Question

我已经尝试在Mac上安装SimpleCV好几天了。我终于安装了所有东西，但运行了hello world程序

from SimpleCV import Camera
# Initialize the camera
cam = Camera()
# Loop to continuously get images
while True:
    # Get Image from camera
    img = cam.getImage()
    # Make image black and white
    img = img.binarize()
    # Draw the text "Hello World" on image
    img.drawText("Hello World!")
    # Show the image
    img.show()

在他们的主页上找到

返回以下错误：

  File "helloworld.py", line 13, in <module>
    img.show()
  File "/usr/local/lib/python2.7/site-packages/SimpleCV/ImageClass.py", line 5447, in show
    d = Display(self.size())
  File "/usr/local/lib/python2.7/site-packages/SimpleCV/Display.py", line 158, in __init__
    scvLogo = SimpleCV.Image("simplecv").scale(32,32)
  File "/usr/local/lib/python2.7/site-packages/SimpleCV/ImageClass.py", line 787, in __init__
    self._pil = pil.open(self.filename).convert("RGB")
  File "/usr/local/lib/python2.7/site-packages/PIL/Image.py", line 2237, in open
    fp = builtins.open(fp, "rb")
IOError: [Errno 2] No such file or directory: '/usr/local/lib/python2.7/site-packages/SimpleCV/sampleimages/simplecv.png'
Cleaned up camera.

经过大量的试验和错误后，我最终得到了以下brew包：

atk         eigen           glib            isl         mercurial       pcre            scipy           swig
autoconf        fontconfig      gmp         jpeg            mpfr            pixman          sdl         webp
automake        freetype        gobject-introspection   libffi          numpy           pkg-config      sdl_image       xz
brew-cask       gcc         gtk+            libmpc          opencv          portmidi        sdl_mixer
cairo           gdbm            harfbuzz        libpng          openexr         pygame          sdl_ttf
cloog           gdk-pixbuf      icu4c           libtiff         openssl         python          smpeg
cmake           gettext         ilmbase         libtool         pango           readline        sqlite

以及以下pip包：

funcsigs (0.4)
gnureadline (6.3.3)
ipython (2.3.1)
mercurial (3.2.4)
nose (1.3.4)
numpy (1.9.1)
obd (0.2.0)
Pillow (2.7.0)
pip (6.0.6)
pygame (1.9.1release)
pyparsing (2.0.3)
pyserial (2.7)
scipy (0.14.0)
setuptools (11.3.1)
SimpleCV (1.3)
six (1.9.0)
svgwrite (1.1.6)

安装在我的系统上。

其中一个ubuntu / pip软件包丢失了该文件，它破坏了所有内容。您的文件没有问题。如果你可以从github源代码构建，它将是最好的选择，并会给你更多的模块。 This应该会有帮助。
