python - PIL 库未加载 :/opt/local/lib/libjpeg. 9.dylib

Question

我有一个用 django 设计的完美运行的网站，但我不小心卸载了 Homebrew 软件，因此所有的包 postgres、Pillow 等都丢失了，因此再次安装了所有这些包，但是当我运行 django runserver 时，我得到了低于错误

我尝试了与它相关的 stackoverflow 帖子上可用的所有内容，例如

brew uninstall libjpeg
brew install libjpeg

但它们都不起作用，而我的 brew list

boost       gdal        gmp     liblwgeom   libxml2     mysql       postgis     sfcgal
cgal        geoip       jpeg        libpng      little-cms2 openssl     postgresql  sqlite
freetype    geos        json-c      libspatialite   lzlib       pcre        proj        webp
freexl      giflib      libgeotiff  libtiff     mpfr        pillow      readline

那么为什么它不能加载 /opt/local/lib/libjpeg.9.dylib 库？以及如何修复它？

对于这种特殊类型的问题，以下对我有用

pip install --upgrade pillow
