Question

我在通过柯南安装和使用qt时遇到问题。实际错误如下所示：

import numpy as np
import netCDF4 
import netCDF4 as nc
import pandas as pd
import numpy as np
import csv
#### === User-inputs ====#####
one = nc.Dataset('1979.nc') ##load one of your nc datafiles

print one.variables ## Check variables names, say my variable names are lat, lon, pre

我设法通过在[requires] gtest/1.8.1@bincrafters/stable boost/1.70.0@conan/stable jsonformoderncpp/3.7.0@vthiery/stable qt/5.13.0@bincrafters/stable [generators] cmake [options] qt:with_mysql=False部分添加bzip2/1.0.8@conan/stable来解决这种依赖性，但是我的应用程序缺少必需的字体：

[requires]

此QFontDatabase: Cannot find font directory /home/<user>/.conan/data/qt/5.13.0/bincrafters/stable/package/82f32da7b204a38af07f00f05f94ebbfd7454b77/lib/fonts. Note that Qt no longer ships fonts. Deploy some (from https://dejavu-fonts.github.io/ for example) or switch to fontconfig.目录实际上丢失了。请注意，该项目在其他同事，同一台机器上构建和运行时都没有此类问题。

问题是-造成这些问题的原因以及如何解决这些问题？

Answer 1

应该通过切换到qt/5.13.1@bincrafters/stable解决依赖冲突，因为许多依赖已迁移到柯南中心。关于字体问题，我正在对qt配方中的fontconfig/2.13.1@conan/stable添加可选的依赖项。在此期间，您可以尝试安装系统版本的fontconfig，重建qt配方，然后检查输出是否具有“ Fontconfig ..................... ........是的”
