求各位大神帮助，论坛币实在不多。。。
程序是这样的：
url <- "http://drygin.ccbr.utoronto.ca/~costanzo2009/sgadata_costanzo2009_rawdata_101120.txt.gz"
download.file(url, file.path("Data", "sgadata_costanzo2009_rawdata_101120.txt.gz"), method="curl")

错误是这样的：
Error in download.file(url, file.path("Data", "sgadata_costanzo2009_rawdata_101120.txt.gz"),  :
  'curl' call had nonzero exit status
In addition: Warning message:
running command 'curl  "http://drygin.ccbr.utoronto.ca/~costanzo2009/sgadata_costanzo2009_rawdata_101120.txt.gz"  -o "Data/sgadata_costanzo2009_rawdata_101120.txt.gz"' had status 127
这究竟是怎么回事，菜鸟一个，还求大神帮忙看下
