Ubuntu /usr/bin/ld: cannot find -lsasl2 在安装 monary 时出错。

我正在尝试安装monary，并遇到以下错误：

x86_64-linux-gnu-gcc -pthread -shared -Wl,-O1 -Wl,-Bsymbolic-functions -Wl,-Bsymbolic-functions -Wl,-z,relro -fno-strict-aliasing -DNDEBUG -g -fwrapv -O2 -Wall -Wstrict-prototypes -Wdate-time -D_FORTIFY_SOURCE=2 -g -fstack-protector-strong -Wformat -Werror=format-security -Wl,-Bsymbolic-functions -Wl,-z,relro -Wdate-time -D_FORTIFY_SOURCE=2 -g -fstack-protector-strong -Wformat -Werror=format-security build/temp.linux-x86_64-2.7/monary/cmonary.o -L/usr/local/lib -L/usr/local/lib -lbson-1.0 -lcrypto -lssl -lsasl2 -lmongoc-1.0 -o build/lib.linux-x86_64-2.7/monary/libcmonary.so
/usr/bin/ld: cannot find -lsasl2
collect2: error: ld returned 1 exit status
error: command 'x86_64-linux-gnu-gcc' failed with exit status 1

我查看了usr-bin-ld-cannot-find-lz，但仍然不知道lsasl2是哪个软件包的一部分？（以便我可以使用sudo apt-get安装它）

而且，ld不是/usr/bin/目录的一部分。它是一个linux x86可执行文件。我应该如何解决这个问题？

我使用的是16.04.4 LTS xenial Ubuntu。

完整的错误和执行结果如下：

我想安装monary以便我不必使用pd.DataFrame(list())，这对于30万个属性来说非常慢。
