如果出现空参数异常，Kpm还原将失败。

Question

我在CentOs 6、CentOs 7和Ubuntu 12.04上尝试了以下几种方法，结果都是一样的：

yum update -y
yum install  git wget unzip -y
yum install glib2-devel libpng-devel libjpeg-devel giflib-devel libtiff-devel libX11-devel fontconfig-devel bison gettext libtool cairo-devel gcc-c++ -y

cd /usr/local/src
git clone git://github.com/mono/mono.git
cd mono
./autogen.sh --prefix=/usr/local
sudo make get-monolite-latest
make EXTERNAL_MCS=${PWD}/mcs/class/lib/monolite/basic.exe 
make install

curl -sSL https://raw.githubusercontent.com/aspnet/Home/master/kvminstall.sh | sh && source ~/.kre/kvm/kvm.sh
chmod a+x /root/.kre/kvm/kvm.sh 
source /root/.kre/kvm/kvm.sh
kvm upgrade


CERTMGR=/usr/local/bin/certmgr
sudo $CERTMGR -ssl -m https://go.microsoft.com
sudo $CERTMGR -ssl -m https://nugetgallery.blob.core.windows.net
sudo $CERTMGR -ssl -m https://nuget.org
mozroots --import --sync

cd /usr/local/src
git clone https://github.com/aspnet/home
cd home/samples/HelloMvc/
kpm restore

我知道这个错误：

谢谢！

编辑:另一次通过yum安装的尝试也会产生同样的错误。在新安装时：

    1  yum update -y
    2  yum install wget git curl unzip -y
    3  yum install yum-utils -y
    4  rpm --import "http://keyserver.ubuntu.com/pks/lookup?op=get&search=0x3FA7E0328081BFF6A14DA29AA6A19B38D3D831EF"
    5  yum-config-manager --add-repo http://download.mono-project.com/repo/centos/
    6  yum search mono-complete
    7  yum install mono-complete
    8  yum update
    9  echo CERTMGR=$CERTMGR
   10  CERTMGR=/usr/local/bin/certmgr
   11  CERTMGR=/usr/bin/certmgr
   12  echo CERTMGR=$CERTMGR
   13  $CERTMGR -ssl -m https://go.microsoft.com
   14  yes | $CERTMGR -ssl -m https://nugetgallery.blob.core.windows.net
   15  yes | $CERTMGR -ssl -m https://nuget.org
   16  yes | $CERTMGR -ssl -m https://www.myget.org/F/aspnetvnext/
   17  mozroots --import --sync
   18  curl https://raw.githubusercontent.com/aspnet/Home/master/kvminstall.sh | sh && source ~/.kre/kvm/kvm.sh
   19  chmod a+x /root/.kre/kvm/kvm.sh
   20  source /root/.kre/kvm/kvm.sh
   21  kvm upgrade
   22  cd /usr/local/src
   23  git clone https://github.com/aspnet/home
   24  cd home/samples/HelloMvc/
   25  ls
   26  kpm restore

Answer 1

也见KRuntime错误。

创建错误的是Mono的控制台实现。赛格色显然是null，因此来自可能的TermInfoReaders之一的阅读失败。

我要说的是，这要么是Mono错误，要么是Mono/CentOS不兼容，要么是丢失的数据包。

您可以检查TERMINFO环境变量或设置术语环境变量来显式地选择TermInfoReader。

将项设置为dumb将禁用整个输出，而每一项操作都会正常工作。
