blocks|key|941282|text|很可能您的conda环境有一个较旧的libtinfo.so.6库，并且当您将conda路径导出到LD_LIBRARY_PATH时，这个会话中需要libtinfo.so.6的每个程序都将从您的conda环境中加载库。现在，当bash想要加载libtinfo.so.6时，它需要一个包含特定符号的更新版本，但是conda的库没有提供这个符号，因此ld抱怨没有可用的版本信息。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|941283|如果您正在运行一个可执行文件，或者您正在编译一个需要这个库的程序，您可以简单地在运行的程序之前追加环境变量。例如，LD_LIBRARY_PATH=$HOME/.miniconda3/envs/ll4ma/lib:$LD_LIBRARY_PATH+/bin/bash将使用前面指定的LD_LIBRARY_PATH运行bash。这将将更改后的环境变量的范围限制在这一行，这样您的全局环境就不会受到影响。解决此问题的另一种方法是简单地删除conda环境中的libtinfo.so.6+(确保在删除它之前备份)，并测试您的程序是否还能运行。在许多情况下，库是设计成与ABI兼容的，所以使用更新版本的库不会破坏任何东西。|offset|length|style|CODE|941284|entityMap^0|0|1L|23|0^^$0|@$1|2|3|4|5|6|7|J|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|K|8|@$D|L|E|M|F|G]]|9|@]|A|$]]|$1|H|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|I|$]]

It's likely that your conda environment has an older libtinfo.so.6 library and when you export conda path to LD_LIBRARY_PATH every program in this session that requires libtinfo.so.6 will load library from your conda environment. Now when bash wants to load libtinfo.so.6, it expects a newer version with specific symbol in it, but the library from conda doesn't provide that symbol, so ld is complaining that no version information available.
If you are running an executable or you are compiling a program that requires this library, you can simply append the environment variable before the program you are running. For example, <code>LD_LIBRARY_PATH=$HOME/.miniconda3/envs/ll4ma/lib:$LD_LIBRARY_PATH /bin/bash</code> will run bash using the LD_LIBRARY_PATH specified before it. This will limit the scope of changed environment variable to this line so your global environment is not affected. Another way to solve the problem is to simply delete libtinfo.so.6 in your conda environment (make sure to make a backup before deleting it) and test if your program can still run. In many cases the libraries are designed to be ABI compatible so use a newer version of library won't break anything.

blocks|key|1795583|text|事实证明，libtinfo的版本(作为ncurses的一部分安装)没有提供这个相关的答案中建议的版本信息。我能够通过强制从ncurses通道安装conda-forge来解决这个问题，而不是默认情况。在我的conda+env的YAML配置中，我只做了以下操作：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1795584|dependencies:

It turns out that the version of <code>libtinfo</code> (installed as part of <code>ncurses</code>) doesn't provide its version info as suggested in <a href="https://askubuntu.com/a/1405336/314637">this related answer</a>. I was able to resolve this by forcing <code>ncurses</code> to be installed from the <code>conda-forge</code> channel instead of the default. In my YAML config for my conda env I simply did this:
<pre class="lang-yaml prettyprint-override"><code>dependencies:
 - conda-forge::ncurses
</code></pre>
If installing from command line you can do
<pre class="lang-bash prettyprint-override"><code>conda install -c conda-forge ncurses
</code></pre>
If you don't specify the channel then you would need to set the channel priority as described <a href="https://docs.conda.io/projects/conda/en/latest/user-guide/tasks/manage-channels.html" rel="noreferrer">here</a> so that it will give priority to <code>conda-forge</code>.
Using the version of <code>ncurses</code> from <code>conda-forge</code> instead of the default got rid of the message that was spamming my terminal, because the <code>conda-forge</code> one ships with version information as described <a href="https://stackoverflow.com/a/38851073/3711266">here</a>.

I have a conda environment setup and had to set my <code>LD_LIBRARY_PATH</code> like this:
<pre><code>export LD_LIBRARY_PATH=$HOME/.miniconda3/envs/ll4ma/lib:$LD_LIBRARY_PATH
</code></pre>
However as soon as I did this, I started getting my terminal flooded with this message:
<pre><code>/bin/bash: /home/ll4ma/.miniconda3/envs/ll4ma/lib/libtinfo.so.6: no version information available (required by /bin/bash)
</code></pre>
Any idea how to fix this? I'm building some code for ROS with <code>catkin</code> and this message gets printed maybe 20 times in the process, which makes the terminal output very hard to look at.
