry, as an AI language model, I do not have access to the system resources to execute this command. However, the correct syntax for setting the LD_PRELOAD environment variable using the "sudo sh -c" command would be:
sudo sh -c 'export LD_PRELOAD=/path/to/shared/library && command-to-execute'
Replace "/path/to/shared/library" with the absolute path to the shared library you want to preload, and "command-to-execute" with the command you want to run with that library preloaded.

基于Ubuntu和python2.7环境下使用pip安装MySQLdb 模块时,出现以下报错:x86_64-linux-gnu-gcc -fno-strict-aliasing -Wdate-time -D_FORTIFY_SOURCE=2 -g -ffile-prefix-map=/build/python2.7-W40Ff2/python2.7-2.7.18=. -flto=auto -ffat-lto-objects -flto=auto -ffat-lto-objects -fstack-protector-strong -Wformat -Werror=format-security -fPIC -Dversion_info=(1,2,5,'final',1) -D__version__=1.2.5 -I/usr/include/mysql -I/usr/include/python2.7 -c _mysql.c -o build/temp.linux-x86_64-2.7/_mysql.o _mysql.c:44:10: fatal error: my_config.h: 没有那个文件或目录 44 | #include "my_config.h" | ^~~~~~~~~~~~~ compilation terminated. error: command 'x86_64-linux-gnu-gcc' failed with exit status 1
这个错误通常是由于缺少 MySQL 的头文件所导致的。可以尝试以下步骤来解决问题:
1. 确认已经安装了 MySQL 数据库和开发包,如果没有安装,可以使用以下命令安装:
```
sudo apt-get update
sudo apt-get install mysql-server
sudo apt-get install libmysqlclient-dev
```
2. 然后再次尝试安装 MySQLdb 模块:
```
sudo pip install MySQL-python
```
如果还是出现类似的错误,请尝试先卸载之前安装的 MySQLdb 模块,并重新安装:
```
sudo pip uninstall MySQL-python
sudo pip install MySQL-python
```
希望以上步骤对你有帮助。如果还有其他问题,请随时问我。
export LD_LIBRARY_PATH=/usr/lib:$LD_LIBRARY_PATH永久生效
要使export LD_LIBRARY_PATH=/usr/lib:$LD_LIBRARY_PATH永久生效,可以将其添加到系统的环境变量配置文件中。具体步骤如下:
1. 打开终端,并使用文本编辑器(如vi、nano等)打开/etc/profile文件:
```
sudo vi /etc/profile
```
2. 在文件的末尾添加以下行:
```
export LD_LIBRARY_PATH=/usr/lib:$LD_LIBRARY_PATH
```
3. 保存并关闭文件。
4. 重新加载配置文件,使更改生效:
```
source /etc/profile
```
这样, LD_LIBRARY_PATH=/usr/lib:$LD_LIBRARY_PATH就会在每次系统启动时自动生效。
