详解python模块pychartdir安装及导入问题

在迁移别人写好的脚本时，发现pychartdir没有导入，脚本执行报错。以下是报错内容：

[modps@LGJF-ZYC5-MMSC-WEB02 ~]$ python /opt/aspire/product/modps/mopps/shell/dayreport_linux.py
/etc/host.conf: line 1: bad command `nospoof on'
Traceback (most recent call last):
 File "/opt/aspire/product/modps/mopps/shell/dayreport_linux.py", line 42, in <module>
 from pychartdir import *
ImportError: No module named pychartdir

之前使用的是pip来安装模块的，先安装下pip：

curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
sudo python get-pip.py

然后开始下载pychartdir模块：

[root@LGJF-ZYC5-MMSC-WEB02 ~]# pip install pychartdir
DEPRECATION: Python 2.7 reached the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 is no longer maintained. pip 21.0 will drop support for Python 2.7 in January 2021. More details about Python 2 support in pip can be found at https://pip.pypa.io/en/latest/development/release-process/#python-2-support pip 21.0 will remove support for this functionality.
/etc/host.conf: line 1: bad command `nospoof on'
ERROR: Could not find a version that satisfies the requirement pychartdir (from versions: none)
ERROR: No matching distribution found for pychartdir

发现报错了，报错的大概意思为：未找到合适的版本。

那么就只好手动安装了

1.从官方地址下载python版本的ChartDirector并解压

https://www.advsofteng.com/download.html

# 使用lrzsz命令将下载的包传递到服务器上
[root@LGJF-ZYC5-MMSC-WEB02 ~]# tar -xf chartdir_python_linux_64.tar.gz

2.在python模块安装目录下（/usr/lib/python2.7/site-packages）创建一个chartdirector的目录

# 查看模块安装目录
[root@LGJF-ZYC5-MMSC-WEB02 ~]# python
Python 2.7.5 (default, May 3 2017, 07:55:04) 
[GCC 4.8.5 20150623 (Red Hat 4.8.5-14)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import sys
>>> print(sys.path)
['', '/usr/lib64/python27.zip', '/usr/lib64/python2.7', '/usr/lib64/python2.7/plat-linux2', '/usr/lib64/python2.7/lib-tk', '/usr/lib64/python2.7/lib-old', '/usr/lib64/python2.7/lib-dynload', '/usr/lib64/python2.7/site-packages', '/usr/lib64/python2.7/site-packages/gtk-2.0', '/usr/lib/python2.7/site-packages']
>>> 
[root@LGJF-ZYC5-MMSC-WEB02 ~]# cd /usr/lib/python2.7/site-packages
[root@LGJF-ZYC5-MMSC-WEB02 site-packages]# mkdir chartdirector
[root@LGJF-ZYC5-MMSC-WEB02 site-packages]# cd chartdirector
[root@LGJF-ZYC5-MMSC-WEB02 chartdirector]# pwd
/usr/lib/python2.7/site-packages/chartdirector

3.进入解压好的Chartdirector/ lib，将其下面的内容拷贝到上边创建的目录下，同时在site-packages下创建一个chartdirector.pth，写入chartdirector到文件中：

[root@LGJF-ZYC5-MMSC-WEB02 chartdirector]# cd
[root@LGJF-ZYC5-MMSC-WEB02 ~]# cd ChartDirector/lib/
[root@LGJF-ZYC5-MMSC-WEB02 lib]# cp -a ./* /usr/lib/python2.7/site-packages/chartdirector/
[root@LGJF-ZYC5-MMSC-WEB02 lib]# cd /usr/lib/python2.7/site-packages/
[root@LGJF-ZYC5-MMSC-WEB02 site-packages]# cat chartdirector.pth
chartdirector

4.打开python IDE，导入该模块试试：

[root@LGJF-ZYC5-MMSC-WEB02 site-packages]# python
Python 2.7.5 (default, May 3 2017, 07:55:04) 
[GCC 4.8.5 20150623 (Red Hat 4.8.5-14)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import pychartdir

5.运行脚本，执行成功！
